Its breaking capacity reaches 330 kA at 240 V AC and 242 kA at 415 V AC, dropping to 3.7 kA at 690 V AC — the voltage-dependent curve means you size the interrupting rating against the actual fault level at the installation point, not the highest number on the label. Power loss is 0.6 W maximum, negligible for panel thermal budget.
Depth of 86 mm is the body only; allow additional clearance for lug landing and arc-chamber venting per UL 489 / IEC 60947-2 installation rules.
This part is sourced through independent distribution and quoted to order against an RFQ. Availability and current pricing are confirmed at quote time.
Breaking capacity is 330 kA at 240 V AC, 242 kA at 415 V and 440 V AC, 187 kA at 500 V AC, and 3.7 kA at 690 V AC. The interrupting rating is voltage-dependent; size against the actual fault level at the installation point.
No — the 25 A rating holds flat from -25 °C to 70 °C ambient, so no derating calculation is needed for warm enclosures within that range.
