• The MC-18b Metasol-style magnetic contactor is built for high-performance switching. With a 40A Conventional Thermal Current (Ith) and a rated operational current of 18A (AC-3 at 440V), it provides robust power control for 3-phase motors and large industrial loads.
• Engineered to meet global standards, this contactor is UL Listed, CE, and CCC certified. These rigorous certifications ensure superior electrical safety, fire resistance, and durability, making it a reliable choice for professional contractors and industrial facilities.
• Designed for complex control systems, it features built-in 1 Normally Open (NO) and 1 Normally Closed (NC) auxiliary contacts (43/44 and 31/32). This allows for easy integration of status feedback, interlocking, or controlling secondary signaling circuits.
• Optimized for standard North American industrial control power, the 110V/120V AC coil ensures fast, chatter-free engagement. The high-quality electromagnetic core reduces vibration and noise, extending the mechanical life of the contactor.
• Features a compact footprint of 45mm (1.77") width and supports standard 35mm DIN rail mounting as well as screw mounting. Clear terminal marking (L1/L2/L3 & T1/T2/T3) and accessible wiring ports make installation and maintenance straightforward for any control panel.
