Circuit Breaker for 4 A Circuits

This thermal overload protector is a push-button reset circuit breaker rated for AC 125/250 V and 4 A. It comes as a pack of two units for use in automotive, industrial and marine applications where a compact, resettable circuit interruption device is required.

Practical Limits of the 4 A Rating

The device interrupts the circuit automatically when the load exceeds 4 A and can be reset by pressing the button after a cooling period. It operates at AC 125/250 V and uses a 10 mm thread diameter for panel mounting, making it suitable for panels and enclosures designed for that thread size.

4 A Trip Current Decides Suitability

The single specification that determines whether this breaker fits the application is the 4 A trip current; circuits drawing more than 4 A will cause nuisance tripping, while circuits requiring a lower or higher trip point need a different device.

Questions about this item

Should I choose the 125 V or 250 V version for my application?

This single breaker is rated for both AC 125 V and AC 250 V, so no separate version choice is needed.

What does the 4 A rating mean once the breaker is installed?

If the current through the breaker exceeds 4 A, the thermal mechanism trips and the push-button pops out to cut the circuit.

What interface does the breaker use and what does it limit in practice?

It mounts via a 10 mm threaded bushing and provides thermal overload protection up to 4 A at AC 125/250 V.
