MBK175 - 175Amp Circuit Breaker Description
MBK175 - 175Amp Circuit Breaker
When you replace a main breaker, the key question is whether the specifications match the equipment already in place. The MBK175 is a 175-amp, 4-pole main circuit breaker rated at 120/240 volts, and the manufacturer identifies it as a 22K EQ9684 Main. To complete the replacement, use these details as a practical checklist: compare the MBK175's catalog number, amperage, number of poles, voltage, 22K rating, and EQ9684 designation with the existing breaker and the equipment requirements.
Key Features and Benefits
- The 175A rating is specified for equipment that requires this current rating.
- Match the four-pole configuration when replacing an existing breaker.
- Rated 120/240V: This rating is for use in applications that require the stated 120/240V rating.
- The EQ9684 Main designation helps you identify the correct breaker when comparing current equipment and documentation.
- Instead of relying on appearance, you can compare the catalog number and electrical ratings directly.
