LX36125G - 125 Amp Circuit Breaker

LX36125G - 125 Amp Circuit Breaker

The LX36125G is a 125-amp, three-pole LX molded-case circuit breaker that has a plug-in configuration, a current-limiting design, and MicroLogic™ thermal-magnetic protection. If you are maintaining an older electrical system that requires an LX breaker with the same electrical and physical specifications, the LX36125G may be a form-, fit-, and function-replacement.

Key Features and Benefits

• The 125 Amp Rating refers to the breaker's 125 Amp Rating for use with electrical equipment that requires this breaker amperage.
• The three-pole configuration provides the required three-pole setup for compatible electrical equipment.
• Plug-in design: The specifications label the LX36125G as a plug-in circuit breaker, which is important when matching it to an existing installation.
• It is classified as a molded case circuit breaker with current-limiting properties.
• The MicroLogic™ Thermal-Magnetic Protection incorporates the stated MicroLogic™ thermal-magnetic configuration.
• It has an adjustable instantaneous pickup feature.
• The ground-fault functions are adjustable, with adjustable ground-fault pickup and delay.

Material Compliance and Certifications

No specific material compliance or certification information was included in the supplied specifications for the LX36125G. For applications that require a particular listing, certification, material standard, or regulatory compliance, its ratings and compatibility must match the specific application rather than being inferred from the part number or product family. Match compatibility to the intended application rather than inferring it from the part number or product family alone.

Where It Works Best

The LX36125G 125A 3-pole circuit breaker is best suited for electrical equipment that explicitly requires an LX plug-in, current-limiting molded case circuit breaker with the same ratings and protective features. It is especially appropriate for maintaining existing or obsolete electrical systems where you must keep the required form, fit, and function.

When assessing whether a replacement is suitable, you should not look at the amperage alone; you must verify that the LX type, with a 125A rating, three-pole setup, plug-in arrangement, the voltage-specific A.I.C. ratings, the MicroLogic™ thermal-magnetic configuration, the adjustable protection features, the ground-fault functions, and the physical dimensions match the requirements of the existing breaker and the equipment. Qualified electrical personnel should confirm suitability for final use.
