2600 A AC-1 Contactor for Resistive Loads
The 240 V AC 40-400 Hz coil draws 2500 VA inrush and 45 VA hold-in power.
Mounting and Integration — Plate Mount, Large Footprint
Mounting is plate-only — no DIN-rail option for a contactor this size. The footprint measures 519 mm wide by 382 mm high by 251 mm deep. Power connections use bar-type terminals accepting up to 100 x 10 mm busbars; control circuit connections are screw-clamp terminals for 1 to 4 mm² flexible or solid wire. Tightening torque on the power circuit is 58 N.m, so a torque wrench is expected during panel assembly.
Withstand and Breaking Capacity for Selectivity Studies
For coordination with upstream protection, the LC1F2600U7 carries a rated short-time withstand current (Icw) of 12,000 A for 10 seconds at 40 °C, stepping down to 4,000 A for 10 minutes. Rated breaking capacity is 3,900 A per IEC 60947-4-1. The associated fuse recommendation is 2,500 A gG at ≤ 440 V. These figures let a site electrical engineer confirm selectivity headroom without oversizing the feeder breaker.
Operating altitude is 3,000 m without derating. The contactor carries TH protective treatment for tropical environments. Standards compliance includes IEC 60947-4-1, EN 60947-4-1, UL 60947-4-1, and CSA C22.2 No 60947-4-1, covering the major North American and international regulatory jurisdictions.
