Product details

The Siemens 3RV1011-1FA25 is a SIRIUS motor protection circuit breaker rated for 5 A continuous current with a Class 10 trip characteristic, designed to protect three-phase induction motors up to 1.5 kW at 400 V AC. Its breaking capacity reaches 100 kA at 240 V and 400 V AC, dropping to 3 kA at 500 V and 2 kA at 690 V — meaning it can handle high fault currents on low-voltage distribution but needs coordination upstream at higher voltages.

Depth is 81 mm, height 90 mm — the 81 mm depth is worth noting for shallow enclosures where cable bend radius behind the breaker is tight. Spring-loaded terminals on the main circuit accept 2x (0.25... 2.5 mm²) solid or stranded conductors (AWG 24...14), so no screw torque verification needed during commissioning.

Environmental and mechanical margins

Shock rated at 25 g for 11 ms. Main contacts specified for 100,000 mechanical operations.

Frequently asked questions

Will 3RV1011-1FA25 drop into a panel specified around 3RV1011-1HA10 without rewiring?

Both share the same SIRIUS 3RV1 family footprint — 45 mm width, DIN rail mount, same terminal style — so mechanical fit is identical, but verify the trip current and breaking capacity differences between the two order codes before substituting.

What is 3RV1011-1FA25's listed depth?

The depth is 81 mm, which matters for shallow enclosures where cable bend radius behind the breaker is tight.
