Siemens 3VA2110-6JP36-0AA0

The 3VA21 circuit breaker is designed for low voltage applications, featuring an electronic trip unit (ETU550) with an LCD display and LSI capabilities. This model supports a rated current of 100A across three poles and offers a high breaking capacity of 85kA at 415V, which is essential for effective overload and short-circuit protection. The unit provides adjustable short-circuit release settings ranging from 0.6 to 10 times the rated current (In) and up to 12 times for instantaneous protection (Ii).

Constructed with a focus on reliability, the breaker has a degree of protection rated at IP40, ensuring its durability in various environments. The device measures 4.1 inches in width, 7.1 inches in height, and 4.2 inches in depth, making it suitable for various installations, including DIN rail mounting options.

For enhanced functionality, the circuit breaker includes a connection with a box terminal and a steel wrap-around lug, making it versatile for different applications. Additionally, it provides the option for external current transformer integration to protect the neutral conductor, allowing for configurations that can handle up to 160% of the rated current.
