It carries a continuous current rating of 25 A (flat across the full 40–70 °C ambient range, so no derating headache in a warm enclosure) and an insulation voltage of 800 V, which covers most 400/480 V industrial panels with headroom for 690 V systems.
Interrupting capacity — the real number for fault duty
At 240 V this breaker clears 242 kA symmetrical — that's a very high interrupting rating, typical for a large-frame MCCB on a high-fault utility feed. At 415/440 V it still holds 187 kA, and at 500 V it's 121 kA. The drop to 3.7 kA at 690 V tells you this is a 240–500 V part for most practical installations; if your system is 690 V, the available fault current must be under 3.7 kA, which is a niche case.
Dimensions are 181 mm high, 140 mm wide, 86 mm deep — a standard 4-pole MCCB footprint for 160 A frame size.
