Product Description
LS Electric MC-85A-AC120 Metasol Contactor — 85A, 3-Pole, 120V AC Coil
The LS Electric MC-85A-AC120 is an 85A, 3-pole IEC contactor from the Metasol MC series with a 120V AC coil. Rated at 60 HP at 460V three-phase (85A AC-3 / 135A AC-1), the MC-85A-AC120 includes 2 Normally Open (NO) + 2 Normally Closed (NC) built-in auxiliary contacts and accepts both screw and lug power terminals. It mounts on 35mm DIN rail or panel backplate. LS Electric recommends the MC-85A as the direct replacement for the obsolete GMC-85 series. The compatible overload relay is the MT-95, which mounts directly to the contactor load terminals for a complete motor starter assembly.

Product Features
- 60 HP at 460V: The MC-85A-AC120 is rated for 60 HP at 460V three-phase (85A AC-3 / 135A AC-1). It is suited for larger motor starter applications including compressors, pumps, fans, conveyors, and industrial process equipment.
- 2 NO + 2 NC Built-In Auxiliary Contacts: The MC-85A-AC120 ships standard with two side-mounted auxiliary contact blocks, each providing 1 NO + 1 NC — for a total of 2 NO + 2 NC. This exceeds most same-frame IEC contactors, which typically include only 1 NO + 1 NC. Additional front-mount auxiliary blocks are available for expanded control requirements.
- Screw and Lug Power Terminals: The MC-85A-AC120 includes both screw terminals and lug-style connectors for the power circuit, providing flexibility for panel wiring with either wire end types or ring/fork lugs. Control circuit connections use screw clamp terminals.
- Direct GMC-85 Replacement: LS Electric designates the MC-85A as the manufacturer-recommended replacement for the obsolete GMC-85 series. The MC-85A is a direct functional and dimensional successor. Kent Electrical Supply also stocks the legacy GMC-85-AC120 while supplies last.
- MT-95 Overload Relay Compatible: The MT-95 thermal overload relay (63–85A, Class 10) mounts directly to the T1-T2-T3 load terminals of the MC-85A-AC120 for a complete, wiring-free motor starter assembly. Select the MT-95 current range based on your motor’s full-load amperage.
- 120V AC Coil: The AC120 designation specifies a 120V AC, 60 Hz operating coil — the standard US control voltage for industrial panel applications. The coil is integral (not field-replaceable) and connects via screw clamp control terminals. For 240V AC control circuits, order the MC-85A-AC240.
- DIN Rail or Panel Mount: Mounts on standard 35mm DIN rail or directly to a panel backplate via screw mount. Finger-proof terminal design standard.

Frequently Asked Questions
Is the MC-85A-AC120 a direct replacement for the GMC-85?
Yes — LS Electric designates the MC-85A as the manufacturer-recommended replacement for the obsolete GMC-85 series. The MC-85A is the current-production successor to the GMC-85, maintaining the same 85A AC-3 rating, 3-pole configuration, and DIN rail footprint. If replacing a GMC-85-AC120, order the MC-85A-AC120. Kent Electrical Supply also stocks the GMC-85-AC120 in legacy inventory while supplies last.
How many auxiliary contacts does the MC-85A-AC120 include?
The MC-85A-AC120 includes 2 NO + 2 NC auxiliary contacts built-in as standard. These are provided as two side-mounted auxiliary contact blocks, each containing 1 NO and 1 NC contact set. This is more than the single 1 NO + 1 NC pair found on most same-frame IEC contactors. The full catalog number reflecting this configuration is MC-85A-22-AC120, where the “22” indicates 2 NO + 2 NC.
What overload relay is compatible with the MC-85A-AC120?
The compatible overload relay is the LS Electric MT-95, which is rated 63–85A, Class 10. The MT-95 mounts directly to the load-side terminals (T1-T2-T3) of the MC-85A-AC120, forming a complete motor starter without additional wiring. Select the current range within the MT-95 family based on your motor’s nameplate full-load amperage. Call Kent Electrical Supply at 1-800-222-5129 for overload selection assistance.
What is the difference between the MC-85A-AC120 and the MC-85A-AC240?
The only difference is the coil voltage. The MC-85A-AC120 has a 120V AC, 60 Hz coil — standard for US industrial control panels. The MC-85A-AC240 has a 240V AC, 60 Hz coil. All other specifications — current rating (85A AC-3), HP rating (60 HP @ 460V), auxiliary contacts (2 NO + 2 NC), terminal type, mounting, and compatible overload (MT-95) — are identical.
Does the MC-85A-AC120 come with lug terminals or screw terminals?
The MC-85A-AC120 includes both screw terminals and lug-type connectors for the power circuit, providing wiring flexibility in the panel. Control circuit connections use standard screw clamp terminals. This dual terminal option is standard across the MC-85A family.
Does the MC-85A-AC120 qualify for same-day shipping?
Yes — the MC-85A-AC120 is a stocked item at Kent Electrical Supply’s warehouse in Emmaus, PA. Orders placed before 4:00 PM EST ship same business day. For bulk orders or the MT-95 overload relay, call us at 1-800-222-5129 or text your RFQ to 484-425-0652.
