DUCTED/DUCTLESS A/C AND HEAT PUMPS
Voltage Protection Elevated
The RSH Voltage Range Monitoring (VRM) devices protect equipment from damage by overseeing voltage levels, with programmable cutoff ranges from 90V to 300V. They can also store data on up to 300 events, providing a comprehensive record for analysis and response. The RSH-50 VRMDC KIT model combines the VRM60A, RSH-50, & 60A disconnect breaker in a NEMA 3R enclosure, for an all-in-one equipment solution.
Recommended for all single phase 120/240V HVACR Equipment (AC, heat pumps, mini-split applications).
