What the key ratings mean for fit
The C25F32D250: Breaking capacity is the main selector: 85 kA Icu at 240 V AC, 36 kA at 415 V AC, 35 kA at 440 V, 30 kA at 500 V, 22 kA at 525 V, and 8 kA at 690 V. The 20-minute thermal memory means the trip curve accounts for prior heating after a trip, preventing nuisance reclosing on a still-hot conductor. Mounts on a backplate in horizontal or vertical orientation. Depth is 86 mm, width 105 mm, height 161 mm. Connection pitch is 35 mm. Front connections both upstream and downstream. IP40 enclosure protection; IK07 impact resistance.
