MP120 - 20 Amp Circuit Breaker

MP120 - 20 Amp Circuit Breaker

The MP120 is a durable 20-amp, 1-pole circuit breaker for 120V applications, featuring a thermal-magnetic design and a 10k interrupt rating. When you're selecting a replacement for existing or older equipment, match not just the appearance but key specifications such as amperage, pole count, voltage, and interrupt rating.

Key Features and Benefits

• 20 Amp Rating: The MP120 carries a 20A continuous current rating, an essential specification when checking a replacement.
• Single-Pole Design: Its 1-pole configuration should match compatible electrical equipment requiring the same arrangement.
• 120V AC Rating: Rated for 120V AC applications.
• Thermal Magnetic Circuit Breaker: Uses the specified thermal magnetic breaker design for circuit protection.
• MP-T Design: The MP-T designation provides a key reference point for checking form, fit, and functional compatibility.
• 50/60Hz Operation: Rated for electrical systems operating at 50/60Hz.

Where It Works Best

The MP120 20 amp circuit breaker is best considered when maintaining compatible existing or legacy electrical equipment that calls for its specific electrical and physical characteristics. A replacement check should go beyond amperage alone. Confirm the MP-T design, 20A continuous current rating, 1-pole configuration, 120V AC rating, 10k interrupt rating, 50/60Hz frequency rating, and 40°C maximum operating ambient temperature against the requirements of the equipment.
