LC1G2254KUEN | Schneider Electric TeSys Giga 4P Contactor 330A

LC1G2254KUEN: High-Power Switching You Can Rely On

Downtime in a high-power circuit costs more than any spare part. The Schneider Electric LC1G2254KUEN, part of the TeSys Giga range, is a 4-pole power contactor built to switch demanding loads with confidence. With a 330 A AC-1 rating and a 100–250 V wide-band AC/DC coil, it replaces several coil-specific variants with one reliable unit.

This standard version carries four normally open (4 NO) power poles plus 1 NO + 1 NC auxiliary contacts. As a genuine Schneider Electric component, it delivers the repeatability that motor control, heating, and DC switching applications demand.

Key Technical Specifications

• Protection: IP2X front face with shrouds

Why the Wide-Band Coil Matters

The 100…250 V AC/DC coil is the standout feature. One part number covers control voltages from 100 V to 250 V, in either AC or DC. That simplifies inventory and reduces the risk of installing the wrong coil variant. Built-in bidirectional peak limiting keeps inrush controlled at 540 VA (AC) or 380 W (DC), while hold-in consumption drops to 12.4 VA or 7.8 W.

Applications Across Heavy Industry

• Motor control centers: The 225 A AC-3 rating at ≤440 V suits large motor starting and stopping where reliability is critical.
• Resistive heating and DC loads: The 330 A AC-1 rating at ≤1000 V AC and ≤460 V DC supports high-current heating banks and DC circuits.
• Power distribution switching: With 2050 A breaking capacity at 440 V, the LC1G2254KUEN handles demanding switching duties in panels and switchgear.

Installation and Setup

Mount the contactor on a plate using the 35 mm connection pitch. Power connections accept 25 x 6 mm busbars or 185 mm² lugs-ring terminals, tightened to 18 N·m. Control wiring uses push-in terminals for 0.2…2.5 mm² conductors, with or without cable ends. The IP2X front face with shrouds protects against finger contact.

Operating temperature spans -25…60 °C, with permissible ambient around the device from -40…70 °C at Uc. Closing time is 40…70 ms; opening is 15…50 ms. Maximum operating rate reaches 600 cycles/hour in AC-3.

Reliability and Maintenance

TeSys Giga contactors are engineered for long service. The LC1G2254KUEN offers 8 million mechanical cycles and a B10d of 400,000 cycles with nominal load (EN/ISO 13849-1). Periodic inspection of terminal torque, contact wear, and coil operation keeps performance predictable. In dusty or vibrating environments, check mounting security and connection tightness at scheduled intervals.

Selection and Compatibility

The LC1G2254KUEN conforms to EN/IEC 60947-4-1 and 60947-5-1, with CB Scheme, CCC, cULus, EAC, CE, and UKCA certifications. Before ordering, confirm your application's utilisation category, coil voltage, and pole configuration.
