Product details

Motor Protection Circuit Breaker, Class 10 — SIRIUS 3RV2023-1KA10

The Siemens 3RV2023-1KA10 is a SIRIUS motor protection circuit breaker in the S0 frame size, designed for motor protection with a Class 10 trip characteristic — meaning it will trip within 10 seconds at 7.2× the thermal setting, which is the standard for protecting standard induction motors during start-up without nuisance tripping on normal inrush. Rated at 12.5 A for AC-3 duty at both 480 V and 600 V, with a breaking capacity of 4 kA at 690 V and 6 kA at AC 690 V, this breaker is sized for motor branch circuits in industrial control panels.

The 45 mm width (S0 frame) fits standard DIN-rail spacing, and the 97 mm depth leaves clearance for wiring behind the panel door. Terminals accept 2× (1 to 2.5 mm²) or 2× (2.5 to 10 mm²) solid or stranded wire, with M4 screws for the main contacts. A Pozidriv size 2 screwdriver tip is specified, with shaft diameter 5 to 6 mm.

Frequently asked questions

What clearance is needed around the 3RV2023-1KA10 in a panel?

Allow 50 mm above and below, 30 mm to the sides, and zero forward or backward clearance. The breaker can be mounted in any position.

Where can I buy the 3RV2023-1KA10?
