Motor Circuit Breakers
Metaltex motor circuit breakers (motor starters) are three-pole devices designed for the control, operation, and protection of three-phase induction motors. They integrate overload, short-circuit, phase-loss, and undervoltage protection functions into a single unit, operating with an electromechanical trip class of 10 A. Versions are available with either push-button or rotary actuators, equipped with adjustment dials that allow the thermal trip limit to be set for optimal matching with the motor's rated current. They support a rated insulation voltage (Ui) of 690 VAC and offer a high short-circuit breaking capacity (Icu) of up to 100 kA at 380 V/440 V, in compliance with the international standard IEC 60947. A variety of accessories is available.
