It carries a continuous current rating of 25 A and is rated for an insulation voltage of 800 V, so it handles standard 400/480 VAC industrial feeds with headroom. The interrupting capacity hits 242 kA at 240 V and 187 kA at 415 V — that SCCR lets it ride through high-fault scenarios without cascading upstream breakers.
At 415 V this MCCB clears 187 kA, and at 500 V it still handles 121 kA. Those numbers mean the breaker can be used in high-capacity switchboards where fault current runs high — think large motor control centers or transformer secondaries. The 690 V rating drops to 3 kA, so it's not the right choice for 690 V systems with high fault potential; that's a selectivity coordination call the panel designer has to make.
The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard SENTRON 3VA footprint that drops into a DIN-rail or screw-mounted enclosure without panel modifications.
Temperature derating and power loss
The 25 A rating holds flat from 40 °C all the way to 70 °C — no derating curve to calculate for warm enclosures.
