Mars 83904 120V Single Phase Furnace Surge Protector (8in Leads)

Product Description

MARS 83904 is a 120V single-phase surge protection device for furnaces, air handlers, and other HVAC equipment. It uses thermally protected MOVs to provide line-to-neutral surge suppression with a 700V voltage protection rating (VPR) and 150V MCOV (L-N). The unit features a green LED status indicator, simple two-wire installation through a 1/2 inch knockout, and is rated for 50/60 Hz operation with a 10,000 amp short-circuit rating.

• Thermally protected MOV array providing L-N surge protection (VPR 700V, MCOV 150V)
• Simple two-wire hookup with 8 in. 12 AWG pre-stripped leads and fits 1/2 in knockout
• UL 1449 listed (Type 1/2), 50/60 Hz operation, 10,000 A short-circuit rating
