Description
Automatic Star-Triangle Switch / Star-Triangle Time Relay 24VAC/DC – 240V AC with 1 switching contact.
Automatic Star Triangle Switch – Star-Triangle Time Relays are designed for use for the initial start-up of three-phase motors. When the coil is energized, it will switch to star wiring to allow the motor to start. The star stays connected for a set period of time and then goes into standby mode. After the waiting period, it allows switching to delta connection. It therefore provides efficiency by reducing the current drawn by motors using high power during starting.
The time relay mounts on a standard 35mm DIN rail
