Why Choose the ABB 2CDS381103R0378 S301P-Z6NA Miniature Circuit Breaker?
The ABB 2CDS381103R0378, also identified as the S301P-Z6NA, is a high-performance miniature circuit breaker (MCB) designed to protect sensitive industrial electrical circuits against overloads and short circuits. It forms part of the reliable ABB System pro M Compact S300P series.
Manufactured for demanding industrial installations, this circuit breaker combines a high short-circuit interruption capability with a sensitive Type Z tripping characteristic. Its integrated trip indication supports rapid fault identification, while fail-safe terminals and a dual DIN rail release help simplify installation and maintenance.
With a rated current of 6 A, a 1P+N configuration and a 240 V AC rated voltage, the ABB 2CDS381103R0378 is particularly suitable for electronic equipment, control circuits, instrumentation and automation systems that require rapid disconnection at relatively low fault-current levels.
