LS Electric MC Series AC Contactors

The LS Electric MC Series AC Contactors are a comprehensive range of IEC-rated electromechanical contactors covering 9 A to 800 A (AC-3 duty) for motor switching, capacitor bank control, and general power circuit switching in industrial control panels across Saudi Arabia. The MC series spans over 20 frame sizes from the MC-9 (9 A / 4 kW at 400 V) through the MC-800 (800 A / 400 kW at 400 V), providing panel builders with a single, consistent LS Electric contactor family that covers everything from small pump starters to large motor control centre cubicles in a single spare parts catalogue. All MC contactors are rated for AC-1, AC-2, AC-3, and AC-4 utilisation categories, and are pre-evaluated for compatibility with the full LS Electric range of thermal overload relays, auxiliary contact blocks, surge suppressors, and mechanical interlock accessories, enabling standardised assembly of star-delta starters, reversing starters, and DOL starters without compatibility concerns.

The MC series features silver alloy contacts with arc suppression chambers optimised for long electrical and mechanical life — rated for 10 million mechanical operations and up to 1 million electrical operations at AC-3, exceeding the IEC 60947-4-1 standard requirements by a significant margin. This extended operational life is especially valuable in Saudi Arabia's industrial facilities where high switching frequency, dusty environments, and limited maintenance access make contactor replacement a significant operational cost and downtime risk. The MC-9 through MC-100 range is available with 24 V DC, 48 V AC, 110 V AC, 220 V AC, and 380 V AC coil voltages to match any control circuit standard used in Saudi panel construction. Auxiliary contact blocks (NO, NC, early-make, late-break) snap directly onto the contactor body, allowing panel builders to add interlocking and monitoring contacts without additional wiring space.

In Saudi Arabia, LS Electric MC contactors are the single most widely stocked LS product by electrical panel builders and MRO distributors, reflecting their status as a cost-effective IEC-compliant contactor alternative to ABB A-series and Siemens 3RT contactors. Saudi Arabia's SEC-approved panel builders, maintenance departments at industrial facilities, and electrical contractors across the Kingdom use MC contactors in motor control centres, distribution boards, generator panels, and power factor correction systems. The competitive SAR pricing — typically 25–40% below European brand equivalents at the same IEC rating — drives their widespread adoption in both new construction and maintenance replacement markets throughout the Kingdom.

Razz Middle East maintains one of the largest LS Electric MC contactor stocks in Saudi Arabia, covering all common frame sizes (MC-9 through MC-150) and coil voltages for immediate supply. We offer quantity pricing for panel builder and project orders, and our team provides selection and cross-reference support to assist customers transitioning from ABB, Siemens, or Schneider contactors to LS Electric MC equivalents.
