The Schneider Electric TeSys GC1611J5 is a modular contactor — a 2-pole (2P) device with a 12 V AC 50 Hz control coil, designed for switching motor, heating, and lighting loads under utilisation categories AC-7A and AC-7B. The 12 V AC coil is a specific voltage variant within the TeSys GC family, so verify your control transformer taps or PLC relay output matches that AC supply before specifying.
The AC-7A and AC-7B utilisation categories define the switching duty: AC-7A covers lightly inductive loads like small motors and fans, while AC-7B covers resistive loads like heating elements and lighting. Electrical durability is rated at 100,000 cycles under both AC-7A and AC-7B, with mechanical durability at 1,000,000 cycles, so it's built for moderate-cycle applications like HVAC contactors or lighting contactor panels, not high-speed machine cycling. The control coil draws 15 VA inrush at 50 Hz (at 20 °C) and dissipates 1.3 W at 50/60 Hz. The drop-out voltage is 0.2 to 0.75 Uc, and the operational range is 0.85 to 1.1 Uc at 50 Hz below 50 °C — so the coil will hold in reliably down to about 10.2 V AC and drop out below about 2.4 V AC, which is a wide hysteresis typical for AC contactors. The operating time is 10 to 25 ms opening and 10 to 30 ms closing, fast enough for most lighting and motor control sequences.
Mounts via clip-on to a standard DIN rail (35 mm). The 17.5 mm width (one 18 mm module) means it takes up minimal rail space — useful when packing multiple contactors or relays into a lighting control cabinet or a small motor control centre. The IP20 finger-safe rating (per VDE 0106) applies when mounted in an enclosure; IP40 in an enclosure. Tightening torque is 0.8 N.m for both power and control terminals — a common value, so no special tooling needed. Mechanical robustness is specified for shocks up to 10 Gn (contactor open) and 15 Gn (closed), and vibrations up to 2 Gn (open) and 3 Gn (closed) across 5 to 300 Hz — adequate for industrial panel environments but not for direct machine mounting on high-vibration equipment.
