Siemens LGB3B035B Circuit Breaker – VL Series – 35A – 3 Pole – 600VAC – Thermal Magnetic – Bolt-On – Panelboard Mount

The Siemens LGB3B035B is a VL Series molded case circuit breaker designed for reliable overload and short-circuit protection in commercial, institutional, and industrial electrical distribution systems. Rated at 35A and 600VAC, this 3-pole breaker is intended for three-phase applications requiring compact size, high interrupting capacity, and dependable circuit protection.

Equipped with a thermal-magnetic trip unit featuring Long-Time and Instantaneous (LI) protection functions, the LGB3B035B delivers effective protection against sustained overload conditions and high fault currents. Built on the Siemens LGB (G-frame) platform, it is designed for panelboard mounting and high-performance distribution applications.

This model includes load-side lugs only (TC1GG20) and supports copper/aluminum conductors within the specified wire range, ensuring secure and flexible installation. Its UL listing and high interrupting ratings make it suitable for demanding electrical environments where space efficiency and strong fault protection are required.
