The L&T MC31ANX2200 is a commercial-grade Over Load Relay designed to protect three-phase AC electric motors from continuous overcurrent conditions, thermal degradation, and mechanical stalling. It operates as a L&T industrial protection relay, optimized for severe duty switching cycles, continuous monitoring, and effective thermal replication curves. The device is engineered to comply with strict international benchmarks such as IEC/EN 60947-4-1, UL, and CSA standards, making it fully ready for integration into global power grids operating at both 50Hz and 60Hz. Procurement managers can find this authorized switchgear with global shipment support on Electrihub.com.
The L&T MC31ANX2200 Over Load Relay continuously monitors phase currents via precisely calibrated internal elements (bimetallic strips or advanced electronic current transformers). In the event of a phase failure or single-phasing condition, the relay triggers an accelerated differential trip response to prevent rapid motor winding insulation breakdown. This action mechanically shifts the auxiliary contact block, opening the contact to break the control circuit coil and closing the contact to signal a system fault, ensuring complete protection across complex global automation networks.
The L&T MC31ANX2200 is physically and electrically engineered for direct plug-in mounting to matching L&T power contactor frameworks, optimizing panel space and eliminating unnecessary control wiring. It is certified for both Type 1 and Type 2 coordination schemas under short-circuit conditions when combined with appropriate molded case circuit breakers (MCCBs) or high-capacity fuses. For independent installation profiles, standalone DIN rail or panel baseplates are supported, providing global panel builders on Electrihub with maximum engineering flexibility.
The L&T MC31ANX2200 features a front-mounted current adjustment dial that allows commissioning engineers to set the precise trip threshold matching the motor's nameplate Full Load Current (FLC). The device features a user-configurable selection switch for Manual or Automatic reset modes; Manual mode requires an intentional field reset after diagnosing the overload fault, while Automatic mode allows the bimetallic components to self-cool and automatically restore the control path. Additionally, an integrated mechanical trip indicator enables swift diagnostic troubleshooting to minimize operational downtime.
Sourcing the L&T MC31ANX2200 Over Load Relay via Electrihub.com provides international industrial buyers with guaranteed product authenticity, manufacturer warranty support, and full technical datasheet compliance. Electrihub.com is optimized for global enterprise supply chains, providing competitive wholesale commercial pricing, transparent export-ready compliance documentation, bulk order capability for major infrastructure projects, and specialized engineering support to ensure seamless component coordination across all international projects.
The L&T MC31ANX2200 is a high-grade Over Load Relay engineered primarily to protect three-phase AC electric motors from damaging thermal overloads, prolonged stalled rotors, and phase imbalances. As detailed in its technical specifications, this relay operates as a L&T industrial motor protection thermal overload relay, optimized for Indian power conditions, agricultural pump starters, and motor control centers (MCCs). It is an essential component for motor control centers (MCCs) and automation panels across India, and can be procured directly with full manufacturer warranty on Electrihub.
The L&T MC31ANX2200 Over Load Relay utilizes internal bimetallic strips calibrated to bend under continuous overcurrent, heating up until they mechanically actuate the auxiliary trip contacts (95-96 NC and 97-98 NO). Additionally, it features differential tripping/travel mechanisms that provide accelerated tripping in the event of a single-phasing or phase failure condition. This prevents severe motor winding burnouts, making the MC31ANX2200 exceptionally reliable for unpredictable power grids in Indian industrial zones.
The L&T MC31ANX2200 is structurally and electrically optimized for direct plug-in mounting to matching L&T power contactors (such as the standard industrial starter ranges), creating a compact and rigid direct-on-line (DOL) or Star-Delta starter assembly. For standalone applications or independent panel mounting, it can be attached to an independent DIN rail or base plate adapter using standard screw terminals, ensuring flexible integration inside electrical panels sourced via Electrihub.in.
The L&T MC31ANX2200 features a front-accessible, adjustable dial that allows panel engineers to precisely set the current trip threshold matching the motor's full load current (FLC). It also includes a versatile user-selectable reset button supporting both 'Manual' reset (requiring field maintenance intervention after a fault verification) and 'Automatic' reset modes. A mechanical trip indication indicator is integrated to speed up diagnostics during maintenance cycles.
Electrihub is India’s leading B2B e-commerce platform for authorized industrial switchgear and automation components. When purchasing the L&T MC31ANX2200 Over Load Relay through Electrihub.in, buyers receive 100% genuine products, full compliance with GST tax invoicing, access to bulk commercial discount schemes, rapid logistics to major industrial hubs, and dedicated technical customer support for complex switchgear coordination challenges.
