RectorSeal 96420 RSH-VRM60A Voltage Range Monitor 120/240V 60A Over/Under Voltage Protection

The RectorSeal RSH-VRM60A (96420) is a voltage range monitor designed to protect electrical equipment — including air conditioners, heat pumps, and other HVAC systems — from damaging over-voltage and under-voltage conditions. By continuously monitoring line voltage and automatically disconnecting loads when unsafe levels are detected, this unit helps prevent costly damage to circuit boards and motors.

Fully field-programmable without a laptop or special tools, the RSH-VRM60A supports 120/240V single-phase systems and handles loads from 15 to 60 amps via 60-amp double-pole capacity magnetic latching relays. The programmable voltage cutoff range spans 90V to 300V, providing broad protection across a wide variety of applications.

Key Features:

• Over/Under Voltage Protection — Automatically disconnects loads when voltage falls outside the programmed safe range
• Adjustable Cutoff Delay — Over/under voltage cutoff delay adjustable from 0.5 to 60 seconds to prevent nuisance trips
• Adjustable Load Restore Delay — Controlled power restoration delay adjustable from 1 to 600 seconds after voltage stabilizes
• 60A Double-Pole Capacity — Magnetic latching relays handle loads from 15 to 60 amps for maximum reliability
• Programmable Voltage Cutoff Range — Fully programmable from 90V to 300V
• Event Logging — Internal memory stores up to 300 events; all settings are retained when power is lost
• LCD Digital Display — Large, easy-to-read display with dual red and green LED diagnostic indicators
• 35mm DIN-Rail Mounting — Easy panel installation via standard DIN-rail receiver
• Field Programmable — No laptop or programming tool required for setup

The RSH-VRM60A is an ideal voltage protection solution for residential and commercial electrical systems, particularly where sensitive HVAC equipment requires reliable safeguarding against power fluctuations.
