Rectorseal M83905 Surge Protector 208-230/240V

Product Description

The RECTORSEAL M83905 is a surge protector rated for 208-230/240 volt applications, designed to shield HVAC equipment and other electrical systems from damaging voltage spikes and transient surges. Installed at or near the equipment disconnect or load center, it absorbs excess voltage before it can reach sensitive components such as control boards, compressors, and variable-speed motors. Licensed electricians and HVAC technicians routinely specify surge protection on new installations and service calls to extend equipment service life and reduce callback rates.

The M83905 is suited for residential and light commercial HVAC systems operating on 208-230/240 volt single-phase power. Typical installation scenarios include condenser units, air handlers, heat pumps, and packaged rooftop equipment where voltage fluctuations from the utility grid or nearby loads present a risk to electronics and electromechanical components. It provides a straightforward add-on layer of protection during equipment installation or as a retrofit during a service visit.
