Physical fit and panel integration
Three modular-width units (54 mm wide, 90 mm tall, 76 mm deep) snap onto standard DIN rail. Installation depth is 70 mm behind the panel face. Mount it in any position — no orientation restrictions. IP20 with connected conductors, so it's fine inside a closed cabinet but not for wet or washdown zones. Rated for overvoltage category III and pollution degree 2 — standard for distribution panels in residential and light commercial infrastructure. 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
Breaking capacity is 6 kA per both EN 60898 and IEC 60947-2 at 400 V AC. That's enough for most residential and light commercial service entrances where the prospective fault current stays under 6 kA. 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. Sourced and quoted to order against an RFQ through independent distribution.
