Description

The asynchronous motor control wiring kit is dedicated to the realization of real wiring of control and power circuits of asynchronous motors.

It can be used to cover control topics with or without self-holding, integration of the circuit breaker state into the control loop, 1 or 2-way contactors, timed star/triangle switching, reversal of the direction of travel, soft start, frequency variation with or without brake resistors.

The supplied asynchronous motor is equipped with windings for star/delta switching

The coupling of the motor must be adapted according to the proposed wiring diagrams.

This kit is supplied in the form of a pre-equipped box with disconnector, plate, ducts, control knobs and power components mentioned above... The door of the enclosure is transparent in order to visualize the status of the components without affecting the safety of intervention.

The rugged design of this equipment makes it perfectly suited for use in a school setting.

Its anodized aluminum structure on wheels gives it great robustness as well as great flexibility of integration into your premises. The manufacture of this equipment complies with the European Machinery Directive
