Product FAQs
5 answersWhich load centers are compatible with the Siemens MBK200?
The MBK200 is designed specifically for use as a main breaker in Siemens EQIII load centers. It is also compatible with older Siemens and Murray EQ type load centers manufactured prior to 2002.
What legacy Siemens main breaker does the MBK200 replace?
The MBK200 serves as a direct replacement for the obsolete Siemens EQ9685 main breaker. It fits into the same legacy EQ series panels.
Can the MBK200 be used to convert a main lug panel?
Yes, this breaker can be installed in a compatible EQIII main lug load center to convert it into a main breaker panel, establishing a primary service disconnect.
What applications are suitable for the 120/240V rating on this breaker?
The 120/240VAC rating makes the MBK200 appropriate for standard single-phase, three-wire residential and light commercial electrical services.
Why must the MBK200 only be used in EQ or EQIII series panels?
Circuit breakers are tested and listed for specific busbar configurations. Using the MBK200 in an unapproved panel can cause improper seating, which increases the risk of arcing, overheating, and electrical fires.
