At 45 mm wide and 81 mm deep, it leaves 0 mm clearance needed backwards or to the side — you can pack these tight on a rail without derating for air gap. Spring-loaded terminals on both the main current circuit and the auxiliary/control circuit. Main contacts accept 2x (0.25 to 2.5 mm²) solid or 2x (0.25 to 1.5 mm²) finely stranded with ferrule. AWG equivalent is 2x (24 to 14). No screw torque to check — push the wire in, it's clamped. The auxiliary switch slot is available (product extension yes), so you can add a signal contact without re-terminating the power side. Breaking capacity drops with voltage: 100 kA at 240 V and 400 V AC, then 3 kA at 500 V, and 2 kA at 690 V. At 690 V AC-3 max, it's still rated — but the fault current it can interrupt is much lower. For a 400 V panel with high available fault current (say 65 kA), this breaker still has headroom. ## Sourcing posture This is a current-production Siemens part, sourced through independent distribution. If you need to fill a BOM line or replace a failed unit in a live panel, send the order code and quantity — we'll quote the best channel.","metaTitle":"Siemens 3RV1011-1FA20 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV1011-1FA20 SIRIUS motor protection circuit breaker, 5 A continuous, CLASS 10 trip, 100 kA breaking at 400 V AC, spring terminals.

The key difference is the continuous current rating — the 1HA10 is set for a different motor size. Verify the motor FLA on your nameplate before substituting; the frame and terminal style are the same, so it will physically drop into the same DIN rail footprint without rewiring."},{"question":"Will 3RV1011-1FA20 drop into a panel specified around 3RV1011-1HA10 without rewiring?","answer":"Yes, both share the same 45 mm width, 81 mm depth, and spring-loaded terminal layout. The mounting rail and clearance requirements are identical. The swap is mechanical — no terminal rework needed — but the trip current differs, so confirm the motor protection setting matches the load."},{"question":"What compliance documentation does Siemens provide for 3RV1011-1FA20?","answer":"RoHS compliance is confirmed with a substance prohibition date of 01.01.2013. The part carries IP20 finger-safe touch protection and is designed to IEC/EN 60947 standards for motor protection circuit breakers. UL and CSA listings are typical for the SIRIUS series, though the specific file numbers are not in this listing."},{"question":"Where can I buy 3RV1011-1FA20 and what is the lead time?","answer":"Sourced and quoted to order against an RFQ through independent distribution.
