The S-ET 10 (for wall mounting) switch off the supply voltage to the motor when the thermal contact in the motor windings is tripped. The motor protector is connected to a 230V supply and also to the thermal contact in the motor. The motor protector is reset by pressing the black button as soon as the motor windings have cooled sufficiently. The motor protector can also be used in conjunction with a transformer. The S-ET has an alarm contact as an accessorie. The Alarm contact has a built-in potential-free contact for an external signal to indicate when the contact relay has been tripped.
