Providing essential whole-panel protection, the MPD2150 functions as a primary disconnect for residential electrical systems. This 150-amp, two-pole component ensures safe power distribution. The plug-on design integrates seamlessly with legacy Murray and current Siemens panelboards. It serves as an exact functional equivalent to the newer QN2150, making it ideal for maintaining existing infrastructure. Featuring a standard 10kAIC rating, it includes reliable thermal-magnetic trip technology.
What load centers are compatible with the MPD2150 circuit breaker?
The MPD2150 is designed for use in both Siemens and legacy Murray load centers and meter combinations. It is commonly used as a main breaker or a high-amperage branch breaker in these panels.
How many panel spaces does the Siemens MPD2150 require?
This 2-pole molded case circuit breaker requires four standard 1-inch panel spaces for installation.
What is the direct replacement for the legacy Murray MPD2150?
The Siemens QN2150 serves as an exact functional drop-in replacement for the legacy MPD2150 breaker. Since Siemens acquired Murray, their components are largely interchangeable for residential load centers.
Can the MPD2150 be used as a back-fed main breaker?
Yes, but when installed as a back-fed main breaker in a branch position, it requires an approved hold-down kit, such as the Siemens ECMBR2, to secure it to the load center base pan in accordance with NEC requirements.
