The breaking capacity is where this part earns its keep: 100 kA Icu at 110-130 V AC, 50 kA at 220-240 V AC, 30 kA at 380-400 V AC, and 20 kA at 440 V AC — all per IEC 60947-2. That's a lot of fault-current headroom for a 30 A frame, so it handles high-available-fault panels without cascading upstream. On the DC side it manages 10 kA Icu at 125 V DC (1P) and 250 V DC (2P).
It complies with EN/IEC 60947-2, EN/IEC 60947-1, GB/T 14048.2, and JIS C8201-2-2. The IP20 finger-safe enclosure and IK07 impact resistance mean it's suited for panel-mount where incidental contact and light mechanical knock are expected.
Backplate-mounted with a fixed connection pitch of 25 mm. The toggle actuator gives positive contact indication, so you can see the state at a glance without relying on aux contacts. Dimensions are 130 mm high, 100 mm wide, 60 mm deep — a compact footprint for a 4-pole 30 A MCCB with this interrupting rating.
Environmental limits and durability
Mechanical durability is 13,000 cycles — that's the expected life under no-load switching; the electrical life will be lower under load and depends on the fault and switching frequency. The 690 V AC rated insulation voltage gives margin above the 550 V AC operational maximum.
