Three poles, 3 width units (54 mm), and it snaps onto a DIN rail — standard panel integration.
The D-curve (tripping characteristic D) means the magnetic trip fires at 10–20× rated current — so for this 10 A breaker, instant trip between 100 A and 200 A. That's the right window for motor circuits or other inductive loads that draw a short high surge on energization. On a 400 V industrial panel with a transformer upstream, that's a solid safety margin. The magnetic-only design (no bimetal) also means no thermal derating from ambient heat — it's rated for -35 to +70 °C ambient, and the trip point stays consistent across that range.
Terminal and wiring detail
Combined terminals top and bottom, so you can feed through or loop out without extra connectors. Sealable, halogen-free, silicon-free — relevant for food processing or clean-room panels where outgassing matters.
