Product details

Motor protection circuit breaker, 4 A, Class 10

The spring-loaded terminals on the main circuit accept 0.25 to 2.5 mm² solid or stranded wire (24 to 14 AWG), which means no screwdriver torque check during commissioning; just strip, insert, and pull to confirm the clamp has bit.

At 690 V the breaking capacity drops to 2 kA, so if the panel is on a 690 V IT system the fault current must be verified against that lower figure.

For a maintenance-spares purchaser holding a legacy cabinet full of SIRIUS 3RV breakers, this unit is a direct drop-in replacement that keeps the spare count current without re-coordination studies.

Depth is 81 mm and height is 90 mm. IP20 on the front face means the live terminals are finger-safe once installed; the panel builder still needs a cover over the rail if the cabinet is open to unskilled access.

Frequently asked questions

What wire sizes does the spring-loaded terminal accept?

The spring-loaded terminals on the main circuit accept 0.25 to 2.5 mm² solid or stranded wire, equivalent to 24 to 14 AWG.

Does 3RV1011-1EA25 include phase failure detection?

Yes, phase failure detection is built in, so the breaker will trip on an unbalanced condition from a single-phased motor.
