Description

GLC3 AC Contactor is a high-performance industrial switching device designed for the remote making and breaking of circuits, as well as frequently starting and controlling AC motors. Engineered for reliability and safety, this contactor series is an essential component for modern automation systems, HVAC applications, and heavy-duty machinery. With a rated operating current range from 6A to 95A across 12 distinct specifications, the GLC3 offers a tailored solution for diverse power control requirements.

Robust Performance and Safety

Built to meet stringent international standards (IEC 60947-1 and IEC 60947-4-1), the GLC3 series ensures operational safety with a rated insulation voltage (Ui) of 690V and a rated impulse withstand voltage (Uimp) of 6kV. The housing and base are constructed from V0 rating flame-retardant materials, providing superior protection in harsh industrial environments. Its IP20 protection grade ensures safety against accidental contact, making it suitable for manual overload relay integration.

Flexible Configuration and Accessories

The GLC3 is designed for versatility. It supports both DIN rail and screw mounting, allowing for easy installation in various panel configurations. The system is highly modular, supporting a wide array of accessories to expand functionality:

PC Transparent Dust Cover: For added protection against environmental contaminants.
Auxiliary Contacts: Expandable via F1 (top mounting) and FC1 (side mounting) modules.
Time Delay: FY1 air delay head module for precise timing control.
Protection & Interlock: Compatible with FR1 mechanical interlocks and coil surge suppression modules.

Optimized for Heavy Duty Cycles

Whether for AC-3 (squirrel-cage motors) or AC-4 (inching and plugging) utilization categories, the GLC3 delivers consistent performance. It features a high electrical and mechanical lifespan, capable of handling up to 1200 operations per hour mechanically. The unit comes standard with built-in auxiliary contact features (1NO + 1NC configuration available), ensuring seamless integration into control logic circuits.
