Price & Availability 30.76 USD （参考价 / est. market price） Basic Product Information 24V DC coil for integration with DC control circuits Compact design for space-saving installation in control panels High durability with mechanical and electrical life exceeding 1 million operations Complies with IEC and UL standards for global use Suitable for AC-3 and AC-4 utilization categories 18A rated current for reliable switching of motors and resistive loads Technical Specifications Version & Model Difference The LS MC-18A series includes variants with different coil voltages (e.g., 24V AC, 110V AC, 220V AC, 24V DC). The 24VDC version is specifically designed for DC control circuits, offering faster switching and lower coil power consumption compared to AC coil versions. There are no significant differences in mechanical construction or performance among the voltage variants. Application Scenarios HVAC systems: controlling compressors, fans, and pumps Refrigeration units: switching condenser and evaporator fans Motor control centers: starting and stopping three-phase motors Industrial automation: controlling conveyors, mixers, and other machinery Building management systems: lighting and power control Retrofit and replacement: direct replacement for failed contactors in existing panels Can the LS MC-18A 24VDC be used for motor starting? Yes, it is rated for AC-3 duty, making it suitable for starting and stopping squirrel-cage motors. What is the difference between the MC-18A and MC-18B? The MC-18A and MC-18B are similar in ratings, but the MC-18B may have different auxiliary contact configurations or coil options. Check the specific datasheet for details. Is the LS MC-18A 24VDC a direct replacement for other brands? It can replace contactors with similar specifications (18A, 24V DC coil) from brands like ABB, Siemens, and Schneider, but verify mounting and terminal compatibility. What is the coil voltage of the LS MC-18A 24VDC contactor? The coil voltage is 24V DC, suitable for DC control circuits.
