3VJ1105-7EA42-0AA0 | MCCB 50 A, 4 Pole, 55 kA, Fixed O/L & Fixed S/C Settings, Thermal Magnetic Trip Unit (FTFM) – Siemens

The 3VJ1105-7EA42-0AA0 is a high-performance Molded Case Circuit Breaker (MCCB) manufactured by Siemens, designed to provide reliable protection for electrical circuits. This MCCB is rated for a current of 50 A and features a 4-pole configuration, making it suitable for a wide range of industrial and commercial applications.

With a breaking capacity of 55 kA, this circuit breaker ensures robust protection against short-circuit currents, safeguarding your electrical systems from potential damage. The Fixed Overload (O/L) and Fixed Short-Circuit (S/C) settings allow for precise and consistent protection, ensuring optimal performance under varying load conditions.

The Thermal Magnetic Trip Unit (FTFM) integrated into this MCCB provides dual protection. The thermal component protects against overloads by responding to prolonged overcurrents, while the magnetic component offers instantaneous protection against short-circuit currents. This combination ensures comprehensive protection for your electrical installations.

Designed for fixed installations, this MCCB is ideal for applications where the circuit breaker does not need to be frequently removed or replaced. Its durable construction and high-quality materials ensure long-term reliability and performance, even in demanding environments.
