MCR Series Motor Control Relays
COMPREHENSIVE PROTECTION • FAST FAULT DIAGNOSIS • DIN RAIL DESIGN
MCR series motor control relays detect electrical faults that shorten motor lifespan in industrial facilities at microsecond level, keeping the system in a safe zone. Continuously monitors critical parameters such as phase loss, phase sequence error, over/under voltage and asymmetry to minimize motor downtime.
Comprehensive Electrical Protection
Continuously monitors phase loss, phase sequence error, over/under voltage and asymmetry parameters to minimize motor downtime.
Compact DIN Rail Housing
Ensures maximum space efficiency in panels with standard DIN rail mounting and 30mm slim housing.
Fast Fault Diagnosis
Front panel LED combinations allow technical personnel to instantly identify whether the fault originates from phase sequence or voltage drop.
Reduced Maintenance Costs
Prevents motor winding overheating, reducing rewinding costs and operational downtime by up to 80%.
