Benefits
Manual motor starters are electromechanical protection devices for the main circuit.
They are used mainly to switch motors manually ON/OFF and protect them fuse less against short circuit and loss-phase.
None-fuss protection with a manual motor starter saves costs‚ space and ensures a quick reaction under short-circuit condition‚ by switching off the motor within milliseconds.
Manual motor starter combinations are setup together with contactors and overload relays.
- Available with enclosed coils for protection against particle contamination
- Short-circuit protection
- Disconnect function
- Overload protection
- Loss-phase protection
- Suitable for three and single-phase application
- Trip-free mechanism
- Clear switch position indication ON/OFF/TRIP
- Lockable handle
