The grey (RAL 7016) enclosure carries IP40 protection and IK07 impact resistance — suited for panel-mount in clean, dry environments where occasional tool contact is expected.
If your panel runs hotter, you'll need to derate — the TM-D trip unit is temperature-sensitive, so a 50 °C cabinet might drop the usable current to roughly 72 A. For a 400 V distribution board with a prospective short-circuit current under 16 kA, this breaker clears the fault without upstream damage. The 4-pole (4P) configuration switches all four poles — three phases plus neutral — making it suitable for TN or TT systems where the neutral needs protection.
This MCCB mounts on a backplate via its 9-module pitch (12 modules at 9 mm each = 108 mm wide). Connection is front-facing on both line and load sides, using Everlink lugs that accept 2.5 to 95 mm² rigid or stranded aluminium/copper cable (70 mm² flexible copper). That's a wide wire range — good for both feeder and subfeed applications. The breaker sits flat on the backplate, horizontal or vertical, so panel layout is flexible. Pollution degree 3 (IEC 60664-1) means it's rated for conductive pollution environments typical of industrial control panels.
