Mars mars-83915 Surge Protection Device 120 240 Vac

Product Description

The MARS mars-83915 is a Type 1/2 surge protection device rated for 120/240 VAC single-phase systems operating at 50 or 60 Hz. Surge protection devices in this class are installed at the service entrance or distribution panel to clamp transient voltage spikes before they reach sensitive HVAC equipment, motors, and controls. The mars-83915 is designed for single-phase residential and light commercial electrical systems. Licensed electricians and HVAC technicians typically install this device during new system commissioning or as a retrofit to protect existing equipment from power surges caused by lightning strikes, utility switching, and load cycling.

This surge protection device is suited for single-phase 120/240 VAC applications commonly found in residential service panels and light commercial electrical distribution systems. It operates across the standard 50 Hz and 60 Hz utility frequencies, making it appropriate for domestic installations. Typical applications include protection of HVAC condensing units, air handlers, heat pumps, and associated control boards where transient overvoltage events pose a risk of equipment damage or premature component failure.

Key Features

• Type 1/2 rated surge protection suitable for service entrance and load-side panel installation
• Rated for 120/240 VAC single-phase systems
• Compatible with both 50 Hz and 60 Hz utility frequencies
