It provides a safe and reliable way to connect or disconnect power to motors, ensuring smooth operation and protection against electrical faults. With a focus on energy efficiency and long service life, this contactor is a staple in motor control systems.
High Current Capacity: Available in models ranging from 9A to 630A, suitable for motors of various power ratings.
Silent Operation: Magnetic latching mechanism reduces noise during operation, improving workplace comfort.
Energy-Efficient Coil: Low-power consumption coils comply with IE3 efficiency standards, reducing energy costs.
Modular Design: Easy to install with removable auxiliary contacts and surge suppressors for flexible configuration.
IP20 Protection: Dust-resistant design with finger-safe terminals, enhancing operator safety.
The LC1 D Series is widely used in:
Motor Control Systems: Controls pumps, fans, compressors, and conveyors in manufacturing plants.
HVAC Systems: Switches power to air handling units, chillers, and boilers in commercial buildings.
Power Distribution: Used in switchboards and control panels for safe circuit management.
Renewable Energy: Controls generators and transformers in solar and wind power installations.
Q: What is the electrical lifespan for typical motor switching?
A: It offers up to 1,000,000 electrical operations at rated current, ensuring long-term performance.
Q: Can it be used with star-delta starters?
A: Yes, the contactor is compatible with star-delta starting systems, requiring appropriate auxiliary contacts for configuration.
Q: What voltage ratings are available?
A: It supports AC voltages from 24V to 690V, with coil voltages matching standard industrial frequencies (50/60Hz).
Q: Is there a version with built-in overload protection?
A: No, overload protection is typically provided by separate thermal relays, which can be easily mounted with the contactor.
