The Schneider Electric GC1620F6 is a TeSys GC modular contactor — a 2-pole, 110 V AC 60 Hz controlled switching device rated for AC-7A and AC-7B utilisation categories. That means it's built for motor starting, resistive heating, and lighting circuits, not just general-purpose resistive loads. The AC-7A rating covers inductive loads up to 16 A, while AC-7B handles motor loads with a rated breaking capacity of 40 A at 400 V per IEC 61095. The control circuit voltage limits are tight: dropout between 0.2 and 0.75 Uc, pick-up between 0.85 and 1.1 Uc at 50 Hz — verify your control transformer regulation if you're running near the edge.
Integration notes
Mounting is clip-on to a DIN rail; the contactor's 17.5 mm width and 81 mm height let it sit in a standard 18 mm module slot. Screw clamp terminals on both control and power circuits accept up to 6 mm² solid or flexible cable (power) and 2.5 mm² (control). Tightening torque is 0.8 N.m for both — no special tooling needed. The IP20 finger-safe rating (per VDE 0106) applies when mounted in an enclosure; the contactor itself is not sealed against washdown. Heat dissipation is 1.3 W at 50/60 Hz, and power dissipation per pole is 0.65 W. In a densely packed panel, that's low enough to skip forced cooling for most layouts, but check your thermal budget if you're grouping multiple contactors side by side at full rated current.
