Product details

Mounts on a backplate in either horizontal or vertical orientation, flat on the back. The 108 mm width and 137 mm height fit standard panel layouts. Connection terminals accept compression lugs or busbars from the front on both line and load sides. Neutral is on the left. The IP40 enclosure and IK07 impact resistance suit indoor panel environments — no washdown rating, so keep it inside the cabinet.

Frequently asked questions

What is the closest pin-compatible alternative to C11H4TM040B in this component family?

Within the ComPacT NSXm range, the primary difference is the trip unit rating. A 63 A frame (NSXm 63H) shares the same physical footprint and terminal layout; the trip unit rating determines the continuous current. No pin-compatible alternative with a different trip technology is listed for this frame.
