3VJ1340-7EA42-0AA0 | MCCB 400 A, 4 Pole, 55 kA, Fixed O/L & Fixed S/C Settings, Thermal Magnetic Trip Unit (FTFM) – Siemens

The 3VJ1340-7EA42-0AA0 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 55 kA, this circuit breaker ensures robust protection against short-circuit currents, safeguarding electrical systems and equipment from damage. It is equipped with a Fixed Overload (O/L) and Fixed Short-Circuit (S/C) settings, providing precise and consistent protection tailored to the specific requirements of the installation.

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

Designed for fixed installation, this MCCB is ideal for applications where the circuit breaker does not need to be frequently removed or replaced. Its compact and durable design ensures long-lasting performance in demanding environments.
