Restraint Interface module (RIM) 120 V AC

The Restraint Interface Module (RIM) is designed to support zone-selective interlocking (ZSI) schemes in low-voltage power distribution systems. Operating at 120 V AC, it coordinates with protection devices to improve fault discrimination and reduce system downtime.

Key Features:

  • Function: Enables Zone-Selective Interlocking (ZSI) between upstream and downstream protection devices

  • Operating Voltage: 120 V AC

  • Application: Ideal for use in installations requiring fast, coordinated fault clearing (e.g. switchboards, MCCs, and panelboards)

  • Compatibility: Works with circuit breakers and trip units designed to support restraint signalling protocols

  • Design: Compact and easy to integrate within existing protection schemes

The RIM helps enhance safety and selectivity in electrical systems by allowing only the device nearest to a fault to trip, minimising disruption to the rest of the system.
