New Original Siemens 3ZX1012‑0RV01‑1AA1 3RV1021‑4BA10 Motor Protection Circuit Breaker
Product Overview
The Siemens 3RV1021‑4BA10 (order reference 3ZX1012‑0RV01‑1AA1) is a brand‑new original SIRIUS‑series 3‑pole motor protection circuit breaker (MPCB) in S0 frame size. It integrates thermal overload release and magnetic short‑circuit release for three‑phase asynchronous motor protection. The adjustable thermal setting range is 14‑20 A, suitable for 7.5 kW three‑phase motors under 400 V AC supplyState Elec…. Widely applied in fan, pump, conveyor, machine‑tool and packaging‑machine motor feeder circuits. Marked as “New Original”, it means genuine factory‑manufactured unit with full‑factory function testing, intact bimetallic strips and magnetic trip assemblies, free of refurbished or second‑hand products. It can perform manual motor switching as well as overload and short‑circuit fault interruption in one compact device。
Main Functions
- Dual‑protection thermomagnetic trip: Thermal bimetallic overload protection and instantaneous magnetic short‑circuit protection for three‑phase motors.
- Adjustable overload current dial: Continuous setting from 14 A to 20 A to match motor rated full‑load current.
- Class 10 overload trip characteristic: Standard motor trip class for general‑purpose asynchronous motors.
- Rotary operating handle: ON/OFF manual switching, visible trip indication, padlock‑capable for lock‑out tag‑out maintenance.
- Built‑in test function: Manual test button to verify mechanical tripping performance on site.
- Modular expandable design: Supports external auxiliary contact blocks, fault‑signal contacts and shunt‑trip accessories.
- Two installation options: 35 mm DIN‑rail snap‑on mounting or direct screw panel mounting, any installation orientation allowed.
- High short‑circuit breaking capacity: Quickly cuts short‑circuit faults to protect downstream motor and wiring.
Technical Characteristics
- S0 compact frame size, screw‑type main circuit terminals, finger‑safe IP20 terminal protectionRS.
- Trip class Class 10; magnetic short‑circuit instantaneous trip at approx. 12×max setting current.
- High breaking capacity: 55 kA at 400 V AC, 100 kA at 240 V AC.
- Mechanical service life up to 100 000 switching cycles for frequent‑start motor applicationsState Elec….
- Surge voltage withstand 6 kV, pollution degree 3 for industrial control cabinet environment.
- Complies with IEC 60947‑2, IEC 60947‑4‑1 standards; CE, UL, CSA certified.
- RoHS‑compliant flame‑retardant plastic housing.
- No built‑in auxiliary contacts; auxiliary switches need separate accessory installation.
