Mounting and clearance — fitting it into the enclosure
The 3RT1364-6AP36: Clearance distances are 10 mm upwards, downwards, and to the side, and 20 mm forwards — these are the minimum air gaps to adjacent metalwork or other devices to avoid arc flash tracking and to allow heat dissipation from the coil. Overall dimensions are 196 mm height, 140 mm width, and 153 mm depth — the depth is the dimension that often catches panel builders when the enclosure backplate is tight against the gland plate.
Termination and auxiliary contacts
An auxiliary switch is included as standard, with two instantaneous contacts (NO/NC configuration not specified in the record, but the presence of the switch means the contactor can signal its state back to the PLC or annunciator without an add-on block).
