Leviton LB250 2-pole Branch Circuit Breaker 50A

Product Description

The LEVITON LB250 is a standard 2-pole branch circuit breaker rated at 50 amps and 120/240 volts with a 10KA interrupt rating. It is designed for residential and light commercial load centers where a dedicated double-pole circuit is required. The LB250 provides overcurrent protection by automatically tripping when current exceeds the rated ampacity, isolating the downstream circuit and protecting connected equipment and wiring. Licensed electricians install this breaker as part of panel builds, service upgrades, or circuit additions requiring a 50-amp double-pole position.

The LB250 is suited for 120/240-volt branch circuits typically serving high-draw loads such as electric ranges, dryers, HVAC equipment, or EV charging circuits in residential panels. Its standard form factor fits load centers that accept the LB-series breaker line. The 10KA interrupt rating meets the fault-current requirements of most residential and light commercial service entrances.

Key Features

• 50-amp double-pole configuration for 120/240-volt branch circuits
• 10KA interrupt rating for adequate fault-current protection in residential and light commercial applications
• Standard form factor compatible with LB-series load centers
• Automatic trip mechanism isolates overcurrent faults to protect wiring and connected loads
• Dual-pole design simultaneously disconnects both ungrounded conductors

Compatibility

Designed as an OEM-style replacement or new-installation breaker for load centers accepting the LEVITON LB-series 2-pole breaker format.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NFPA 70 (National Electrical Code) and applicable local codes. De-energize the panel at the utility disconnect or main breaker before handling any bus bar connections. Verify the panel's available fault current does not exceed the 10KA interrupt rating before installing. Never work on an energized load center interior.
