TeSys Giga 4-pole contactor – active, multi‑region compliant
The LC1G1154EHEN: Rated for AC-3 motor loads and AC-1 resistive duty, with a maximum operating rate of 600 cycles/hour in AC-3 and 300 cycles/hour in AC-1. Mechanical durability 8 million cycles — no routine replacement needed over a typical machine life. Power dissipation per pole: 10 W at AC-1 (250 A Ith) and 3 W at AC-3 (115 A Ith).
Cross‑border compliance for a genuine part
Protective treatment TH (tropicalization) is standard on this unit, so it's ready for humid or corrosive environments out of the box. The IP2X front face with shrouds (per IEC 60529 and VDE 0106) adds operator touch protection in unsealed cabinets.
Mounting, connections, and coil specs
Plate‑mount only – no DIN‑rail adapter on this frame. Dimensions: 7.6 x 5.6 x 7.6 in (193 x 143 x 193 mm). Power circuit terminals accept busbar up to 25x6 mm or lugs up to 185 mm². Control circuit uses push‑in terminals (0.25–2.5 mm² flexible or solid). Tightening torque for power connections is 159.3 lbf·in (18 N·m). Control circuit voltage: 48–130 V AC/DC; operational limits 0.8 x Uc min to 1.1 x Uc max, drop‑out 0.1 x Uc max to 0.45 x Uc min at ≤60 °C. Inrush power 445 W DC. Auxiliary contact composition: 1 NO + 1 NC built in. If more aux contacts are needed, the TeSys Giga add‑on blocks fit the same mechanical interface – order separately.
Duty ratings and application fit
Associated fuse recommendations: 125 A aM, 315 A gG, or UL Class J up to 300 A at ≤600 V. The contactor itself offers vibration resistance: 2 gn open, 4 gn closed (5–300 Hz); shock 10 gn open, 15 gn closed (11 ms). That's typical for general industrial panels; for rail or shipboard applications, check the broader TeSys Giga range for enhanced ratings.
