Product Description

3VJ MCCB, Thermal Magnetic Trip Unit – 3VJ1340-3EA42-0AA0

The Siemens 3VJ1340-3EA42-0AA0 is a robust Molded Case Circuit Breaker (MCCB) from the 3VJ1 series, designed for reliable protection of low-voltage electrical distribution systems in industrial and commercial installations. It uses a Thermal Magnetic Trip Unit (FTFM) that ensures dependable protection against overload and short-circuit faults, maintaining system safety and continuity.

This model belongs to the 3VJ13 frame size (400 A class) with a 3-pole configuration, making it suitable for three-phase electrical networks. It is commonly used in PCC panels, MCC panels, industrial switchboards, OEM equipment, HVAC systems, and infrastructure power distribution systems, where stable and high-capacity protection is required.

The breaker provides a high breaking capacity of 36 kA at 415 V AC, making it suitable for medium-to-heavy industrial fault levels and ensuring secure interruption under short-circuit conditions.
