The 3VA2040-6JP46-0AA0: The 242 kA interrupting rating at 240 V and 187 kA at 415 V provide substantial fault-current headroom for main or feeder positions in high-capacity distribution. At 500 V the rating drops to 121 kA, and at 690 V it is 3 kA — the latter limits application to low-fault systems or downstream positions at that voltage.
Thermal performance and trip unit
The 40 A continuous rating holds across the full ambient range from 40 °C to 70 °C, meaning no derating is needed in a warm enclosure.
Physical integration
At 181 mm high, 140 mm wide, and 86 mm deep, this 4-pole MCCB fits standard SENTRON mounting patterns.
