Tightening torque 2 to 2.5 N·m (17.7-22.1 lbf·in). Mounting position any; the neutral pole switches internally, so no separate neutral bar connection needed on the load side.
Energy limiting class 3 means it restricts let-through energy during a fault — downstream equipment sees less thermal stress. Overvoltage category III suits fixed-installation distribution boards. IP20 with connected conductors is standard for enclosed panel mount; not rated for wet or dusty environments. Halogen-free and silicon-free construction matters where off-gassing or contamination could affect nearby electronics or clean-room processes.
