Why Choose the ABB 2CDS383103R0258 S303P-Z1.6NA Miniature Circuit Breaker?
The ABB 2CDS383103R0258, also known as the S303P-Z1.6NA, is a premium miniature circuit breaker (MCB) designed to provide highly sensitive protection against overloads and short circuits in industrial and commercial electrical installations. As part of ABB's trusted S300P System pro M compact range, it combines exceptional fault-clearing performance, international approvals and a compact DIN rail design for demanding applications.
Featuring a 3P+N configuration, the S303P-Z1.6NA protects all three phase conductors while incorporating a switched neutral pole. Its Type Z tripping characteristic is specifically designed for highly sensitive electronic equipment, PLCs, instrumentation and semiconductor circuits that require rapid disconnection under even relatively small fault currents.
With a rated current of 1.6 A, a rated operating voltage of 415 V AC, a 25 kA rated short-circuit breaking capacity (Icn) and a 100 kA ultimate breaking capacity (Icu), the ABB S303P-Z1.6NA delivers dependable protection for industrial automation systems, machine control panels and OEM equipment.
