Leviton Mfg Co R10-LB120-0TR 20A 1-pole Circuit Breaker

Product Description

The LEVITON MFG CO R10-LB120-0TR is a 20-amp, 1-pole standard branch circuit breaker rated for 120/240 volts. It uses thermal magnetic trip technology, which provides dual-mode protection: the thermal element responds to sustained overloads and the magnetic element trips instantly on short-circuit faults. The plug-on design allows fast, tool-free installation into compatible load centers. This breaker is installed by licensed electricians during panel work, new construction rough-in, or service upgrades in residential and light commercial applications.

This breaker is suited for residential and light commercial branch circuit protection. Typical applications include general-purpose 20-amp circuits serving outlets, small appliances, and lighting loads. The plug-on bus connection eliminates the need for separate bus lugs, streamlining installation in supported load centers. It is sold in a package of 10 units, making it practical for multi-circuit panel builds or service work requiring multiple breakers of the same rating.

Key Features

• 20-amp, 1-pole configuration for standard branch circuit protection
• Thermal magnetic trip provides both overload and short-circuit fault protection
• Plug-on installation design for fast, secure bus connection
• Rated 120/240 volts for compatibility with standard residential panel voltages
• Packaged in quantities of 10 for efficient stock and multi-circuit jobs

Compatibility

Designed as an OEM-style replacement or new-installation breaker for residential and light commercial load centers accepting plug-on style single-pole breakers rated at 120/240 volts.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NFPA 70 (National Electrical Code) and all applicable local codes. Always de-energize the panel at the utility disconnect and verify absence of voltage with a calibrated meter before handling bus bars or installing breakers. Confirm the load center accepts plug-on style breakers before snapping the breaker onto the bus. Do not exceed the panel's maximum circuit count or the breaker's 20-amp continuous load rating.
