Circuit Breaker BCM1 1500AMP 3P is a circuit breaker: it opens on overload or short circuit, protecting the generator, the cabling and the downstream load.
A breaker should not trip in normal service. If it opens at the usual load, the cause is nearly always a mis-set trip, loose terminals generating heat, or a breaker sized below the real set current.

How to verify before ordering
- Match rated current, trip curve (B/C/D) and breaking capacity to the circuit it protects.
- Check whether the panel uses a moulded case, DIN rail or open-frame breaker, and how many poles.
- Confirm the kA rating: fitting one below the original leaves the panel unprotected against short circuit.
Frequently asked questions
Why does the breaker trip when the set starts?
The motor inrush or the transformer magnetising current crosses the instantaneous threshold. It is solved with the right curve (type D or a short-delay setting), not by raising the rating without recalculating the cable.
Can I replace it with a higher amperage one?
Not without recalculating cable and alternator. A larger breaker leaves the cable unprotected and pushes the damage into the winding.
