OEM LC1D Series AC contactor 50/60Hz 660V Manufacturers, Factories

The LC1D Series AC contactor operates in AC 50/60Hz circuits up to 660V, handling rated currents up to 300A at 380V (AC-3 category). Designed for long-distance circuit making/breaking and frequent motor starting, it pairs with thermal overload relays to protect against overloads. Features include a compact modular design, high mechanical/electrical life (up to 20M/2M cycles), multiple connection types (screw/Everlink/spring terminals), and compatibility with auxiliary contacts, delay heads, or mechanical interlocks. Suitable for industrial, infrastructure, and building applications.
