It carries a rated breaking capacity of 25 kA at 415 V (class N), with a fixed thermal-magnetic trip unit — TM210 — set for a 20 A overload (Ir=20 A fixed) and a short-circuit pickup of 16 x In (Ii=16 x In). That 25 kA Icu at 415 V means this breaker can safely interrupt a fault current of up to 25,000 amps under a line-to-line fault on a 415 V system — without welding its contacts or exploding. For a panel fed by a transformer with that kind of available fault current, this breaker gives you the interrupting capacity you need to keep the arc flash energy contained and the rest of the gear alive.
Pricing and availability are confirmed at the time of quote against an RFQ. Because the part is current production, lead times are typically standard factory-to-distributor cycles; contact your sourcing desk for the exact number on your delivery window.
Where it fits — panel and load context
This breaker mounts into a standard IEC frame 160 panel footprint, with 4-pole connections for three-phase plus neutral (unprotected neutral). The fixed thermal setting (Ir=20 A) and fixed magnetic (Ii=16 x In) mean no field-adjustable dials — what you order is what you get. That suits a dedicated feeder or a fixed-load branch where you don't want someone turning up the trip setting later. The nut keeper kit is a small but welcome detail for OEMs building DC Power enclosures in China: it keeps the mounting hardware from wandering off during assembly or vibration in transit.
