MHL36900 - 900 Amp Circuit Breaker

MHL36900 - 900 Amp Circuit Breaker

The MHL36900 is a 900 amp, 3-pole thermal magnetic molded case circuit breaker for electrical equipment requiring the specific ratings and physical configuration of the MHL type. When you're sourcing a breaker for existing or legacy equipment, amperage alone doesn't tell the whole story. Pole count, interrupting rating, voltage, dimensions, frequency, temperature rating, and lug configuration must all match the application. For legacy replacement work, the MHL36900 can be considered a form, fit, and functional replacement candidate when its complete electrical and physical specifications match the application.

Key Features and Benefits

• 900 Amp Rating: Provides the specified 900A current rating for applications requiring this exact breaker capacity.
• 3-Pole Configuration: The three-pole arrangement is important for compatibility when matching existing electrical equipment.
• Thermal-Magnetic Design: Uses the supplied thermal-magnetic circuit breaker configuration.
• Line and Load Lugs Included: Both line-side and load-side lugs are included, an important detail when comparing a replacement breaker with the existing installation.
• 60Hz Operation: Specified for 60Hz electrical applications.
• 40°C Rated: The supplied 40°C rating provides another key specification to confirm during replacement selection.

Material Compliance and Certifications

No specific UL, CSA, IEC, HACR, RoHS, REACH, or other certification or material-compliance information was provided for the MHL36900. Do not assume these designations based on the breaker type or electrical ratings. If a particular approval, certification, or material-compliance requirement applies to the installation, verify it against authoritative product documentation before use.

Where It Works Best

The MHL36900 900 amp circuit breaker is best for compatible existing or legacy electrical equipment that calls for an MHL-type, 900A, 3-pole thermal-magnetic molded-case circuit breaker with the stated voltage and interrupting ratings. Its included line and load lugs and 9.00" W x 14.00"L x 4.53"D dimensions are especially important when checking form and fit.
