S281UC-Z3
Interruttore Magnetotermico 1 polo in corrente continua (DC)
General Information
Extended Product Type: S281UC-Z3
Product ID: GHS2810164R0318
Catalog Description:
Miniature Circuit Breakers MCBs - S280UC - Number of Poles 1 - Tripping characteristic Z
Long Description:
System pro M S280UC is a universal
current miniature circuit breaker that provides current limitation. With
its high DC voltage rating it is a excellent solution for DC
applications in photovoltaic’s, telecommunication, traction and
industrial applications. They have two different tripping mechanisms,
the delayed thermal tripping mechanism for overload protection and the
electromechanic tripping mechanism for short circuit protection. They
are available in different characteristics (B,K,Z), configurations
(1P,2P,3P,4P), breaking capacities (up to 6 kA at 230/400 V AC) and
rated currents (up to 63A). All MCBs of the product range S280UC comply
with IEC/EN 60947-2, UL1077 and CSA 22.2 No. 235, allowing the use for
commercial and industrial applications in direct current circuits for
voltages up to 220 V DC 1 pole and 440 V DC 2, 3 and 4 poles.
