Power contactor, TeSys Giga, 3-pole (3NO), AC-3 <=440V 630A, standard version, 100…250V wide-range AC/DC electronic coil LC1G630KUEN

Advanced power contactor for demanding industrial applications

The TeSys Giga LC1G630KUEN power contactor is a three-pole device with 3NO main contacts and a rated operational current of 630A in the AC-3 category at voltages up to 440V, which translates to a power of 335kW at 400V. The design meets the requirements of the AC-4 category with a power of 315kW and the AC-1 category with a current of **1050A

Modular design and serviceability

The device features a modular design, which allows for easy replacement of key components without the need to dismantle the entire unit. The switching module (main contacts) and the control module can be replaced during simple maintenance tasks, significantly reducing installation downtime.

Power connections are made using bolt connections, while control circuits are equipped with modern push-in terminals. This connection system accelerates assembly and facilitates servicing. The device is mounted directly on a plate, and its compact dimensions (284 × 211 × 266 mm) allow for space savings in switchboards.

Advanced diagnostic functions and monitoring

The built-in Contact Wear Diagnosis (CWD) system is a standard feature of this model. The system continuously monitors the contact condition and provides information on normal and alarm states via an LED. This functionality enables predictive maintenance, allowing for the planning of service interventions before a failure occurs.

The mechanical durability of the device is up to 5 million cycles, guaranteeing long-term operation even in high-frequency switching applications. The maximum operating frequency reaches 500 cycles per hour in the AC-3 category.

Electrical and environmental parameters

The contactor is powered by a wide-range electronic coil with a control voltage of 100-250V AC/DC, eliminating the need to select different versions for different power systems. The low coil power consumption (15 VA in holding mode) translates into operational savings.

The device operates in an ambient temperature from -25°C to 60°C without derating rated parameters up to an altitude of 3000 m a.s.l. The IP2X protection rating on the front ensures safe operation in accordance with IEC 60529 and VDE 0106 standards.

Regulatory compliance and certificates

The contactor meets the requirements of international standards EN/IEC 60947-4-1 and EN/IEC 60947-5-1, holding CB Scheme, CCC, cULus, EAC, CE, and UKCA certificates. The product is compliant with RoHS/REACH directives and has Green PremiumTM status, confirming the best class of environmental parameters.
