Physical fit and mounting flexibility
The 3RT1076-2XJ46-0LA2: Dimensions: 225 mm depth, 214 mm height, 160 mm width. The contactor accepts screw fixing through a single 11 mm diameter hole. This covers most panel layouts without special brackets. Budget these gaps around the contactor in the enclosure layout for arc flash and cooling.
Wire termination and auxiliary contact ratings
This covers common control wiring sizes from 24 AWG to 14 AWG. An auxiliary switch is included (yes). These are the make/break limits for DC control circuits — derate for inductive loads per the application note. Switching frequency limits per duty cycle: AC-1 max 500 ops/h, AC-3 max 420 ops/h, AC-4 max 130 ops/h, DC-1 max 250 ops/h, DC-3/DC-5 max 200 ops/h. The AC-4 figure governs frequent plugging or inching applications.
Environmental range and coil data
Operating temperature: -40 to +70 °C. Storage temperature: -55 to +80 °C. The wide storage range suits unheated warehouses; the operating range covers most industrial enclosures. Coil rated voltage is 72 V DC. Dropout time at DC is 80 to 100 ms — this delay matters for sequencing logic where the contactor must drop out faster than the downstream device.
