MA36450 - 450 Amp Circuit Breaker

MA36450 - 450 Amp Circuit Breaker

The MA36450 is a 450 amp, 3-pole MA thermal-magnetic molded case circuit breaker for compatible I-Line panelboards. When your amperage, pole count, interrupting rating, dimensions, and panelboard requirements align, the MA36450 can be considered a form, fit, and functional replacement candidate.

Key Features and Benefits

• 450 Amp Rating: Suitable for applications specifically requiring a 450A breaker.
• Three Poles: Provides the specified 3-pole configuration for compatible electrical equipment.
• MA Type: Makes it easier to identify and match the required breaker type during replacement work.
• Thermal-Magnetic Circuit Breaker: Uses the specified thermal-magnetic protection configuration.
• Made for I-Line Panelboards: Intended for use with compatible I-Line panelboard equipment.
• 60Hz Operation: Matches electrical systems requiring a 60Hz breaker.
• 40°C Rating: Gives installers a defined temperature rating to compare with application requirements.

Where It Works Best

The MA36450 450A circuit breaker is best suited to existing and legacy electrical equipment where the application specifically calls for a 3-pole, 450 amp MA thermal-magnetic molded-case circuit breaker for an I-Line panelboard. Rather than treating the part number alone as proof of compatibility, compare the actual application requirements with the breaker's electrical and physical specifications.
