MPP2225KM - 25 Amp Circuit Breaker

MPP2225KM - 25 Amp Circuit Breaker

When you’re replacing a breaker in older electrical distribution equipment, the catalog number and electrical details matter far more than sales language. The MPP2225KM is identified in its primary product designation as a 225A, 4-pole, 120/240V Type MPP-MT circuit breaker with a 65K interrupt rating. It uses a thermal-magnetic trip and plug-in connection, and the supplied specifications list UL 489 as the applicable standard. This breaker is associated with load center main and feeder circuit-protection applications. For maintenance work on legacy equipment, the goal is simple: match the original breaker as closely as the equipment requires. These breakers are built to last, but correct form, fit, and electrical compatibility still come first.

Key Features and Benefits

• 225A primary designation: The main product description identifies the MPP2225KM as a 225-amp circuit breaker.
• Four-pole configuration: Provides the four-pole arrangement specified for this catalog number.
• 120/240V rating: Intended for equipment requiring the stated 120/240V electrical configuration.
• Type MPP-MT: An important identifier when matching an existing breaker for form, fit, and function.
• Thermal-magnetic trip: Uses the trip method stated in the supplied technical data.
• Plug-in connection: Connection style is clearly identified, making it easier to compare against the breaker being replaced.
• Marine 50C feature: Listed as a special feature in the supplied product specifications.

Material Compliance and Certifications

The supplied specifications identify UL 489 as the applicable standard for the MPP2225KM.

Material-compliance information is more limited. RoHS compliance is listed as not available, and a SCIP number is not available. The source data references REACH Article 33 information, but provides no specific compliance determination. WEEE take-back obligations are listed as No.

Where It Works Best

The MPP2225KM is most relevant when servicing existing or legacy electrical distribution equipment that calls for this specific breaker configuration. That means checking for a Type MPP-MT breaker with four poles, a 120/240V rating, a thermal-magnetic trip, a plug-in connection, and the specified interrupt rating.
