Breaking capacity is voltage-dependent: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V. At 415 V — the common European three-phase distribution voltage — the 52.5 kA figure gives substantial fault-current headroom for most industrial service-entrance and sub-distribution applications.
Thermal derating and real-world loading
Above that it derates: 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C.
Auxiliaries and integrated trip options
This MCCB ships with two HQ auxiliary switches (form C) for status feedback — open/closed indication to a PLC or remote annunciator. The integrated auxiliary trip is order code 3VA9688-0BL32.
Dimensions: 76.2 mm wide (roughly 3 inches — three 1-inch pole spaces), 130 mm tall, 70 mm deep.
