Product details

The 3-pole configuration (3P) suits three-phase distribution panels. The thermal-magnetic trip unit (TM-D) is a fixed-setting type, not adjustable in the field, so the 16 A rating must match the protected circuit's design current.

Deployment context

Mounts on a backplate (DIN rail compatible via the 9-module pitch) in a distribution panel or enclosure. The IP40 front face and IK07 impact resistance suit indoor panel installations where tools or panels may be bumped. Connection is via compression lugs or busbars, front-accessible from both top and bottom. The 35 mm connection pitch with spreaders (27 mm without) matches standard busbar systems. The toggle control and green flag for auxiliary contact presence give clear local status.
