MP1520 - Duplex 15/20 Circuit Breaker

MP1520 - Duplex 15/20 Circuit Breaker

When you're replacing a breaker in an existing load center, the catalog number, electrical ratings, and physical configuration all matter. The Siemens MP1520 is an MH-T duplex circuit breaker that combines one 15-amp, 1-pole circuit and one 20-amp, 1-pole circuit in a compact 1-inch-wide assembly.

Key Features and Benefits

• 15A and 20A circuits in one duplex breaker: Combines one 15-amp and one 20-amp, 1-pole circuit in a single assembly.
• MH-T duplex design: Made for applications that specifically call for this breaker type and configuration.
• Compact construction: Uses 1/2 inch of width per pole, with an overall breaker width of 1 inch.
• 120V rating: Designed for compatible 120-volt applications.
• Thermal-magnetic circuit protection: Uses the thermal-magnetic design associated with the MH-T breaker type.
• Copper and aluminum conductor compatibility: Accepts 14–8 AWG copper and 12–8 AWG aluminum wire.
