The C25R4TM160: This breaker mounts to a backplate — not a DIN rail — and can be installed horizontally or vertically flat on the back of the enclosure. The front-facing connections (both line and load sides) simplify busbar routing and cable entry in a panel layout. Neutral is on the left, and the toggle handle provides manual control. IK07 impact resistance handles the bumps of a working cabinet.
Durability and application notes
Mechanical durability is rated at 20,000 cycles; electrical durability varies by load — 20,000 cycles at 440 V at half rated current, 10,000 cycles at full rated current, and 5,000 cycles at 690 V. That's typical for a distribution breaker; if you're switching it daily under load, those numbers give you a rough service life estimate. The utilisation category A means it's not intended for frequent motor switching or high inrush loads — it's a distribution breaker, not a motor starter. Relative humidity range of 0 to 95% covers most indoor industrial environments.
