GMR 32B Phase Sequence Failure Protector MUNEFE Phase Relay 380VAC

Description

Product Overview

The GMR 32B Phase Sequence Failure Protector is engineered to deliver comprehensive monitoring and protection for three‑phase electrical systems used in a wide range of industrial applications. Constructed with a durable metal housing and high‑quality insulating copper wiring, the device provides a reliable interface between power sources and critical loads such as motors, compressors, and distribution panels. Its compact dimensions of 3.54 x 3.54 x 1.18 inches and lightweight design (4.4 ounces) allow for easy integration into standard DIN rail or HT35 rail mounting configurations. The protector operates at a rated voltage of 380VAC and is compatible with AC 50/60 Hz power supplies, making it suitable for environments where voltage fluctuations and phase anomalies are common. Five distinct indicator lights give instant visual feedback on normal operation, phase loss, reverse phase, over‑voltage, and undervoltage conditions, enabling rapid response to protect equipment and maintain system stability.

Usage

Designed for versatility, the GMR 32B can be deployed across a variety of industrial settings where three‑phase power is essential. Typical installations include air compressors in manufacturing plants, electric motors driving conveyor systems, central air‑conditioning units in commercial buildings, and pump stations in water treatment facilities. The protector’s ability to detect and signal phase sequence errors helps prevent costly motor damage caused by incorrect wiring or sudden phase loss. Its robust construction ensures reliable performance in harsh environments, including dusty workshops, high‑temperature factories, and outdoor distribution boxes exposed to weather elements. The device’s straightforward rail‑type base with M4 screw holes simplifies mounting on existing control panels, reducing downtime during installation or maintenance. Users benefit from the clear visual indicators, which allow technicians to quickly diagnose issues without the need for complex diagnostic equipment.

FAQ

What types of equipment can the GMR 32B protect?

The protector is ideal for any three‑phase load that requires phase monitoring, including electric motors, air compressors, pumps, central air‑conditioning units, and distribution boxes used in industrial and commercial settings.

How does the device indicate a fault condition?

Each of the five built‑in LEDs corresponds to a specific condition: normal operation, phase loss, reverse phase, over‑voltage, and undervoltage. When a fault occurs, the associated LED illuminates, allowing operators to quickly identify and address the issue.

Can the GMR 32B be mounted on existing control panels?

Yes, the unit features a rail‑type base with standard M4 screw holes, enabling direct mounting on DIN rails or HT35 rails already present in most control panels, simplifying retrofits and new installations.

What is the recommended wire size for connecting the protector?

The main circuit connection should use insulating copper wire with a cross‑sectional area between 1.0 mm and 2.5 mm, suitable for single‑strand or stranded conductors, ensuring safe and reliable current flow.

Is there a warranty or support available for this product?

MUNEFE provides a manufacturer’s warranty covering defects in materials and workmanship, along with technical support to assist with installation, troubleshooting, and maintenance inquiries.
