LAL36175 - 175 Amp Circuit Breaker

LAL36175 - 175 Amp Circuit Breaker

The LAL36175 is a 175-amp, 3-pole Type LA molded-case circuit breaker for electrical equipment that requires this combination of ratings, mounting, connections, and physical size. It uses thermal-magnetic protection that responds to both overload and short-circuit conditions. The breaker is rated 22kA at 600VAC and 10kA at 250VDC and comes in a unit-mount configuration with line and load lugs. It also includes a Push-to-Trip feature that lets you manually trip the breaker without exposure to live parts. If you're replacing an existing LA breaker, don't rely on amperage alone.

Key Features and Benefits

• 175A, 3-pole configuration: Matches equipment designed around a 175-amp, three-pole LA breaker.
• Thermal-magnetic trip technology: Uses thermal sensing for overload conditions and magnetic sensing for short circuits.
• Unit mount: Designed for installations requiring this mounting arrangement.
• Line and load lugs: Includes lug connections on both sides of the breaker.
• Push-to-Trip: Allows manual tripping without exposure to live parts.

Material Compliance and Certifications

The supplied specifications identify the LAL36175 as UL Listed, CSA certified, and IEC certified.

The supplier did not provide specific RoHS, REACH, or other material-compliance information, so do not assume those certifications. If a project has specific compliance requirements, check the markings on the breaker and the documentation for the equipment where it will be installed.

Where It Works Best

The LAL36175 is especially relevant when maintaining or repairing existing electrical equipment designed for a 175A, 3-pole Type LA breaker. It's a straightforward replacement candidate when the original installation calls for the same unit-mount design, electrical ratings, lug arrangement, and physical footprint.
