What this MCB carries
At 400 V AC it interrupts 30 kA per IEC 60947-2, with a DC rating of 15 kA at 72 V and a UL 1077 / CSA 22.2 No. 235 interrupting capacity of 5 kA. The D-curve means the magnetic trip activates at 10–20× rated current, so it holds through the inrush of a small motor or transformer bank without nuisance tripping. The 76 mm depth leaves clearance behind a standard 100 mm deep gland plate. IP20 with conductors connected; touch protection built in.
Integration notes
The sealable option (lockable toggle) lets the panel builder lock out a circuit for lockout/tagout without an external hasp. Ambient range -40 °C to 75 °C covers cold storage and hot roof-top enclosures; humidity derating applies above 55 °C (max 95% RH at 55 °C, tapering to 35% at 75 °C).
