What is the current rating for Siemens 3RV20111FA20?

The catalog record for 3RV20111FA20 shows a 5 A current rating. The Siemens 3RV2011 S00 series spans lower current bands (1.8 A, 2.5 A, 4 A) in other in-catalog variants, but this specific MPN is listed at 5 A.

Does the 3RV20111FA20 include auxiliary contacts?

No. 3RV20111FA20 is the basic spring-terminal variant without auxiliary contacts. In-catalog alternatives 3RV20111FA25 and 3RV20111FA15 include 1NO+1NC auxiliary contact configurations while sharing the same S00 frame dimensions.

Which approval agencies cover the 3RV20111FA20?

The record lists ATEX, CCC, CSA, EAC, IECEx, and UL. Several comparison variants (3RV20111FA25, 3RV20111FA40) extend coverage to CE and VDE — qualification for a specific installation region requires matching the MPN to the approval package actually on record.

Siemens 3RV20111FA20 Motor Protection Circuit Breaker

MPN Structure and Catalog Context

The prefix 3RV identifies this as a Siemens SIRIUS motor protection circuit breaker. Within the 3RV2011 family (S00 size), the designation breaks down as follows: 3RV20-111-FA20 — "111" denotes three-pole thermal type with rotary handle; "FA20" specifies the 3.5–5 A current range with spring-clamp load-side terminals. The seed record shows a bulk-packaged unit without auxiliary contacts; in-catalog variants add screw-type terminals, ring-lug terminations, and auxiliary contact configurations under the same thermal/frame architecture.

The 3RV2011 series occupies the S00 (45 mm width) frame within Siemens' SIRIUS motor protection portfolio. These devices serve as direct-on-line motor starters and feeder breakers in control cabinet layouts.

Why the Top Similar Variants Match

3RV20111FA25 — Shares identical current rating, 3-pole rotary-actuator DIN Rail architecture. Adds auxiliary contacts (1NO+1NC) and thermal-magnetic construction versus the seed's thermal-only design; expanded approval coverage includes CE and VDE. The box encapsulation reflects a package format difference rather than a functional distinction in the protection mechanism.

3RV20111FA40 — Matches the seed on all primary protection parameters (5 A, 3-pole, rotary, thermal magnetic). Title references ring-lug load-side connection; the shared spec keys do not capture termination type, so direct comparison on that axis is not possible from this record.

3RV20111FA10 — Retains the seed's thermal-only breaker type and bulk encapsulation while dropping any auxiliary contact configuration. Both devices share identical approval agency coverage and physical form factor.

Selection Trade-offs

Spring-clamp (FA20) versus screw-terminal (FA10) load-side connections affect wiring practice and tool requirements — spring-clamp allows tool-free conductor insertion within the rated cross-section range.
Thermal-only (FA20, FA10, FA15) versus thermal-magnetic (FA25, FA40, FA150BA0, FA100BA0) impacts coordination with downstream motor thermal overload relay settings in direct-on-line arrangements.
Bulk packaging suits high-volume panel assembly; box encapsulation may simplify single-unit procurement and storage.
Auxiliary contact availability (FA25, FA15) supports feedback signal paths for status monitoring or interlock logic without additional enclosure footprint.
Global certification breadth (ATEX, CCC, CSA, EAC, IECEx, UL) covers most industrial export markets; the BA0 variants restrict to CE/EAC/VDE, which may limit multinational deployments.

FAQ

What is the current range for 3RV20111FA20?

The catalog record shows a 5 A rating. The product family spans 1.8–5 A across the 3RV2011 series variants, but only the 5 A rating is on record for this specific MPN.

Does 3RV20111FA20 include auxiliary contacts?

No. The seed MPN is a basic unit without auxiliary contacts. Variants such as 3RV20111FA25 and 3RV20111FA15 include 1NO+1NC auxiliary contacts under the same 45 mm S00 frame.

What approval agencies apply to 3RV20111FA20?

ATEX, CCC, CSA, EAC, IECEx, and UL are listed for the seed. Several in-catalog variants add CE and VDE certifications — confirm against the specific MPN required for a given installation region.
