Rotary disconnector under load BCGL 100/63A is the protection device in the power circuit: it trips on overload or fault so the damage stops before the alternator or the installation.
Ageing is counted in trip operations and in environment: dust, moisture and heat degrade the mechanism. On site panels, check terminal torque every year — most nuisance trips start there.

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.
