Its 25 A continuous rating and 4-pole configuration suit it for three-phase plus neutral circuits in commercial and industrial installations where you need coordinated overcurrent protection.
This MCCB carries a rated ultimate short-circuit breaking capacity (Icu) of 242 kA at 240 V AC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V. At typical 400 V-class distribution voltages, 187 kA is well above what most service-entrance or sub-distribution panels will see, so you have headroom for high-fault installations like large transformer secondaries or industrial mains.
The 4-pole footprint matches standard MCCB mounting patterns for panel or chassis installation. Rated insulation voltage is 800 V, and the operating temperature range is -25 °C to 70 °C, with storage from -40 °C to 80 °C.
