Leviton LB240-G 40A 2-Pole GFCI Hydraulic Magnetic Branch Circuit Breaker

Protect critical systems and people with the Leviton LB240-G 40A 2-pole GFCI hydraulic magnetic branch circuit breaker. Designed for commercial and industrial use, this Leviton circuit breaker delivers reliable ground-fault protection for security, surveillance, monitoring and IT power distribution. The LB240-G supports both 120/208V and 120/240V applications and offers a robust hydraulic magnetic trip mechanism that maintains accurate 40A performance across a wide temperature range—helping ensure predictable operation in equipment rooms, camera enclosures, and remote monitoring sites.

Installation is faster and cleaner with plug-on mounting and a rough-in friendly design that lets electricians wire the load center before breakers are installed. Built-in LEDs clearly indicate trip condition and fault type, while Leviton’s patented reset lockout prevents unsafe resets if GFCI protection is compromised. These features reduce service calls and speed diagnostics for integrators managing security and networked surveillance deployments.

Specify the LB240-G for branch circuit protection where reliable fault detection, ease of install and clear diagnostics matter. Contact your distributor or add to cart to protect your next security or monitoring project.
