MHL364001386 - 400 Amp Circuit Breaker

MHL364001386 - 400 Amp Circuit Breaker

A replacement circuit breaker has to match more than the amperage on the label. With the MHL364001386, you have a clearly defined 400 amp, 3-pole MHL thermal magnetic molded case circuit breaker with line and load lugs included. For legacy equipment, the practical approach is simple: confirm the MHL type, 400A rating, three-pole configuration, electrical ratings, lug arrangement, and physical dimensions before determining suitability. When those requirements align, the MHL364001386 can be considered a form, fit, and functional replacement candidate for compatible electrical equipment. Its solid molded-case construction is built to last when properly selected, installed, and maintained for its intended application.

Key Features and Benefits

• 400 Amp, 3-Pole Configuration: Clearly defined electrical characteristics make it easier to compare this breaker with existing equipment requirements.
• Thermal-Magnetic Circuit Breaker: The MHL364001386 uses the specified thermal-magnetic design in a molded-case construction.
• Line and Load Lugs Included: This breaker includes both line-side and load-side lugs, an important detail when confirming replacement compatibility.
• 60Hz Operation: The stated 60Hz frequency provides another clear specification to compare with the existing electrical system.
• 40°C Rated: Carries the specified 40°C rating for applications requiring this particular breaker configuration.

Material Compliance and Certifications

The supplied specifications for the MHL364001386 did not include any specific UL, CSA, IEC, HACR, RoHS, REACH, or other certification or material-compliance information. These details should not be assumed from the MHL designation or from specifications associated with similar circuit breakers.

Where It Works Best

The MHL364001386 400 amp circuit breaker is best evaluated for compatible existing or legacy electrical equipment calling for an MHL, 400A, 3-pole thermal magnetic molded case circuit breaker with the same electrical and physical characteristics.

For a form, fit, and functional replacement, confirm the required interrupting rating at the actual system voltage: 25k at 600VAC, 65k at 480VAC, or 65k at 240VAC. The 60Hz frequency, 40°C rating, included line and load lugs, and 9.00" W x 14.00"L x 4.53"D dimensions should also match the application requirements.
