DIN rail using the embedded spring-loaded locking clips. Ensure there is a minimum of clearance around its ventilation paths. Step 2: Line Source Connection
Disconnect control wire; if output stays high, replace thyristor module.
: Two normally open (NO) and two normally closed (NC) contacts. Connection Capacity : 250VAC 6A or 30VDC 3A. Dimensions : Approximately 79mm x 23mm x 79mm.
Central air conditioning and large compressors. Machinery: Elevators, escalators, cranes, and oil pumps.
It is likely you are referring to the (or the generic GMR-32 series) 3-Phase Motor Protection Relay/Phase Controller. These devices are commonly used in industrial settings to protect motors from phase loss, phase unbalance, and incorrect phase sequence.
