MHL36400 - 400 Amp Circuit Breaker

MHL36400 - 400 Amp Circuit Breaker

The MHL36400 is a 400 amp, 3-pole thermal-magnetic molded-case circuit breaker with both line and load lugs included. For your replacement work in existing or legacy electrical equipment, those basic identifiers are only part of the fit check. Together, the amperage, pole count, A.I.C. ratings, physical dimensions, thermal-magnetic design, and lug arrangement make the MHL36400 a straightforward form, fit, and functional replacement candidate when the application calls for these exact specifications. The molded-case construction is built to last when the breaker is correctly selected, installed, and maintained for its intended electrical application.

Key Features and Benefits

• 400 Amp, 3-Pole Configuration: Clearly defined electrical characteristics help simplify comparison with an existing MHL breaker or compatible equipment.
• Thermal-Magnetic Circuit Breaker: The MHL36400 uses the specified thermal-magnetic configuration.
• Line and Load Lugs Included: Both sides include lugs, an important detail when checking the required replacement configuration.
• 60Hz Operation: The specified frequency provides another concrete compatibility point for the electrical system.
• 40°C Rating: Clearly stated in the supplied product specifications for accurate replacement matching.

Material Compliance and Certifications

No specific UL, CSA, IEC, HACR, RoHS, REACH, or other certification or material-compliance information was provided for the MHL36400. These details should not be inferred from the MHL type, molded case construction, or specifications of similar circuit breakers.

Where It Works Best

The MHL36400 400 amp circuit breaker is best evaluated for compatible existing and legacy electrical equipment that requires its specific combination of 400A capacity, three poles, MHL type, thermal magnetic design, 60Hz frequency, 40°C rating, and included line and load lugs.

Check voltage and interrupting capacity together, not independently. The supplied ratings are 25k @ 600VAC, 65k @ 480VAC, and 65k @ 240VAC. Physical fit matters as well, so the stated 9.00"W x 14.00"L x 4.53"D dimensions should be compared with the breaker being replaced and the equipment in which it will be installed.
