Product Description
Crouzet 84872152 Monitoring Relay is a precision electrical control device designed for voltage monitoring in single-phase AC and DC networks with a power consumption of just 1W. Its SPDT contact configuration and DIN rail mount make it ideal for industrial automation, electrical panels, and signal conditioning applications.
This relay belongs to the MUSF series voltage control relays that provide robust protection by monitoring their own supply voltage. It allows the operator to select operating modes including under-voltage and over-voltage control, with options for fault latching to maintain safety during abnormal supply conditions.
The device incorporates adjustable time delays upon threshold crossing to provide immunity from transient disturbances and prevent spurious relay activation. It measures voltage in true RMS, supporting 50 Hz, 60 Hz alternating current, or DC voltage operation.
Constructed with secure screw terminals, the relay is compact with dimensions 69mm (L) x 92.6mm (H) x 17.5mm (W), facilitating easy installation in DIN rail enclosures. Its protection ratings of IP30 and IP20 ensure adequate resistance against dust and foreign objects in typical industrial environments.
Compliance with international standards such as WEEE, RoHS, NF EN 60255-6, IEC 60255-6, UL 508, and CSA C22.2 No. 14 certifies its reliability and safety for professional electrical systems.
Monitors single-phase AC and DC voltages up to 260 V. Selectable under/overvoltage control with memory and fault latching. Adjustable time delay prevents false relay triggering. True RMS measurement at 50 Hz, 60 Hz, or DC voltage.
LED status display for operational clarity. Compact DIN rail mount design. Screw terminal wiring for secure connections. Standards-compliant for industrial use.
This product is widely used in industrial automation, electrical distribution control, monitoring devices, and facilities management systems to enhance voltage safety and operational reliability.
