Product details

Motor protection circuit breaker for 36 A AC-3 duty

It carries a rated operational current of 36 A at AC-3 400 V and a Trip Class 10 characteristic, meaning it will trip within 10 seconds at 7.2× the set current — standard for protecting standard induction motors during start-up. The breaker is rated for a maximum voltage of 690 V and operates at 50/60 Hz.

The S0 frame occupies 45 mm width, 97 mm height, and 96 mm depth. Clearance requirements: 70 mm upward and downward, 30 mm at the sides, 0 mm forward and backward. Screw-type terminals on the main current circuit accept 2×(1…2.5 mm²) solid/stranded or 2×(2.5…10 mm²) solid, with a tightening torque of 2…2.5 N·m. Connectors arranged top and bottom.

Operating temperature range -20 to +40 °C; transport/storage -50 to +80 °C. Relative humidity during operation 10 to 95 %. Installation altitude up to 2000 m. Shock resistance 25 g / 11 ms per IEC 60068-2-27. RoHS compliance date 05/01/2012. Surge voltage resistance rated at 6 kV.

Frequently asked questions

What are the key ratings of 3RV6021-4PA10?

Rated operational current 36 A at AC-3 400 V, Trip Class 10, maximum voltage 690 V, frequency 50/60 Hz, S0 frame.

What is the closest functional alternative to 3RV6021-4PA10?

The 3RV6021-4DA10 is a peer in the same S0 frame and SIRIUS family, but its exact ratings differ; verify the AC-3 current and trip class against your motor data before substituting.

Will 3RV6021-4PA10 drop into a panel specified for 3RV6021-4DA10 without rewiring?

Both share the S0 frame and screw-type terminals, so the physical footprint and terminal arrangement are the same. Confirm the rating difference — the 4PA10 is 36 A AC-3; the 4DA10 may differ — before committing the BOM line.
