Product details

Motor protection circuit breaker, 25 A, Class 10

The thermal-magnetic overload release is Class 10. Size S0 frame, three-pole, with screw-type terminals accepting 2×(1–2.5 mm²) solid/stranded or 2×(2.5–10 mm²) for the main circuit.

Duty cycle and thermal behaviour

Rated for 15 operations per hour at AC-3 duty. Total power loss is 8 W typical. Shock resistance tested at 25 g / 11 ms per IEC 60068-2-27, and surge voltage withstand is 6 kV — both figures confirm the breaker holds its settings and doesn't nuisance-trip under mechanical or electrical transients common in industrial refrigeration compressor starts.

Frequently asked questions

What are the key ratings for the 3RV6021-4DA10?

Rated operational current 25 A in AC-3 duty, 690 V maximum, Class 10 thermal trip, size S0 frame, 45 mm wide, 96 mm deep.

Will the 3RV6021-4DA10 drop into a panel designed for a 3RV1011-1HA10?

Both are size S0 motor protection breakers on 35 mm DIN rail, so the footprint and mounting are compatible. However, the 3RV6021-4DA10 is rated 25 A while the 3RV1011-1HA10 covers a different current range — verify the motor full-load current and trip class match before substituting.
