MBK225 - 225Amp Circuit Breaker

MBK225 - 225Amp Circuit Breaker

When you replace a main breaker in existing electrical equipment, the part number matters—but the ratings have to match, too. The MBK225 is a 225 amp, 4-pole main circuit breaker rated for 120/240V and identified in the manufacturer product description as a 22K EQ9686 Main. For legacy equipment that calls for this specific configuration, the MBK225 can be considered a form, fit, and functional replacement candidate once you confirm the electrical ratings, physical fit, connections, and equipment requirements. Its solid construction is built to last when selected, installed, and maintained correctly.

Key Features and Benefits

• 225 Amp Rating: Rated at 225A for electrical equipment requiring this specific amperage.
• 4-Pole Configuration: The four-pole design is a key specification to confirm when matching an existing main breaker.
• 120/240V Rating: Clearly identified for 120/240V applications.
• EQ9686 Main Identification: Helps distinguish the MBK225 from similar main breaker configurations.
• Built to Last: Solid construction suited to its intended electrical application when correctly selected, installed, and maintained.
