Selection Trade-offs
-
Current class 0.28–0.4 A vs. adjacent ratings — The EA10 suffix defines the adjustable thermal trip band. Table-range alternates (AA10 at 0.11–0.16 A, BA10 at 0.14–0.2 A, GA10 at 0.45–0.63 A, JA10 at 0.7–1 A) share the same frame and DIN footprint but require matching the motor FLA to the correct band.
-
Screw vs. spring cage termination — The primary MPN uses screw-type line contacts. EA20 substitutes spring cage; EA40 uses ring lug; EA25 adds a 1NO/1NC auxiliary in a side-mount configuration. Mechanical termination style affects panel wiring labor and available tooling.
-
Bulk vs. box packaging — The seed ships bulk-packed. Most alternates list box packaging, which may influence quantity breaks or storage preferences in panel production environments.
-
Approval coverage variance — The seed carries CCC, CSA, EAC, IECEx, and UL. Several alternates (EA15, EA20, EA40, EA25, AA10) add ATEX, CE, and VDE. If hazardous-area motor protection is required, verify the specific alternate approvals against the installation classification.
-
Thermal vs. thermal-magnetic trip characteristic — The seed records "Thermal" breaker type. EA15, EA20, EA40, EA25, and AA10 are classified "Thermal Magnetic." This distinction affects coordination with downstream motor contactors in overload relay cascades.
Integration Notes
The 3RV2011 series occupies the Siemens S00 size class. All listed parts mount to 35 mm DIN rail and provide a rotary manual actuator. The three-pole configuration carries all three motor phases through the thermal element. Auxiliary contact options (as seen in EA25) mount in the accessory slot and do not alter the core thermal-magnetic unit.

Why they are similar
- 3RV20110EA15 matches rated current and screw termination; it adds ATEX/CE/VDE approvals and classifies the breaker as thermal magnetic.
- 3RV20110EA20 matches current and mounting; spring cage replaces screw terminals.
- 3RV20110EA25 shares the same current band and screw connection but includes a 1NO/1NC auxiliary contact block.
- 3RV20110EA40 shares current and mounting but uses ring-lug terminations.
All five share the same DIN-rail S00 frame, three-pole count, and rotary actuator type.
