Why Choose the ABB S801C-B63 High Performance MCB?
The ABB S801C-B63 is a high-performance single-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding electrical distribution systems. As part of the ABB S800C high-performance circuit breaker series, it combines compact DIN-rail installation with high breaking capacity for commercial and industrial applications.
This circuit breaker features a Type B tripping characteristic and a rated current of 63 A. Its thermal tripping mechanism provides overload protection, while its electromechanical tripping mechanism responds rapidly to short-circuit conditions. The current-limiting design helps reduce the energy passed through during fault conditions and protects downstream electrical equipment.
With a rated ultimate short-circuit breaking capacity of 25 kA at 240 V AC according to IEC 60947-2, the S801C-B63 is suitable for installations requiring substantially higher fault-current performance than conventional miniature circuit breakers. Its robust construction, cage terminals and DIN-rail mounting make it well suited to distribution boards, control panels and industrial electrical systems.
