KCL34150 - 150 Amp Circuit Breaker

KCL34150 - 150 Amp Circuit Breaker

A KCL34150 isn't something you choose by amperage alone. If you're replacing a breaker in existing equipment, the smaller details can be just as important as the 150A rating. This 3-pole Type KCL molded-case circuit breaker has a thermal-magnetic configuration and includes both line and load lugs. For maintenance work on compatible legacy equipment, the KCL34150 makes sense when its breaker type, ratings, dimensions, pole configuration, and connections align with what's already required. Properly matched to the application, professionally installed, and kept within its stated ratings, the KCL34150 is built to last.

Key Features and Benefits

• 150-amp, 3-pole configuration: Designed for applications that specifically require this amperage and pole arrangement.
• Type KCL construction: An important identifier when you're trying to match an existing breaker rather than simply finding one with the same amp rating.
• Thermal magnetic breaker: Provides the specified trip configuration for equipment calling for this breaker type.
• Line and load lugs are included: both are supplied with the breaker so that this connection detail can be factored into the replacement match.
• 60Hz, 40°C specifications: Two more details that should be checked as part of the overall application match.

Material Compliance and Certifications

No specific material-compliance information or certification listings were included in the available specifications for the KCL34150. Because of that, certifications or standards such as UL, CSA, RoHS, or REACH should not be assumed.

Where It Works Best

The KCL34150 150-amp circuit breaker is intended for compatible electrical equipment that requires its specific Type KCL form, 3-pole configuration, thermal-magnetic design, and electrical ratings. It's especially relevant when maintaining legacy equipment, where correctly matching the existing breaker matters.

A good replacement check goes beyond seeing "150A" on the label. Compare the KCL34150 part number, three-pole arrangement, Type KCL designation, 60Hz specification, and 40°C rating with the existing application. The required interrupting capacity must correspond to the system: 65 kAIC at 480 VAC or 100 kAIC at 240 VAC, as applicable.
