Its interrupting capacity hits 187 kA at 240 V and 121 kA at 415/440 V, dropping to 9 kA at 690 V — so the SCCR headroom at typical 400 V class panels is solid for most downstream fault scenarios. The basic switch variant is 3VA2463-5JQ32-0AA0, and this order code adds communication capability.
Maximum power loss is 162 W at full load.
187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V (–). At typical 400 V class distribution, the 121 kA rating provides generous headroom for high-fault installations.
