MHL36450 - 450 Amp Circuit Breaker

MHL36450 - 450 Amp Circuit Breaker

The MHL36450 is a 450 amp, 3-pole thermal-magnetic molded case circuit breaker with line and load lugs included. For replacement work in your existing or legacy electrical equipment, the details determine whether a breaker belongs in the application. Rather than relying on amperage alone, compare the part number, breaker type, pole count, voltage-specific interrupting rating, frequency, lug configuration, and dimensions with the equipment requirements. When these specifications match, the MHL36450 450 amp circuit breaker can be evaluated as a form, fit, and functional replacement candidate. Its solid molded-case construction is built to last when correctly selected, installed, and maintained for its intended electrical application.

Key Features and Benefits

• 450 Amp Rating: Provides the specified 450A rating for electrical equipment requiring this exact breaker capacity.
• 3-Pole Configuration: The three-pole design is a key compatibility detail when matching an existing MHL breaker.
• Thermal-Magnetic Design: Uses the specified thermal-magnetic circuit breaker configuration within a molded case.
• Line and Load Lugs Included: Both lug positions are specifically included, removing guesswork about the supplied lug configuration.
• 60Hz, 40°C Rating: These published operating specifications provide additional checkpoints when confirming suitability.

Where It Works Best

The MHL36450 is a practical replacement candidate for compatible existing or legacy electrical equipment that specifically calls for a 450A, 3-pole MHL thermal magnetic molded case circuit breaker with line and load lugs.

A proper match should meet the full specification—not just the 450A rating. Confirm the required 25k @ 600VAC, 65k @ 480VAC, or 65k @ 240VAC interrupting rating at the applicable system voltage, along with the 60Hz frequency, 40°C rating, three-pole configuration, included line and load lugs, and 9.00" W x 14.00"L x 4.53"D physical size.
