Why Choose the ABB S302P-C40 Miniature Circuit Breaker?
The ABB S302P-C40 (Product ID: 2CDS382001R0404) is a high-performance 2-pole miniature circuit breaker (MCB) designed to protect industrial electrical installations against overloads and short circuits. As part of the advanced ABB System pro M compact S300P series, it combines a compact modular design with a high short-circuit breaking capacity for dependable circuit protection.
Featuring a Type C tripping characteristic, the S302P-C40 is suitable for circuits supplying equipment with moderate starting currents, including motors, lighting systems, control equipment and general industrial loads. Its thermal and electromagnetic tripping mechanisms provide reliable protection under both sustained overload and sudden short-circuit conditions.
With a rated current of 40 A, a 2-pole configuration and a rated operational voltage of up to 415 V AC, this ABB circuit breaker is ideal for industrial control panels, machinery and power distribution systems. Its DIN rail format enables straightforward installation alongside other System pro M compact modular devices.

Reliable Protection for Industrial Electrical Systems
Miniature circuit breakers such as the ABB S302P-C40 automatically disconnect a circuit when an overload or short circuit is detected. This helps prevent excessive conductor temperatures, equipment damage and electrical hazards while allowing the breaker to be reset after the fault has been corrected.
The Type C tripping characteristic provides a balanced response for general industrial and commercial loads. It tolerates the temporary inrush currents produced by many motors, transformers and lighting systems while maintaining effective protection against dangerous fault currents.
Typical Applications
- Industrial control panels and switchboards.
- Commercial and industrial distribution systems.
- Electric motors and machinery circuits.
- Lighting and heating circuits.
- Automation and production equipment.
- OEM machine building and panel manufacturing.
