GIC SM500 MG73BH Voltage Monitoring, For Control Panel, 3 Pole

Inclusive of all taxes

The GIC SM500 MG73BH is an advanced 3-pole voltage monitoring relay specifically designed for industrial control panel applications. This DIN rail-mounted voltage monitoring device is part of GIC's SM500 series and ensures reliable phase and voltage supervision in three-phase power supplies. Supporting input voltages of 230Vac (single phase) and 3x400Vac / 3x415Vac (three-phase, 4-wire), the MG73BH model provides precise voltage protection by detecting phase failure, undervoltage, and overvoltage conditions. Equipped with 2 C/O (changeover) outputs, it enables seamless integration with control circuits to prevent equipment damage caused by voltage anomalies. The relay's selectable under-voltage and over-voltage threshold settings offer tailored protection to match various industrial power requirements. Its robust construction and easy DIN rail mounting make the GIC SM500 MG73BH an essential component for maintaining power quality and safeguarding electrical installations in industrial environments.
