Product Description
LS Electric MC-85A-AC240 Metasol Contactor — 85A, 3-Pole, 240V AC Coil
The LS Electric MC-85A-AC240 is an 85A, 3-pole IEC contactor from the LS Electric Metasol series, rated for 40 HP at 230V and 60 HP at 460V three-phase (85A AC-3 / 135A AC-1). It comes factory-installed with two side-mounted auxiliary contact blocks (2 NO / 2 NC total) and offers both screw and lug terminal connections. The coil operates on 240V AC (50/60 Hz). The MC-85A-AC240 is the authorized replacement for the obsolete LS GMC-85 series contactor. The MT-95 series thermal overload relay mounts directly to the contactor for complete motor protection.

Product Features
- 2 NO / 2 NC Auxiliary Contacts Included: The MC-85A-AC240 ships standard with two side-mounted auxiliary contact blocks — one on each side — each containing 1 NO and 1 NC contact. Total: 2 NO / 2 NC at no extra cost, providing immediate control and signalling capability for motor starter interlocking and feedback.
- Screw and Lug Terminal Options: Unlike the smaller MC-32A (screw terminals only), the MC-85A-AC240 provides both screw clamp terminals and lug terminal connections for the power circuit. This accommodates a wider range of wire sizes (AWG 8–0) and installation methods common in larger motor control panels.
- Authorized GMC-85 Replacement: LS Electric designates the MC-85A as the manufacturer-recommended replacement for the discontinued GMC-85 contactor series. The MC-85A is an exact electrical and dimensional replacement — existing accessories, overload relays, and panel cutouts from GMC-85 installations are compatible with the MC-85A.
- Direct-Mount MT-95 Overload Relay: The LS Electric MT-95 series thermal overload relay mounts directly to the bottom of the MC-85A-AC240 for complete motor protection. Available current ranges from the MT-95 cover 9A to 100A — select the range to match your motor’s full-load amperage. The MT-95 is compatible with the MC-75A, MC-85A, and MC-100A contactor frames.
- High Durability: The Metasol MC-85A is designed for 12 million mechanical operations and 2 million electrical operations rated life. The sealed structure eliminates arc flash exposure and provides improved environmental immunity for demanding industrial applications.
- LS Electric Brand: LS Electric (formerly LSIS / LS Industrial Systems) is a major South Korean electrical manufacturer with 60+ years of history. The Metasol MC series is LS Electric’s flagship IEC contactor line, offering cost-competitive performance at ratings comparable to Schneider Electric LC1D and Eaton XTCE contactors.
- Global Certifications: UL 508 Listed, CSA Certified, IEC 60947-4-1 compliant, CE marked.

Frequently Asked Questions
Is the MC-85A-AC240 a direct replacement for the GMC-85?
Yes — LS Electric designates the MC-85A as the manufacturer-recommended replacement for the discontinued GMC-85 series. The MC-85A shares the same electrical ratings, dimensional footprint, and accessory compatibility as the GMC-85. Any overload relays or auxiliary contacts from GMC-85 installations will work with the MC-85A without modification. Select the AC240 variant to match a 240V AC coil GMC-85 installation.
What overload relay is compatible with the MC-85A-AC240?
The LS Electric MT-95 series thermal overload relay mounts directly to the bottom load-side terminals of the MC-85A-AC240. The MT-95 is available in current ranges from 9A to 100A and is compatible with the MC-75A, MC-85A, and MC-100A contactor frames. Select the MT-95 range that covers your motor’s nameplate full-load amperage. Call us at 1-800-222-5129 for overload selection assistance.
How many auxiliary contacts does the MC-85A-AC240 include?
The MC-85A-AC240 includes two side-mounted auxiliary contact blocks as standard — one on each side — each with 1 NO and 1 NC contact. Total standard configuration: 2 NO / 2 NC. Additional front-mounted or side-mounted auxiliary blocks can be added for more signalling circuits if needed.
What is the difference between the MC-85A-AC240 and the MC-85A-AC120?
The MC-85A-AC240 and MC-85A-AC120 are identical in every specification except the coil voltage. The AC240 has a 220/240V AC coil; the AC120 has a 110/120V AC coil. All other ratings — 85A AC-3, 60 HP @ 460V, 2 NO/2 NC auxiliary contacts, screw/lug terminals, and MT-95 overload compatibility — are the same. Always match the coil voltage to your control panel’s control circuit voltage.
What wire size does the MC-85A-AC240 accept?
The MC-85A-AC240 power terminals accept wire sizes from AWG 8 to AWG 0 (both solid and stranded copper conductors). The screw terminal and lug terminal options accommodate different wiring methods used in larger motor control panels. Control circuit (coil) terminals accept smaller gauge wire typical for control wiring.
Does the MC-85A-AC240 qualify for same-day shipping?
Yes — the MC-85A-AC240 is a stocked item at Kent Electrical Supply’s warehouse in Emmaus, PA. Orders placed before 4:00 PM EST ship the same business day. For bulk orders or questions about other MC-85A coil voltage variants, call us at 1-800-222-5129 or text your RFQ to 484-425-0652.
