3VJ1340-3EA42-0AA0 | MCCB 400 A, 4 Pole, 25 kA, Fixed O/L & Fixed S/C Settings, Thermal Magnetic Trip Unit (FTFM) – Siemens

The 3VJ1340-3EA42-0AA0 is a high-performance Molded Case Circuit Breaker (MCCB) manufactured by Siemens, designed for reliable and efficient electrical protection in industrial and commercial applications. This MCCB is rated for a current of 400 A and features a 4-pole configuration, making it suitable for three-phase systems with neutral protection.

With a breaking capacity of 25 kA, this circuit breaker ensures robust protection against short-circuit currents, safeguarding electrical systems and equipment from damage. The Fixed Overload (O/L) and Fixed Short-Circuit (S/C) settings provide precise and consistent tripping characteristics, ensuring optimal performance under varying load conditions.

The Thermal Magnetic Trip Unit (FTFM) combines both thermal and magnetic protection mechanisms. The thermal element protects against overloads by responding to prolonged overcurrents, while the magnetic element provides instantaneous protection against short-circuit faults. This dual functionality ensures comprehensive protection for your electrical system.

Designed for fixed mounting, this MCCB is ideal for applications where space and installation flexibility are not primary concerns. Its durable construction and high-quality materials ensure long-term reliability and performance, even in demanding environments.
