Siemens MP1520 Tandem Circuit Breaker 15/20A 1P 120V

Product Description

The SIEMENS MP1520 is a tandem circuit breaker rated for 15 and 20 amps on a single pole at 120 volts, designed for use in residential and light commercial electrical panels. This dual-function breaker fits into a single panel slot while providing two independent circuit protection positions, making it a practical solution when panel space is limited. Licensed electricians install this breaker during panel upgrades, service changes, or circuit additions where the load center supports tandem-style devices. It provides standard overcurrent protection and trips automatically on overload or short-circuit conditions.

The MP1520 is suited for residential load centers that accept tandem breakers in designated slots. Typical applications include adding circuits for lighting, outlets, or small appliances without replacing the panel. It is commonly installed during remodel work, panel capacity expansions, or service upgrades where a full-size single-pole slot is not available but additional circuits are required. Always verify the load center's tandem-acceptance chart before installation to confirm slot eligibility.

Key Features

• Dual circuit protection in a single panel slot — 15 amp and 20 amp positions on one pole
• 120 volt rated for standard residential and light commercial branch circuit use
• Single-pole tandem configuration saves panel space during expansions or upgrades

Compatibility

Designed as an OEM-style replacement or addition for residential and light commercial load centers that support single-pole tandem circuit breakers. Verify panel compatibility using the load center manufacturer's tandem-acceptance chart before installation.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NFPA 70 (NEC) requirements. De-energize the panel at the utility disconnect and verify zero voltage with a calibrated meter before handling any bus bar connections. Confirm the target panel slot is rated to accept tandem breakers before seating the device. Do not force the breaker into a slot not designated for tandem use.
