Schneider Electric RZM021FP Relay Protection Module

Product Description

The SCHNEIDER ELECTRIC RZM021FP is a relay protection module designed to safeguard relay coil circuits from voltage spikes, transients, and back-EMF generated during switching operations. Operating across a wide input range of 110-230 VAC and 110-230 VDC, this module mounts directly onto compatible relay sockets, providing integrated suppression without additional wiring. Its compact form factor measures 1.5 inches in length, 0.5 inches in width, and 0.3 inches in height, making it well suited for dense panel and control cabinet installations. Licensed electricians and control panel builders typically specify this type of protection module when relay longevity and downstream component protection are critical to system reliability.

This protection module is intended for use in industrial and commercial control panel applications where relay coils switch inductive loads. It installs directly on RGZ sockets compatible with the RXG series and RSZ sockets compatible with the RSB series. Its dual-voltage compatibility across both AC and DC supply ranges makes it a practical fit for mixed-voltage panel environments and machine control circuits where relay suppression is required at the socket level.

Key Features

• Wide coil voltage range: 110-230 VAC and 110-230 VDC in a single module
• Direct socket-mount design eliminates separate suppression wiring
• Compact size at 1.5 x 0.5 x 0.3 inches fits tight panel layouts
• Compatible with RGZ sockets for RXG series relays and RSZ sockets for RSB series relays
• Suppresses switching transients to protect coil contacts and adjacent components

Compatibility

Designed for direct use with RGZ sockets compatible with the RXG series and RSZ sockets compatible with the RSB series, as specified by the manufacturer.

Installation Notes

Installation of relay protection modules is typically performed by licensed electricians or qualified control panel technicians. De-energize and lock out the panel before handling any relay socket or module. The module snaps onto the relay socket — confirm the socket type matches the supported series before installation. Follow applicable NEC requirements for control circuit wiring and enclosure work.
