It's built around the 3VA platform — the current-production generation that replaced the 3VL series — so it's what you'd spec into a new BOM or a panel upgrade today. Breaking capacity is the headline here: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. The 250 A rating holds flat from 40 °C through 50 °C ambient, then derates to 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. If your panel sits in a hot environment — near a furnace line or in a non-conditioned electrical room in a Middle East or Southeast Asia plant — that derating curve is what governs the real ampacity, not the nameplate 250 A.
Panel fit and auxiliary content
Dimensions are 181 mm high, 140 mm wide, 86 mm deep — a standard 4-pole MCCB footprint for the 250 A frame class. The two HQ aux switches provide independent NO/NC status contacts for remote monitoring or PLC inputs. Maximum power loss is 50.5 W at rated current.
