LGB2B020B

The Siemens LGB2B020B is a molded case circuit breaker (MCCB) that belongs to the VL Series. It is engineered for effective load protection with a rated current of 20 A. This circuit breaker is capable of operating at a service voltage of 480 VAC, delivered through a two-pole configuration that ensures reliable connection. Additionally, it can handle an alternate voltage rating of 600Y/347 VAC, which broadens its application across different electrical setups.

Key features include an interrupt rating of 65 kAIC at 480 V, lending substantial fault protection ability, and a 14 kAIC breaking capacity at 600 V. The thermal-magnetic trip mechanism enhances operational safety and robustness, quickly responding to overload and short-circuit conditions. This module is compatible with both 50 Hz and 60 Hz AC power frequencies, thus providing versatility in various environments.

Mounting is limited to panelboard assembly, ensuring a secure installation. The connection is established using load-side lugs or a low tab configuration, allowing for efficient wiring integration. This breaker supports a wire gauge range that accommodates copper wires from 14 to 6 AWG and aluminum wires at sizes 12 to 10 AWG. This makes the LGB2B020B a practical choice for ensuring safe electrical distribution across single-phase circuits while offering internal protection mechanisms against overloads and short circuits.
