Siemens AG 3vt1704-2ea46-0aa0 Circuit Breaker

Siemens 3VT1704-2EA46-0AA0 is a four-pole molded‑case circuit breaker from Siemens' Sentron 3VT1 protection family, engineered for 415 V AC distribution and rated for 40 A. It delivers a high short‑circuit capacity with an ICU of 25 kA, enabling rapid interruption of faults in multi‑phase circuits found in industrial enclosures and control panels. The device uses a Thermal‑Magnetic (TM) trip system to provide both overload protection and short‑circuit clearance, making it suitable for protecting feeders, motors, and other heavy loads in commercial or industrial settings. As a 3VT1 module, this breaker is designed for compact, robust installation in panelboards and switchgear, offering reliable protection across all four conductors in a 3‑phase system. The -2EA46- designation places this model within the 3VT1704 family that Siemens markets under the LV SENTRON line, aligning with standard documentation and installation practices for Siemens motor protection and distribution components. Typical applications include motor feeders, distribution circuits, and panelboard protection where a high‑reliability, four‑pole device is required to safely interrupt fault currents at 415 V AC.
