Description
Engineered for residential and commercial main service, this 2-pole 150A molded case circuit breaker provides dependable thermal-magnetic protection against overloads and short circuits. Requiring four panel spaces, the plug-on MCCB mounts securely into compatible Murray and Siemens load centers. It serves as an exact replacement for older installations and is fully cross-referenced with the newer QN2150H model. This common-trip breaker is rated for 22kAIC at 120/240VAC and is HACR rated.Specifications

Product FAQs
5 answersHow many panel spaces does the MP2150 require for installation?
This breaker requires four panel spaces across two rows (two spaces on the left and two on the right) to mount securely onto the bus bars.
What is the modern Siemens cross-reference for the Murray MP2150?
The MP2150 crosses over to the Siemens QN2150H. Both models share the same four-space footprint and 22kAIC interrupting rating at 240V.
Can the MP2150 be installed as a branch breaker?
While typically used as a main breaker, it can be installed in a branch circuit position provided the Siemens or Murray load center wiring diagram explicitly lists type MP or QN breakers as acceptable for branch use.
What protection does the LI trip function provide?
The LI designation indicates a thermal-magnetic trip unit with Long-Time and Instantaneous functions. The thermal element provides long-time delay for overload protection, while the magnetic element provides instantaneous tripping for short circuits.
Are the terminal lugs rated for aluminum wire?
Yes, the lugs accept both copper and aluminum conductors from 4 AWG to 300 kcmil. When terminating aluminum wire, ensure the conductors are properly prepped and an approved oxide-inhibiting joint compound is applied.
