FS340040A - 40Amp Circuit Breaker Description
FS340040A - 40Amp Circuit Breaker
The FS340040A is a 40 Amp, 3-pole molded case circuit breaker used in your electrical equipment that requires an FS frame breaker. It is typically found in commercial and industrial systems where replacing an existing breaker means matching the original specifications rather than changing the equipment layout. Getting the details right — including the frame type, amp rating, pole configuration, and interrupting capacity — helps ensure the replacement fits the application it was intended for.
Key Features and Benefits
- 40 Amp molded case circuit breaker
- Three-pole configuration for three-phase electrical applications

- Non-interchangeable trip unit
- Includes load terminals
- Rated for 40°C ambient temperature operation
- Helps preserve the original breaker arrangement
- Suitable for commercial and industrial electrical distribution systems
- Molded case construction built to last
