Why Choose the ABB 2CDS381001R0158 Miniature Circuit Breaker?
The ABB 2CDS381001R0158, also known as the ABB S301P-Z0.5, is a high-performance single-pole miniature circuit breaker (MCB) designed to protect sensitive industrial electrical circuits against overloads and short circuits. As part of the advanced ABB System pro M compact S300P series, it combines precise fault detection with a high breaking capacity for dependable protection in demanding installations.
This miniature circuit breaker uses thermal and electromagnetic tripping mechanisms to disconnect a circuit when unsafe current conditions occur. Its highly sensitive Type Z characteristic is particularly suitable for electronic equipment, control systems and semiconductor-based devices that require rapid protection against relatively low overcurrents.
With a rated current of 0.5 A, a Type Z tripping characteristic and a rated short-circuit breaking capacity of up to 25 kA, the ABB 2CDS381001R0158 is ideal for protecting sensitive loads in industrial automation and control applications. Its compact single-module design enables straightforward installation on a standard DIN rail.

Reliable Protection for Sensitive Electrical Circuits
Miniature circuit breakers such as the ABB S301P-Z0.5 automatically isolate electrical circuits when overload or short-circuit conditions are detected. The thermal mechanism responds to sustained overloads, while the electromagnetic mechanism provides rapid disconnection during sudden fault-current events.
The Type Z characteristic offers more sensitive magnetic operation than standard Type B or Type C breakers. This makes the ABB 2CDS381001R0158 especially suitable for electronic components, programmable controllers, instrumentation and other low-current equipment that could be damaged by relatively small overcurrents.
Typical Applications
- Programmable logic controllers and automation equipment.
- Electronic control and instrumentation circuits.
- Semiconductor and solid-state devices.
- Industrial control panels.
- Measurement and monitoring equipment.
- Low-current auxiliary and signalling circuits.
