The EN figure is the standard for household and similar installations — adequate for most distribution boards.
Rated for -40 °C to 75 °C ambient, which covers unheated warehouses, outdoor enclosures, and the hot top of a panel above a drive section. IP20 with conductors connected, IP40 in the handle area: fine inside a sealed enclosure; don't leave the terminals exposed to dripping water.
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm number.
The installation depth is 70 mm — that's the dimension from the DIN-rail face to the back of the breaker, not counting the handle throw.
The SENTRON series carries CE marking and is designed to EN 60898 and IEC 60947-2. Halogen-free and silicon-free construction. For specific RoHS/REACH declarations, the manufacturer's documentation portal covers this order code.
