5SJ4220-7HG41
The 5SJ4220-7HG41 is a Siemens SENTRON 5SJ4 series double-pole miniature circuit breaker with a rated current of 20 amps, C-characteristic tripping (magnetic trip point 5~10 times the rated current), short-circuit breaking capacity of 14kA, 35mm DIN rail mounting, and terminal wiring on the line load side. It is suitable for use in industrial distribution panels and control boxes.
Product Positioning
The 5SJ4220-7HG41 is a double-pole miniature circuit breaker from the Siemens SENTRON 5SJ4 series. It features a C-characteristic tripping mechanism and a 14kA short-circuit breaking capacity, providing stable overload and short-circuit protection for power distribution circuits.
Core Product Advantages and Features
C-characteristics breakout design
The magnetic tripping action range is 5 to 10 times the rated current, with a moderate response speed, making it suitable for short-circuit protection of general lighting, sockets and other load circuits.
Bipolar circuit breaker
At the same time, disconnect the two pole circuits to ensure complete isolation of the line and improve power distribution safety.
14kA short-circuit breaking capacity
It has a rated short-circuit breaking capacity of 14kA and can withstand instantaneous short-circuit current impact and safely disconnect.
Standardized DIN rail installation
It adopts a 35mm standard DIN rail for quick fastening, and both the line side and the load side have terminal wiring, which facilitates the construction and maintenance of the distribution box.
