The RECTORSEAL rect-96420 is a voltage range monitor designed to protect electrical equipment from damaging over-voltage and under-voltage conditions on the line. It operates across a dual-voltage range of 120 and 240 volts and is rated for 60 amps, making it suitable for a range of residential and light commercial electrical circuits. Licensed electricians and HVAC technicians install this device inline to provide continuous line monitoring and automatic protection for downstream equipment. When voltage strays outside acceptable limits, the unit responds to interrupt power and prevent equipment damage.
This voltage range monitor is used in applications where sensitive equipment must be protected from utility voltage fluctuations. Typical installations include residential HVAC systems, refrigeration units, motors, and other loads that are vulnerable to voltage swings. It is appropriate for both 120-volt and 240-volt single-phase circuits rated up to 60 amps, covering a broad range of residential and light commercial load types where consistent voltage supply is critical to equipment longevity and performance.
Designed as an OEM-style voltage protection device for single-phase 120-volt and 240-volt circuits rated up to 60 amps, typical of residential HVAC, refrigeration, and motor load applications.
Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. Disconnect and lock out power at the breaker before wiring the device into the circuit. Verify that the circuit voltage and amperage do not exceed the rated values of 120 or 240 volts and 60 amps before energizing. Do not bypass or override the monitor while equipment is running.
