LGB3B040B

The Siemens LGB3B040B is engineered as a molded case circuit breaker, part of the VL Series, intended to deliver solid electrical protection for diverse applications. With a nominal coil voltage rated at 600 volts AC, this device suits high-voltage installations. The breaker consists of two poles, capable of managing an amperage load of up to 40 amperes, accommodating a variety of wire sizes ranging from 8 AWG to 1/0 AWG.

This breaker operates in a three-phase system, contributing to its versatility in industrial settings. Its G frame type offers a reliable structure, while the thermal magnetic trip unit provides effective monitoring and response to electrical overloaded conditions. The mounting configuration is designed for use with panel board buses, allowing easy installation.

In terms of performance, the circuit breaker is rated to handle an ampere interrupt capacity reaching 100 kiloamperes at 240 volts AC, providing additional safety against electrical faults. It complies with both CSA and UL certification standards, ensuring that it meets rigorous safety requirements. Operating within a frequency range of 50 to 60 hertz makes it adaptable for typical electrical systems.
