Why Choose the ABB S301P-Z8 Miniature Circuit Breaker?
The ABB S301P-Z8 (2CDS381001R0408) is a high-performance single-pole miniature circuit breaker (MCB) designed to protect industrial electrical circuits against overloads and short circuits. As part of the dependable ABB S300P series, it combines precise protection, high breaking capacity and compact dimensions for demanding control and distribution applications.
Featuring a Z tripping characteristic, the S301P-Z8 provides rapid magnetic tripping at comparatively low fault-current levels. This makes it particularly suitable for protecting sensitive electronic equipment, semiconductor devices, instrumentation and control circuits where fast disconnection can help prevent equipment damage.
With an 8 A rated current, a single-pole configuration and compatibility with standard DIN rail mounting, this miniature circuit breaker is ideal for industrial control panels, automation systems and OEM machinery. Its compact 17.5 mm width helps conserve valuable enclosure space while allowing straightforward installation.

Fast Protection for Sensitive Electrical Circuits
Miniature circuit breakers automatically disconnect electrical circuits when an overload or short circuit occurs. This helps protect cables, control equipment and connected devices from excessive current while allowing the circuit breaker to be reset after the underlying fault has been corrected.
The Z tripping characteristic is intended for circuits that require especially sensitive short-circuit protection. It is commonly selected for electronic components, instrumentation and control equipment with low permissible fault currents and minimal start-up surges.
Typical Applications
- Industrial control panels.
- PLC and automation systems.
- Electronic and semiconductor equipment.
- Measurement and instrumentation circuits.
- OEM machinery and production equipment.
- Commercial and industrial distribution systems.
