It carries a continuous rated current of 25 A across the full ambient temperature range from 40 °C to 70 °C — no derating needed up to that ceiling, per the datasheet.
The interrupting rating is 242 kA at 240 V AC and 187 kA at 415 V AC. At 500 V it still holds 121 kA; at 690 V it drops to 3 kA. For a 480 V panel, the 187 kA figure at 415 V is the closest published point — that is well above typical utility fault currents for most industrial services. The 3 kA at 690 V is a niche value; this breaker is not intended for 690 V distribution where high fault current is expected.
Dimensions are 105 mm wide, 181 mm tall, and 86 mm deep. The 105 mm width is standard for a 3-pole MCCB in this frame size — it fits the same panel cutout and busbar spacing as other SENTRON 3VA2 devices.
