Rectorseal 96415 RSH-50 Surge Protective Device 120/240V

Product Description

The RECTORSEAL 96415 RSH-50 is a Type 1 Surge Protective Device (SPD) built for single-phase, 120/240 VAC electrical systems. It guards air conditioning units, heat pumps, and ductless mini-split systems (DMSS) against transient over-voltage events and naturally occurring electrical surges. Protection status is indicated by a green LED mounted on the device, giving technicians an immediate visual confirmation that the SPD is active. The RSH-50 carries a limited lifetime warranty and is rated for outdoor installation under NEMA 4X enclosure standards, making it suitable for exposed equipment locations.

The RSH-50 is intended for residential and light commercial single-phase HVAC applications. Typical installations include split-system air conditioners, heat pumps, and ductless mini-split systems where surge protection is required at the equipment disconnect or service entrance. It is appropriate for installations where weather exposure is a factor, given its NEMA 4X rating. HVAC technicians and electricians install this device as part of equipment protection plans or as a replacement for failed surge protection on existing systems.

Key Features

• Type 1 SPD rated for 120/240 VAC single-phase systems
• Gas Discharge Tube (GDT) technology for long-lasting surge suppression
• TFMOV technology provides transient over-voltage clamping
• Green LED indicates active protection status at a glance
• NEMA 4X weather-rated enclosure for outdoor and exposed installations
• Limited lifetime warranty

Compatibility

Designed for single-phase 120/240 VAC air conditioning systems, heat pumps, and ductless mini-split systems (DMSS) requiring Type 1 surge protection.

Installation Notes

Installation is typically performed by a licensed electrician or HVAC technician in accordance with applicable NEC requirements for surge protective devices. Disconnect and lock out all power to the equipment before wiring the SPD. Follow the manufacturer wiring diagram and local code requirements for proper conductor sizing and grounding. Verify the green LED is illuminated after restoring power to confirm the device is functioning correctly.
