It's sealable, halogen-free, and silicon-free — that last one matters if you're potting or conformal-coating a panel and don't want any silicone outgassing fouling contacts downstream.
Mounting and fit — what the DIN rail sees
Width is 36 mm — exactly two modular units — so it clips onto a standard DIN rail without eating extra space. Depth is 76 mm, height is 90 mm. Installed depth from the rail face is 70 mm, which leaves clearance behind most panel gland plates. Mounting position is any; the quick-assembly system clicks onto the rail without tools. Temperature derating matters: at 40 °C it's still able to carry 42.27 A continuous, at 50 °C it drops to 39.33 A.
Lifecycle and compliance — what procurement needs to know
It's designed to IEC / EN 60898-1 and IEC / EN 60947-2 / UL1077, so it carries the dual label for domestic and industrial approvals.
