Design Of The Productfor motor protection

Product details

It carries a 0.32 A rated continuous current and a CLASS 10 trip characteristic. The unit includes phase failure detection.

Breaking capacity and panel fit

That 100 kA rating holds at 240 V, 400 V, 500 V, and 690 V, so it is consistent across common industrial supply voltages.

The main circuit accepts solid conductors from 2× (0.5... 1.5 mm²) or 2× (0.75... 2.5 mm²) and stranded from 2× (1... 2.5 mm²) or 2× (2.5... 6 mm²). AWG equivalents for the main contacts are 2× (14... 10). The auxiliary switch is a transverse design and is field-installable — the product extension for an auxiliary switch is supported. No ground-fault detection built in, so if that is needed, plan for an external module.

Frequently asked questions

Will 3RV1021-0DA15-ZW98 drop into a panel designed for 3RV1011-0GA10?

Both are 45 mm wide SIRIUS motor protection breakers with similar DIN-rail mounting, but the 3RV1011-0GA10 is a different frame size and current range. The 3RV1021-0DA15-ZW98 has a 0.32 A continuous rating versus the 3RV1011-0GA10's rating; verify the motor full-load current and the available panel depth (96 mm for this unit) before substituting without rewiring.
