K3150 - 150Amp Circuit Breaker

K3150 - 150Amp Circuit Breaker

Working with older electrical equipment usually means one thing: the replacement has to match what is already there. That's where the details of the K3150 circuit breaker come in handy. This molded-case breaker is rated at 150 amps, has three poles, and carries the Type K/K-Frame designation. The K3150 is built to last, but choosing the right replacement for your breaker still comes down to form, fit, and function. Check the frame, amperage, pole count, trip design, dimensions, and electrical requirements against the breaker being replaced before installation.

Key Features and Benefits

• 150A, three-pole configuration gives you two of the most important details to confirm when sourcing a replacement.
• Type K / K-Frame design helps narrow compatibility with existing electrical equipment.
• Thermal-magnetic trip design is appropriate for installations that specifically call for this trip configuration.
• Molded-case circuit breaker construction provides a clear product-type reference for identifying the correct part.
• A practical choice when the goal is to maintain the original form, fit, and function of the electrical installation.

Material Compliance and Certifications

Specific certifications and material-compliance information were not included in the supplied K3150 specifications. UL, CSA, IEC, RoHS, REACH, or other certifications should not be assumed. If your installation requires a particular approval or compliance standard, confirm that requirement against the applicable product documentation.

Where It Works Best

The K3150 is best considered for compatible existing and legacy electrical equipment that specifically calls for a 150A, three-pole, Type K/K-Frame molded-case circuit breaker with a thermal-magnetic trip design. Its published dimensions also give maintenance teams and buyers something concrete to compare with the breaker currently installed.

When replacing an existing unit, check more than just the K3150 part number. Confirm the 150A rating, three poles, K-Frame designation, thermal-magnetic trip design, 600VAC specification, and physical dimensions against the original breaker and the requirements of the equipment. That keeps the focus where it belongs: finding the correct form, fit, and functional replacement.
