These class I+II devices, type T1+T2, are designed to suppress direct discharges and indirect overvoltages. Surge arrester class I+II in accordance with IEC 61643‑31 Surge arrester type T1+T2 in accordance with EN 61643‑31 Versions with an operating voltage of DC 1000V Replaceable inserts Optical indication of insert damage Watch the video about surge arresters and see the full range of low voltage protections A mandatory element of the electrical installation in your home. Protection against electrical surges. The type 1+2 (formerly B+C) surge protector is installed to protect electrical installations against the effects of indirect lightning discharges and switching surges. It is used as a supplement to protection behind type 1 arresters in sub-distribution boards. BRANCHED SWITCHBOARDS | STOREY SWITCHBOARDS | DISTRIBUTION BOARDS Why choose an Eaton surge arrester? Full safety Protects against the effects of direct and indirect discharge. Replaceable varistor inserts (and their damage indication) This type of limiter is an ideal protection against overvoltages resulting from indirect lightning discharges or switching processes in the electrical network. Quick verification of the device's condition. The red field on the optical cartridge damage indicator means that the cartridge needs to be replaced. Green - the device is working properly. Easy to install, convenient to use Information about the device status at your fingertips Optical insert burnout indicator Elevator and rail terminals Information about key parameters Simple installation on a DIN rail Technical specifications: Type: SPPVT12-10-2+PE Limiter type: PV T1 and PV T2 Size: 3 modules Actuation indication on the device: Optical Rated DC voltage [V]: 1000 Maximum discharge current Imax [kA]: 40 Rated discharge current (8/20 us): 15kA Surge current Iimp (10/350) μs, : 5kA Protection level (L+) - (L-) Up ≤ 3.5 kV Protection level (L+/L-) – PE Up ≤ 3.5 kV Main factors of overvoltages Severe storms or electrical failures can lead to overvoltages. These, in turn, damage the electrical installation. As a result, electrical equipment connected to the network may be destroyed. Therefore, industrial, service and residential facilities should be equipped with a lightning protection system and surge protectors. Protection against lightning discharges and switching overvoltages is very important for the safety of the facility. It can reduce fire and shock hazards in the facility. Surge limiters in electrical installations Surge limiters are used to protect electrical devices against the effects of overvoltages, lightning and lightning strikes. An increase in voltage in the network caused, for example, by a lightning strike, triggers the limiter and reduces the voltage in the network to a level that is safe for electrical receivers. A surge arrester is a mandatory protection for every electrical installation in Poland. EATON surge arresters provide effective surge protection. Their advantage is the use of varistors, which are characterized by speed of operation and exceptional ability to absorb energy. Additionally, they have an optical damage indicator that will allow you to take action in time when the device is damaged. SPCT2 surge arresters should be installed in: 1 2 3 4 5 buildings with an external lightning protection installation buildings with an external overhead line and lightning protection installation a protected facility in which an internal steel structure is used as a lightning protection installation buildings powered by a cable line when the distance between the building and the transformer station is small (possibility of occurrence of high short-circuit currents) in facilities without a lightning protection system in close proximity to tall facilities when the grounding electrodes of the facilities are connected Get to know the Eaton product range and choose the right arrester for yourself Test class I/II for photovoltaic installations [T1/2 PV] Test class II for a photovoltaic installation [T2 PV] Test class I/II [T1/2] Test class II [T2] Test class III [T3] Self-assembly on a DIN rail Connect to the currently used installation The sets are recommended to be installed (considered from the power supply side) in front of measuring and residual current devices. This prevents faulty operation of residual current circuit breakers during surge current flow after activation of surge arresters. The world's demand for electricity continues to grow. Eaton is an intelligent energy management company committed to protecting the environment and improving the quality of life for people around the world. We provide electrical solutions that use less energy, improve power reliability and make workplaces and homes safer and more comfortable. We sell our products in over 175 countries. Frequently asked questions What is a surge arrester? A surge arrester is an electrical protection designed to protect electrical installations and devices against the effects of lightning and switching overvoltages. Is a surge arrester mandatory? Since 2002, in accordance with the regulation on the technical conditions to which buildings and their location should be subject, surge arresters have been required in newly constructed facilities as an element of protection against lightning discharges. Which surge arrester should you choose for your home? To protect a single-family house, a class 1+2 (former B+C) surge arrester is most often used as a 2-in-1 device protecting against the direct and indirect effects of lightning. When do we use a surge arrester? A surge arrester should protect every electrical installation put into operation after April 2002. Lightning is a phenomenon that can be experienced by anyone, and even if we are dealing with older buildings, they are just as exposed to the impact of lightning as newly constructed ones. How to connect a surge arrester? Surge arresters have marked terminals - we connect the power cables from the top of the device and the protective conductor from the bottom. In addition, the cables should be tightened with a torque wrench to prevent the cables from falling out of the terminals when the surge current is being discharged. How to secure a surge arrester? The surge arrester does not protect against short-circuit current, therefore it must be protected against the effects of short circuits and overloads. Eaton recommends the use of a fuse insert. There is a precise marking of the maximum value (insert current) in the instructions for each limiter and on the front of the device. How to install a surge arrester? The surge arrester is mounted on the TH bus in the electrical switchboard, maintaining the appropriate cross-sections of the cables and their appropriate length. The device has marked terminals that indicate from which side to power the device (from the top) and from which side to connect the protective conductor (from the bottom) and then to ground the installation. How to check a surge arrester? EATON surge arresters have an optical cartridge burnout indicator. Green means the cartridge is functional, and red means that the cartridge is damaged and should be replaced. In the case of 3+1 arresters with a summing spark gap, the insert with the spark gap is blue, and when damaged, it is red. Additionally, you should always visually inspect the camera. What kind of surge arrester in the block? In blocks commissioned after 2002, surge arresters will be installed in the main switchboards. However, they are located at a large distance from the protected premises, so it is recommended to additionally protect the devices in the premises - with a type 2 (former C) SPCT2 limiter in the residential board and sensitive receivers such as a refrigerator, smart TV or router with type 3 (former D) limiters of the SPDT3 series. In old buildings, it is recommended to install a class I+II (formerly B+C) arrester instead of using a class II limiter in the residential panel. Which surge arrester is suitable for photovoltaics? In photovoltaic installations with panels on the roof without a lightning protection system, a class II (former C) arrester, SPPVT2 from EATON, is sufficient. When the panels are free-standing or the building has a lightning protection system, a type 1+2 arrester, SPPVT12 from EATON, should be used.
