Electronic Products - Restraint Interface Module

The RIM32 Restraint Interface Module is used to interface the restraint signals between various Square D Micrologic® circuit breakers, Micrologic ground-fault modules, and GC-100 ground-fault protection systems.

The restraint interface module operates on either 120 or 240 Vac, 50/60 Hz. The module is protected by a 1/4 A fuse.

Allowable ZSI combinations are shown in Table 3.82. (Series numbers for current design circuit breakers end in B, for example NE Series 3B.) For double-ended or larger systems, or systems which contain devices from different columns in Table 3.82, contact your local Sales Office for combination information.

If more inputs or outputs are needed, another restraint interface module is necessary. Contact your local Sales Office for information on multiple module installations.

The maximum distance between devices is 1000 ft. (305 m).

RIM Requirements

The Restraint Interface Module (RIM) is used to allow zone-selective Interlocking communications between circuit breakers with Micrologic® Series B trip units or
Micrologic® #.Ox trip units, Compact® STR53 trip units, Masterpact® STR58 trip units, Federal Pioneer USRC and USRCM trip units, and Square D GC series ground-fault relays.

Upstream circuit breakers with Micrologic 3.0A, 5.0A 5.0P, 5.0H, 6.0A, 6.0P, and 6.0H trip units can receive up to 15 input signals without requiring a restraint interface module. If the number of input signals exceeds 15, then a RIM is required. Contact your local Sales Office for RIM requirements.

The restraint interface module operates on either 120 Vac/24 Vdc, or 240 Vac/24 Vdc, 50/50 Hz.

The maximum distance between devices is 1000 ft. (305 m)
