Over Load Relay

Description

Over Load Relay

Thermal overload relay provides protective features for 1 or 3 phase motors. The relay monitors the operating current of the motor and switched the contactor off, in the event of an overload situation. It also protects the motor from damage during a phase loss.

Thermal overload relay performs the following functions:

• Allows harmless temporary overloads (such as motor starting) without disrupting the circuit.
• Trips and open a circuit if the current is high enough to cause motor damage over a while.
• Can be reset once the overload is removed.
