RectorSeal has added a voltage monitoring device (VMD) and two disconnect boxes pre-wired with surge protectors to its RSH Series of surge protective devices (SPD) designed specifically for HVAC/R systems. The new RSH-60 VMD is a combination voltage monitor and SPD for single phase, 120/240V air conditioning and heat pumps (not recommended for mini-splits). During utility brownouts, voltage drops or other electric line disturbances, the RSH-60 VMD shuts down the HVAC/R condenser to protect the compressor motor and circuit boards from running on deficient voltage.
