MP115 - 15 Amp Circuit Breaker Description
MP115 - 15 Amp Circuit Breaker
The MP115 is a 15 amp, 1-pole thermal magnetic circuit breaker with a 120V rating and 10k interrupt rating, intended for compatible electrical equipment requiring the MP-T configuration. When you're sourcing a replacement breaker for existing or legacy equipment, the catalog number is only the starting point. The amperage, pole count, voltage, interrupt rating, breaker type, and equipment compatibility must all align. When selected, installed, and maintained correctly for its intended electrical application, its solid construction is built to last.
Key Features and Benefits
- 15 Amp Rating: Rated for 15A continuous current, making it easy to verify against existing circuit requirements.
- Single-Pole Design: The MP115 is a 1-pole breaker, an important physical and electrical compatibility point when identifying a replacement.
- 120V Rating: Specifically rated for 120V applications.
- Thermal Magnetic Circuit Protection: The supplied product information identifies the MP115 as a miniature thermal magnetic circuit breaker.
- MP-T Configuration: The MP-T designation gives technicians and buyers another key identifier when checking compatibility with existing equipment.
- 50/60Hz Operation: Rated for operation at both common power frequencies.
- 40°C Maximum Operating Ambient: Provides a defined temperature specification for application checks.
