Product details

Motor protection circuit breaker, 0.63 A, CLASS 10

Breaking capacity is 100 kA across the full AC voltage range from 240 V to 690 V, so it can be applied on high-fault-current panels without requiring an upstream current-limiting fuse for most installations. The unit mounts via screw or snap-on onto a 35 mm DIN rail per EN 50022, occupies 45 mm width, and accepts screw-type terminals for the main circuit — solid or stranded conductors from 1 to 6 mm².

Integration and deployment

Designed for motor protection in control panels, the 3RV1021-0GA10-ZW98 includes phase failure detection and is rated for any mounting position, with an IP20 front face — suitable for enclosed panel installation where personnel contact is limited to the front. Shock resistance is 25 g for 11 ms, and surge voltage withstand is 6 kV. The breaker is rated for a maximum altitude of 2000 m and has a mechanical life of 100,000 operations.

Frequently asked questions

What is 3RV1021-0GA10-ZW98's listed depth?

The listed depth is 96 mm.

What conductor sizes does the 3RV1021-0GA10-ZW98 accept?

The screw-type terminals accept solid or stranded conductors: 2x (1 to 2.5 mm²) and 2x (2.5 to 6 mm²).
