Schneider Electric RXM021FP Relay Protection Module

Product Description

The SCHNEIDER ELECTRIC RXM021FP is a relay protection module designed to safeguard relay coil circuits in industrial and commercial control panel applications. It accepts a wide input range of 110 to 240 VAC or VDC, making it compatible with both AC and DC control voltage systems without requiring a dedicated module for each supply type. The RXM021FP mounts directly onto RPX or RXZ sockets, integrating cleanly into existing relay socket assemblies. Electricians and control panel technicians install this module to protect relay coils from voltage spikes, transients, and reverse polarity conditions that can degrade coil life or damage downstream components.

This module is suited for use in residential, light commercial, and industrial control panels wherever RPX or RXZ relay sockets are installed. It is commonly used in automation, HVAC control, and building management system panels where relay coil protection is required. Its broad voltage range simplifies inventory management on job sites with mixed AC and DC control circuits. Installation is straightforward due to the direct socket-mount design, eliminating the need for additional wiring hardware.

Key Features

• Wide operating range: accepts 110 to 240 VAC or VDC coil voltage
• Direct plug-in mount for RPX and RXZ relay sockets
• Protects relay coils from voltage transients and spikes
• Compact form factor fits standard relay socket footprints
• Single-unit packaging for precise inventory control

Compatibility

Designed for direct use with RPX and RXZ relay sockets as stated by the manufacturer.

Installation Notes

Installation is performed by licensed electricians or qualified control panel technicians. De-energize the control panel and verify zero voltage with a meter before handling any relay socket or protection module. The RXM021FP plugs directly onto the relay socket; no additional wiring is required. Follow applicable NEC guidelines for control circuit wiring and panel work when servicing the surrounding assembly.
