NGB3B030B | Siemens 3 Pole Circuit Breaker

The Siemens NGB3B030B is a 3-pole circuit breaker from the VL Series, designed for industrial applications requiring robust electrical protection. This circuit breaker features a voltage rating of 600V and is capable of handling currents up to 30A. It is equipped with a standard interrupting capacity of 25kA at 480V, suitable for managing electrical overloads and short circuits in industrial settings. 

Designed for panelboard mounting, the NGB3B030B is particularly suited for applications where reverse feed configurations are necessary. Its bolt-on connection type ensures secure installation and reliable performance. The circuit breaker includes Long-Time and Instantaneous trip functions (LI), enhancing its ability to respond to varying fault conditions effectively. 

Constructed with thermal magnetic technology, the NGB3B030B offers a dual-mode protection mechanism. Thermal protection responds to overcurrents by heating a bimetallic strip, while magnetic protection detects short circuits through electromagnetic induction. This combination ensures reliable operation across a wide range of electrical fault scenarios. 

The molded case design of the NGB3B030B enhances durability and safety, providing robust insulation and protection for internal components. It incorporates load side lug terminals, facilitating straightforward connection to electrical circuits and contributing to ease of installation and maintenance.
