Plate-mounted, not DIN-rail; plan for the 438 mm width and 332 mm height footprint on the backplate. This is a heavy-current AC-1 machine — think resistive heating banks, large furnace elements, or distribution switching where the load current stays sinusoidal and inrush is low. ## Lifecycle reality — EOL phase, sourced to order If the application can tolerate a parametric substitute, a TeSys F contactor with the same pole count, coil voltage, and AC-1 current class is the starting point — but pinout, mounting hole pattern, and auxiliary wiring must be verified against the panel layout. The 238.6 mm depth and 438 mm width are the mechanical envelope to match. AC-1 at 1400 A is the headline number, but the short-time withstand (Icw) tells you what this contactor can survive during a fault: 8000 A for 10 seconds, 6000 A for 30 seconds, tapering to 2600 A for 10 minutes — all at 40 °C. That means upstream protection (fuse or breaker) must clear before the contactor's thermal limit is reached. The associated fuse recommendation is 1600 A gG at ≤ 440 V. Heat dissipation is 10 W holding (coil) plus 150 W per pole in AC-1 service — total 460 W dumped into the enclosure at full load. That drives ventilation or cabinet sizing; don't bury this in a sealed box without airflow. Operating time is 50–60 ms closing, 45–60 ms opening — consistent with a large DC-coil contactor. Not a fast-switching device; fine for resistive load on/off, not for high-speed cycling (max 600 cycles/hour at 55 °C). The LC1F1400GD carries IEC 60947-4-1, EN 60947-1, UL 60947-4-1, and CSA C22.2 No 60947-4-1 approvals — accepted in North American and European panels. Rated insulation voltage is 1000 V per IEC/UL, 1500 V per VDE 0110 group C. Impulse withstand is 8 kV, overvoltage category III. Protective treatment TH indicates tropicalized (humid/condensing environment) capability.","metaTitle":"LC1F1400GD TeSys F Contactor, 1400 A AC-1, 3P, 125 V DC","metaDescription":"LC1F1400GD TeSys F contactor, 1400 A AC-1, 3P, 125 V DC coil.
