Design Of The Productfor motor protection

Product details

It provides overload and short-circuit protection for motors up to 0.06 kW at 400 V. The continuous current rating is 0.2 A, and the trip class is CLASS 10, meaning it will trip within 10 seconds at 7.2× the set current — fast enough to protect standard induction motors during a locked-rotor event without nuisance tripping on normal startup. This is a high-interrupting rating for a 45 mm wide device, giving selectivity headroom in a distribution panel.

Width is 45 mm, height 97 mm, depth 96 mm — standard for the SIRIUS 3RV1 frame. Mounting position is any, which helps in tight enclosures. The front face is IP20, so finger-safe when installed in a panel with the door closed. Main circuit terminals are screw-type, accepting solid or stranded conductors: 2x (1 … 2.5 mm²) or 2x (2.5 … 6 mm²). AWG equivalents are 2x (14 … 10). No auxiliary contacts are included (0), but an auxiliary switch can be added externally.

Environmental and electrical ratings

Shock resistance is 25g for 11 ms. The maximum switching frequency at AC-3 duty is 15 operations per hour.

Frequently asked questions

Does this breaker include phase failure detection?

Yes, phase failure detection is built in — it will trip on loss of any phase to protect the motor.

What terminal type does the 3RV1021-0BA10-0FJ0-ZX95 use?

Screw-type terminals on the main circuit, accepting 2x (1 … 2.5 mm²) or 2x (2.5 … 6 mm²) solid or stranded conductors.
