Three modular-width units (54 mm wide, 90 mm tall, 76 mm deep) snap onto standard DIN rail. Mount it in any position — no orientation restrictions. Sealable, halogen-free, silicon-free — matters for installations with strict material compatibility requirements or where sealable breakers are needed to prevent tampering.
Electrical ratings and application note
Maximum operating voltage is 440 V AC multi-phase. DC rating is 72 V maximum — usable in some DC sub-circuits but limited to that voltage. Energy limitation class 3 means it lets through less fault energy than class 1 or 2 devices, which helps protect downstream equipment. Mechanical life is 10,000 switching cycles — typical for an MCB; not a device you'd cycle daily as a switch, but fine for occasional manual isolation.
Sourcing and compliance
This is an active-production part under the SENTRON brand. No end-of-life notice, no successor to track.
