Product Description

The SIEMENS mpp2150 is a Type MPP main circuit breaker rated for 150 amps at 120/240 volts across 4 poles. It is designed for use as a main disconnect or feeder breaker in residential load centers, providing overcurrent protection for the electrical distribution panel. Licensed electricians install this breaker during new construction, panel replacements, or service upgrades. The 4-pole configuration and 150-amp rating make it well suited for whole-panel protection in single-family residential applications. The 10 kA interrupt rating meets standard residential fault-current levels.

This breaker is used in residential electrical distribution systems as a main disconnect for load center installations. It fits into Type QPP/MPP-compatible load centers and serves as a protective device between the utility service entrance and branch circuit breakers.
