WHAT IS SWITCHGEAR?

SWITCH. ISOLATE.
PROTECT.

Switchgear covers the devices used to switch, isolate and protect electrical circuits. Different components perform different jobs: circuit breakers provide protection against specified electrical faults, isolators provide a means of disconnection, and contactors allow equipment to be switched through a control circuit.

CHOOSING COMPONENTS THAT WORK TOGETHER

IT'S MORE THAN
THE CURRENT RATING.

Selection involves more than matching the current rating on a label. Supply voltage, fault level, load type, coil voltage, switching duty and enclosure conditions all affect suitability.

For motor circuits, the protective device, contactor and overload arrangement must be considered together. TM Engineering can assist with component selection and the related control panel work.
