TeSys Deca contactor, 4P 4NO, 60 A AC-1, 110 V AC coil, 1NO+1NC built-in aux, IP20.
The Schneider Electric LC1DT60AF7 is a 4-pole TeSys Deca contactor rated 60 A AC-1 for non-inductive and resistive loads up to 440 V. It runs on a 110 V AC 50/60 Hz coil, connects power via EverLink BTR screw connectors, and includes a built-in 1 NO + 1 NC auxiliary block with a mirror-certified NC contact.
The EverLink BTR power connectors hold their torque through thermal cycling better than plain screw clamp terminals, which matters at 60 A where repeated heat-up and cool-down can loosen a standard terminal. Pick this 110 V AC coil when the panel control transformer runs that tap; move to the LC1DT80 frame only if the resistive load exceeds 60 A.
Lighting banks, heater circuits, and resistive-load distribution panels up to 60 A, including marine and offshore boards covered by the GL/DNV/LROS/RINA/BV society approvals. The EverLink terminals also suit panels with frequent maintenance disconnections.
