The Siemens 3VA1225-6GF42-0HC0 is a 4-pole moulded-case circuit breaker on the 3VA1 IEC frame, sized for 250 A continuous. Its class H breaking capacity — Icu=70kA at 415 V — means it can safely interrupt a fault current up to 70 kA without welding or rupturing, which is the rating needed for high-fault industrial mains where a standard 50 kA breaker would fail. The TM240 thermal-magnetic trip unit gives adjustable overload protection (Ir = 175…250 A) and short-circuit pickup (Ii = 5…10 × In), so you set the overload band to match the cable or load, not the breaker's maximum. The integrated shunt trip (STL) accepts 12-30 V DC or 24 V AC 50/60 Hz for remote emergency-off or supervisory tripping; the two HQ auxiliary switches report breaker position back to the PLC or status panel.
