SENTRON 3VA MCCB, Thermal Magnetic Trip Unit - 3VA1116-5EF32-0AA0

Product Description

Siemens SENTRON 3VA MCCB with Thermal Magnetic Trip Unit – 3VA1116-5EF32-0AA0

The Siemens 3VA1116-5EF32-0AA0 is a high-performance Molded Case Circuit Breaker (MCCB) from the SENTRON 3VA1 series, designed to protect low-voltage electrical distribution systems against overload and short-circuit faults. This 3-pole MCCB comes with a Thermal Magnetic Trip Unit (TM240 / ATAM type), offering adjustable overload and adjustable short-circuit protection, making it suitable for more flexible and selective coordination applications in industrial power systems.

It is widely used in LT panels, MCC/PCC systems, feeder circuits, and main distribution boards, where high breaking capacity and adjustable protection settings are required.
