LAL36125 - 125 Amp Circuit Breaker

LAL36125 - 125 Amp Circuit Breaker

The LAL36125 is a 125-amp, 3-pole Type LA molded-case circuit breaker for compatible electrical equipment that requires a unit-mount breaker with line and load lugs. When you're matching an existing breaker, look beyond the 125A rating. The LAL36125 measures about 11 inches high, 6 inches wide, and 5.84 inches deep, and its mounting style, lug arrangement, voltage rating, and interrupting capacity must match the equipment.

Key Features and Benefits

• 125A, 3-pole design: Made for compatible three-pole applications requiring a 125-amp breaker.
• 600VAC rated: Provides a clear voltage rating to match the breaker to existing equipment.
• Thermal-magnetic operation: Combines thermal overload sensing with magnetic short-circuit sensing.
• Push-to-Trip: Allows manual tripping without exposure to live parts.
• Unit-mount configuration: Designed for applications that require this particular mounting arrangement.
• Line and load lugs: Lug connections are provided on both sides of the breaker.

Material Compliance and Certifications

The LAL36125 is UL Listed and carries CSA and IEC certifications.

The supplied product information does not identify specific RoHS, REACH, or other material-compliance declarations, so do not assume them. If a project requires a particular material standard, confirm it using the product markings and applicable equipment documentation.

Where It Works Best

The LAL36125 makes the most sense in compatible existing and legacy electrical equipment that calls for a 125A, 3-pole Type LA unit-mount circuit breaker. Match the breaker by its complete set of specifications, not amperage alone.

Before installation, compare the existing application with the LAL36125 catalog number, Type LA configuration, 125A rating, three poles, 600VAC rating, 22kA interrupting capacity, dimensions, mounting style, and line/load lug arrangement. The available fault current at the installation must also fall within the breaker's applicable interrupting rating.
