A2L COMPLIANT: Lovato Electric's electromechanical contactors have UL A2L certification, meaning they can be safely used with equipment that requires A2L (mildly flammable) refrigerants.
CHESAPEAKE, Va. — Lovato Electric’s electromechanical contactors — the BG Series mini-contactors, the BF Series contactors, and the DPBF Series Definite Purpose Contactors — are certified for use in refrigeration and air-conditioning equipment employing A2L (mildly flammable) refrigerants.
This certification gives HVAC and refrigeration OEMs a complete, drop-in, compliant switching solution as the industry transitions from R-410A refrigerant, a press release from Lovato said.
The certified product lines cover common loads found in compressor motor, fan motor, and electric heating elements in residential, light commercial, and commercial refrigeration applications. The portfolio includes:
• BG Series Mini-Contactors: Three-pole mini-contactors rated 6A to 12A (up to 7.5HP at 480V UL/CSA), available with AC, DC, and low-consumption DC coils.
• BF Series: Three- and four-pole contactors rated 9A to 25A (up to 15 HP at 480V UL/CSA).
• BF Series (BF26–38): Three- and four-pole contactors rated 26A to 38A (up to 30 HP at 480V UL/CSA), available with AC or DC coils.
• BF Series (BF40–94): Three- and four-pole contactors rated 40A to 94A (up to 60 HP at 480VUL/CSA), available with AC or AC/DC electronic coil options.
• BF Series (BF95–150): Three- and four-pole contactors rated 95A to 150A (up to 100 HP at 480V UL/CSA), available with AC or AC/DC electronic coil options.

• DPBF Series (Definite Purpose rated): Definite Purpose-rated versions of the BF Series contactors, designed for HVAC and refrigeration OEM applications requiring Definite Purpose ratings. Full load amp (FLA) ranges from 14A to 80A and locked rotor amp (LRA) ranges from 84A to 480A.
With the importing and manufacturing of R-410A equipment in the U.S. ended as of January 1, 2025, A2L certification is required for every arc-producing component in refrigerant zones. Each time an electromechanical contactor opens or closes, it generates an arc at the contact gap — a potential ignition source. A contactor without A2L certification is a non-compliant ignition risk regardless of its electrical rating. Lovato Electric’s contactors eliminate that risk.
Products carry UL LZGH2/8 certification under Certificate Number E93602, confirming compliance with UL 60335-2-40 and UL 60335-2-89 under UL and CSA standards. Specifying a LZGH2/8-certified electromechanical contactor enables UL to waive Annex FF leak simulation testing at the system level, reducing product development timelines by several weeks.
