MP1515 - Duplex 15/15 Circuit Breaker

MP1515 - Duplex 15/15 Circuit Breaker

When you're replacing a circuit breaker in an existing electrical system, getting the details right matters. The Siemens MP1515 is an MH-T duplex circuit breaker featuring two independent 15-amp, 1-pole circuits in a compact configuration. This breaker is made for a specific job: matching the form, fit, and electrical requirements of systems designed to use the MP1515. It's built to last in its intended application and makes no claims beyond its published ratings. Before installation, confirm the catalog number and specifications against the existing equipment, since matching amperage alone does not establish circuit breaker compatibility.

Key Features and Benefits

• Two 15A circuits in one duplex design: The MP1515 contains two individual 15-amp, 1-pole circuits.
• Compact configuration: Each pole uses approximately 1/2 inch of width, for a total breaker width of 1 inch.
• 120V application: Designed for electrical systems requiring the MP1515's 120-volt rating.
• Thermal-magnetic protection: Uses the MH-T thermal-magnetic breaker design specified for this model.
• Flexible conductor range: Suitable for 14–8 AWG copper and 12–8 AWG aluminum conductors.
• Straightforward replacement matching: Well suited to applications where the original equipment calls for the MP1515's specific configuration and ratings.

Material Compliance and Certifications

The MP1515 circuit breaker is UL Listed and CSA Certified, with documented SWD and HACR ratings. Manufacturer data also classifies it as non-dangerous goods. The supplied specifications don't include RoHS compliance information or a SCIP number, so it doesn't make claims about those items that the available product data doesn't support.

Where It Works Best

The MP1515 15/15 amp duplex circuit breaker makes the most sense when you're working with a compatible residential load center that specifically requires this breaker configuration. It's especially relevant for maintaining existing or legacy electrical systems where matching the original MH-T duplex design, 15/15A rating, 120V rating, 10 kA interrupting capacity, physical dimensions, and conductor requirements is important.
