That means you can pack it into a warm cabinet or a sunny panel without losing headroom on the main feeder. Interrupting capacity is 187 kA at 240 V, dropping to 121 kA at 415 V and 9 kA at 690 V. At 690 V the 9 kA rating is lower than some, so check your system's prospective fault level if you're running 690 V. That gives you remote tripping capability and status feedback without adding external relays. The basic switch core is order code 3VA2440-5HL32-0AA0.
