RectorSeal launches new HVAC electrical protection devices

RectorSeal has introduced two new products to the RSH Series of surge protection devices (SPD) and voltage range monitoring (VRM) kits.

RectorSeal RSH Series devices have been designed to protect HVAC equipment from electrical surges, brownouts, and other voltage disturbances resulting from transient over-voltage and natural-cause surges.

“The RSH series is a preferred choice for HVAC technicians,” says the company. “Offering easy installation, proven performance, and an outstanding limited warranty, RSH Series products are weather-rated under NEMA 3R and can be installed within minutes to the outdoor disconnect electrical box.”

The RSH-VRM60A voltage range monitoring device is designed to support 120/240 single phase, 60 amp double pole capacity relays for loads of 15–60 amps. It can be used with ductless and ducted HVAC systems. Features include a voltage read-out screen, a large, easy-to-read LED digital display, and dual red and green LED diagnostic indicators. The RSH-VRM60A also has an over/under voltage cut-off device with an auto restore and push-button cut-off setpoint adjustments to cover a wide range of input voltages. A two-year limited warranty covers the device.

The RSH-50VRM Kit is a surge protector and voltage range monitor designed to support 120/240 single phase, 60 amp double pole capacity relays of 15–60 amps. According to RectorSeal, no laptop or programming tools are required, resulting in easy set-up, and the device is field programmable.

Features include an all-mode surge protector with gas tube and thermally fused (MOV) suppression technology. It has a large LCD digital display and dual red and green LED diagnostic indicators. A non-volatile memory retains all settings, and an event log is available when power is lost. More than 300 over/under voltage and power-loss events are kept in the resettable internal memory.

The RSH-50VRM Kit has adjustable mounting flanges for easy installation. It also has a heavy-duty hinged enclosure with dual latching mechanisms. NEMA 3R weather-resistant, rated for protection against rain, sleet, and snow, the device will not be damaged by ice formation, allowing for outdoor use.

A two-year limited warranty covers the voltage range monitoring device, and the surge protection device for single-phase has a limited lifetime warranty.

Both devices are RoHS compliant, UL listed and available from select RectorSeal distributors and representatives.
