Product details

SIRIUS 3RV1041-4FA10 — Motor-Protective Circuit Breaker, 40 A, CLASS 10

The Siemens 3RV1041-4FA10 is a SIRIUS motor-protective circuit breaker rated for 40 A continuous current with a CLASS 10 trip characteristic, sized for motor loads up to 18.5 kW at 400 V AC.

At 400 V AC the unit interrupts 50 kA; at 240 V AC it handles 100 kA, at 500 V AC 12 kA, and at 690 V AC 6 kA. That 50 kA at 400 V gives solid headroom for most industrial panel SCCR requirements — the breaker clears a fault before upstream devices need to act, which simplifies selectivity studies.

The main circuit terminals accept solid conductors 2x (2.5…16 mm²) and stranded 2x (10…50 mm²) or 1x (10…70 mm²). Auxiliary and control circuits use separate screw terminals. Finger-safe touch protection (IP20 on the front) means it can sit near the panel door without an extra cover.

Protection Functions and Environment

Built-in phase failure detection trips the breaker if one phase drops out — critical for preventing single-phasing damage on a motor. No ground-fault detection onboard, so that function stays with the upstream RCD or drive. Shock rated at 25g / 11 ms. Power dissipation at rated load is 23 W (7.7 W per pole).

Frequently asked questions

Where can I buy 3RV1041-4FA10?

Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.

What is the breaking capacity of 3RV1041-4FA10 at 400 V?

50 kA at 400 V AC, with 100 kA at 240 V, 12 kA at 500 V, and 6 kA at 690 V.

What compliance documentation does 3RV1041-4FA10 have?

The substance prohibition date of 07/01/2006 aligns with RoHS compliance; the part carries IP20 front protection and is designed per IEC/EN standards for motor protection.

Will 3RV1041-4FA10 drop into a panel specified for 3RV6021-4DA10?

Both are 3-pole SIRIUS motor-protective breakers on 35 mm DIN rail, but the 3RV6021-4DA10 is a different frame size with different terminal layouts and breaking capacities — verify terminal positions and panel cutout dimensions before substitution.
