At 690 V the SCCR drops to 4 kA — still adequate for most 690 V motor circuits, but verify coordination if the available fault current exceeds that. Rated voltage range is 20 to 690 V, covering low-voltage control circuits up to 690 V line. The breaker detects phase failure but does not include ground-fault detection — that would need an add-on module or a separate ground-fault relay. No forward or backward clearance needed.
Integration — DIN Rail, Screw Terminals, Clearances
The screw-type terminals accept 2x 0.75 to 2.5 mm² solid or stranded, or 2x 4 mm². Main contact screws are M3. Mounting position is any, so horizontal or vertical panel layouts work. The 97 mm height and 45 mm width leave room for adjacent breakers or contactors in a motor starter combination.
Delta — vs. 3RV2021-1GA15 (Higher-Rated Sibling)
The 3RV2021-1GA15 is a larger frame with higher continuous current rating. The 3RV2011-1GA10-ZW97 is the 45 mm compact frame.
