Murray MP120 20-Amp Single Pole Circuit Breaker - Type MP-T Thermal Magnetic Protection

Homeowners and electricians, when you need to replace a tripping breaker or add a new circuit, this Murray MP120 is exactly what you're looking for.

This 20-amp single pole breaker provides reliable thermal-magnetic protection for your home's electrical system.

The 10,000 AIC interrupting rating means it can handle serious fault currents, while the time-saving Insta-Wire feature makes connections quicker and easier.

It's designed specifically for Murray load centers and meter combinations, and using genuine Murray breakers ensures you don't void your panel's warranty.

These are 120V rated and work in single or 3-phase systems.

The thermal protection guards against overloads (like too many devices on one circuit), while the magnetic protection kicks in instantly during short circuits.

Whether you're replacing a faulty breaker, adding circuits for a renovation, or keeping spares on hand for emergencies, having the right breakers is crucial for electrical safety.

Remember - never use used breakers in your panel, as Murray specifically warns this voids warranties.

The MP-T design plugs securely into Murray panels and provides that reliable protection your home's wiring needs.

From kitchen appliance circuits to workshop outlets, this 20-amp breaker handles the loads that power your daily life while keeping your electrical system safe from potential hazards.

For DIYers comfortable with electrical work or professionals stocking their truck, this is the genuine part that ensures proper protection and compliance with electrical codes.
