MPP2125KH - 125 Amp Circuit Breaker

MPP2125KH  - 125 Amp Circuit Breaker

The MPP2125KH is a 125A, 4-pole, 120/240V Type MPP-HT main circuit breaker for electrical distribution equipment requiring this specific breaker configuration. Its product designation identifies a 125A rating and 22K interrupt rating, while the technical overview also specifies thermal-magnetic operation and a plug-in connection. If you're replacing a breaker in existing or legacy equipment, matching the catalog number matters, but the full specification matters just as much.

Key Features and Benefits

• 125A product designation — The catalog description identifies the MPP2125KH as a 125-amp breaker; however, the separate technical overview lists 25A, so verify the actual rating before use.
• 4-pole configuration — Provides a clear pole arrangement to match existing electrical distribution equipment.
• 120/240V voltage rating — Designed around the voltage specification stated in the supplied manufacturer data.
• Type MPP-HT — Gives maintenance personnel and buyers a specific breaker type to compare with an existing component or equipment documentation.
• Thermal-magnetic trip operation — The technical overview identifies the breaker as using a thermal-magnetic trip configuration.
• Plug-in connection — Connection type is specified as plug-in, an important form-and-fit consideration during replacement.

Material Compliance and Certifications

The supplied technical overview identifies UL 489 as the applicable standard for the MPP2125KH. The available information does not explicitly state additional third-party certifications, so assume none beyond what is documented for the exact breaker.

Where It Works Best

For existing or legacy electrical distribution equipment requiring the MPP2125KH form factor and a Type MPP-HT, 4-pole, 120/240V, thermal-magnetic, plug-in main breaker configuration, this catalog number provides a precise starting point for a replacement compatibility check. Evaluate it as a form, fit, and functional replacement rather than matching it by appearance or catalog number.
