The main circuit uses spring-loaded terminals accepting 2x (0.25 to 2.5 mm²) solid or stranded conductors, or 2x (24 to 14 AWG). This eliminates the need for screwdriver torque checks during panel assembly — a time-saver on high-density DIN rails. Rated for motor loads: 4.5 kW at 500 V and 5.5 kW at 690 V (AC-3 duty). If your application involves frequent reversing or jogging, the AC-4 figure governs contact life, not the AC-3 number. DC switching capability is specified per voltage: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V. These are resistive-load values; inductive DC loads (brake coils, solenoid valves) require a free-wheel diode across the load to prevent contact welding. The coil itself draws 3.3 W closing and 3.3 W holding — a constant-power coil that stays cool in continuous duty. Type 1 coordination allows a 35 A gL/gG fuse. Type 2 means the contactor remains usable after a fault (no welding of main contacts), while Type 1 allows contact replacement. For critical process lines, spec the Type 2 fuse. ## Panel Integration and Environmental Limits At 45 mm wide, 60 mm tall, and 73 mm deep, the 3RT1016-2BE42 occupies a single 45 mm DIN-rail module. The IP20 front protection means it is safe for finger contact in enclosed panels; the terminal area is also IP20.
