Design Of The Productfor motor protection

Product details

The screw-type terminals accept solid conductors up to 2x 1.5 mm² (fine-stranded up to 2x 2.5 mm²) for the main circuit, and up to 2x 6 mm² stranded for auxiliary wiring. Front IP20 protection keeps live parts behind the enclosure face during panel access.

Rated at 0.75 kW at 400 V AC for motor duty, with a maximum operating frequency of 15 cycles per hour at AC-3. Shock resistance is 25g for 11 ms. The auxiliary switch is transverse design and field-installable. Ground fault detection is not built in — external GF protection is required if needed. RoHS compliance date is 01.05.2012 (substance prohibitance date).

Frequently asked questions

Will 3RV1021-1BA15-ZW97 drop into a panel specified around 3RV2021-1FA15 without rewiring?

Both parts share the same SIRIUS family footprint and 45 mm width on 35 mm DIN rail, so mechanical fit is identical. However, the 3RV2021-1FA15 is a different current rating point — verify the continuous current and trip class match your motor FLA before substituting. Terminal wire ranges are similar but not identical; check the specific conductor cross-sections against your existing wiring.
