KL3400 - 400Amp Circuit Breaker

KL3400 - 400Amp Circuit Breaker

The KL3400 is a 400-amp, 3-pole Type KL molded-case circuit breaker with an L-Frame, thermal-magnetic configuration, and a 600VAC rating. If you're sourcing one for equipment that's already in service, the physical size deserves just as much attention as the electrical information. Put the part number, Type KL designation, L-Frame, three-pole arrangement, 600VAC rating, and dimensions side by side with the existing breaker and equipment documentation. When those characteristics align with the installation's requirements, the KL3400 may provide the necessary form, fit, and function. Properly selected, installed, and operated within its specified ratings, it's built to last in the equipment it was designed to serve.

Material Compliance and Certifications

Specific material-compliance information and certifications weren't included in the supplied specifications for the KL3400, so no particular listing or compliance standard should be assumed.

Where It Works Best

The KL3400 is best considered when maintaining existing or legacy electrical equipment that requires a 400A, 3-pole Type KL L-Frame molded-case circuit breaker rated for 600VAC. For this kind of replacement work, it's worth looking at the whole breaker rather than stopping once you've found the correct amperage.

Start with the KL3400 part number, 400A rating, three poles, Type KL designation, L-Frame, and 600VAC rating. Then look at the footprint. At 8.25 inches wide, 18.00 inches long, and 5.50 inches deep, the breaker must meet the physical requirements of the existing equipment.
