AC switch-plug combination for circular saws, planing machines, shredders or other machines and motors, which after power failure and power recovery are not allowed to turn back on.
Required for machines for commercial operation, which do not have an engine brake, but are required to have one.
- 3-pole switching. Nur for mains connection with neutral conductor suitable.
- Switching capacity up to 4 kW
- Braking electronics, braking current up to 16 A adjustable
- Undervoltage release
- Phase inverter
- Connection possibility for thermal contact
- Splash water proof cover
This switch in inverted construction (ST9) with Coil voltage 400V: SSK850-ST9.
The neutral conductor is not routed to the motor.
Not suitable for mains connection or extension cables without neutral conductor and
motors in delta connection, which for example need a voltage of 230V in the terminal box for a electromechanical brake.
If needed a brake can be tapped between a phase and a star point 230V for motors in star connection.
Installation / connection (refer to wiring diagram) / brake
The switch is screwed on the housing base. Grid dimension of the screws: 68 x 68 mm.
The cable outlet is on the side of the housing base, by factory setting on the opposite side of the plug.
by rotating the base, the cable can be routed to all 4 sides.
The blue wire is not a neutral conductor, it's the connection for the thermal contact.
If the motor does not have a thermal contact, the blue wire has to be connected with the grey wire on the terminal board.
The brake is by factory setting set to the lowest current.
The braking current can be adjusted with a potentiometer.
