The shunt trip (STL) auxiliary release is included as standard, part number 3VA9688-0BL32 for the integrated trip unit.
This MCCB delivers 75.6 kA at 240 V AC, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V. The 75.6 kA figure at 240 V is the highest short-circuit rating in the 3VA1 line for a 63 A frame — useful for high-fault panels fed by large transformers.
Above that it derates linearly: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C.
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
52.5 kA at 415 V AC. At 240 V it is 75.6 kA, at 440 V it is 32 kA, and at 690 V it is 10.5 kA.
TM240 indicates a thermal-magnetic overcurrent release with a 240 A frame rating. The breaker's continuous rating is 63 A, set by the installed trip unit.
