Engineered for residential and commercial power distribution, the CROUSEMPH2110 delivers reliable thermal-magnetic trip functions. This two-pole, 110-amp component provides essential overload and short-circuit mitigation for larger branch circuits or subpanels. It mounts into compatible Murray Type MP, Siemens, and Crouse-Hinds load centers. Electricians frequently utilize this model when servicing older enclosures, and it crosses over to the modern Q2110 replacement.
Which load centers are compatible with the MP2110 circuit breaker?
This plug-in breaker is designed for use in Crouse-Hinds, Murray, and Siemens load centers that accept Type MP or MP-T miniature circuit breakers.
Is the Crouse-Hinds MP2110 the same as the Murray or Siemens MP2110?
Yes. Siemens acquired the residential electrical lines of both Murray and Crouse-Hinds. The MP2110 catalog number represents the exact same 110A, 2-pole breaker across all three brands.
What is the modern replacement for the MP2110 breaker?
The Siemens Q2110 is the direct modern replacement for legacy Type MP and MP-T 110A 2-pole breakers used in older Murray and Crouse-Hinds enclosures.
Is the MP2110 breaker HACR rated?
Yes, this breaker is HACR rated, making it suitable for protecting heating, air conditioning, and refrigeration equipment branch circuits.
What does the LI trip function indicate on this breaker?
The LI designation means it uses a thermal-magnetic trip unit. The thermal component provides a long-time delay to prevent nuisance tripping from temporary overloads, while the magnetic component offers instantaneous tripping during severe short circuits.
Can the MP2110 be installed in systems with an available fault current above 10kA?
No. This breaker has a maximum interrupting rating of 10kAIC at 240V. It must not be used in panels where the available fault current exceeds 10,000 amps.
What wire sizes are accepted by the load lugs on the MP2110?
The load terminals accept 2 AWG to 1/0 AWG copper conductors, or 1/0 AWG to 2/0 AWG aluminum conductors. Always ensure proper torque is applied during installation as specified on the breaker label.
