Why Choose the ABB 2CDS381001R0258 Miniature Circuit Breaker?
The ABB 2CDS381001R0258, also known as the S301P-Z1.6, is a premium single-pole miniature circuit breaker (MCB) from the ABB System pro M compact S300P series. It is designed to provide dependable protection against overloads and short circuits in industrial electrical installations where highly sensitive magnetic tripping is required.
Featuring a Type Z tripping characteristic, the S301P-Z1.6 is specifically engineered for protecting highly sensitive electronic equipment, PLCs, semiconductor devices, instrumentation, control circuits and measuring equipment. Its fast magnetic response helps prevent damage to delicate components from even relatively low fault currents.
With a 1.6 A rated current, a compact single-pole configuration and a 25 kA short-circuit breaking capacity, the ABB 2CDS381001R0258 delivers exceptional circuit protection whilst maintaining compatibility with ABB's complete System pro M compact accessory range.

Ultra-Sensitive Type Z Circuit Protection
The ABB S301P-Z1.6 is designed for applications where rapid disconnection is essential to protect sensitive electronic devices. Its highly sensitive Type Z characteristic trips magnetically at approximately two to three times the rated current, providing significantly faster protection than standard Type B, C or D circuit breakers.
This makes the breaker particularly suitable for PLC systems, industrial automation, semiconductor equipment, laboratory instrumentation, measuring equipment and sensitive electronic control circuits where even relatively small fault currents could cause expensive damage.
Typical Applications
- PLC and industrial control systems.
- Electronic control panels.
- Instrumentation circuits.
- Laboratory equipment.
- Semiconductor manufacturing equipment.
- Measuring devices.
- Sensitive automation equipment.
- Industrial electronic protection.
