MP120AF - 20 Amp Circuit Breaker

MP120AF – 20 Amp Circuit Breaker

Introducing the MP120AF – 20 Amp Circuit Breaker, a dependable single‑pole, thermal‑magnetic trip device built to deliver long-lasting overcurrent and arc-fault protection in residential, commercial, and light‑industrial wiring systems. Designed with the latest AFCI (Arc Fault Circuit Interruption) technology, this circuit breaker helps you guard your electrical installations against hazardous arcing that can trigger fires — giving you peace of mind and a safer environment for your home or workspace.

Key Features and Benefits

• Arc-Fault Circuit Interruption (AFCI): By detecting and interrupting dangerous arc-fault conditions, the MP120AF significantly reduces the risk of fire caused by wiring faults, worn insulation, or loose connections.
• Thermal-Magnetic Trip Mechanism: The dual-action trip design ensures reliable protection by responding to both overloads (with thermal sensing) and short circuits (via magnetic sensing), which helps prevent damage to wiring and connected devices.
• Consistent Performance at Elevated Temperatures: Calibrated for 40 °C operation, this breaker maintains reliable functionality even when ambient temperatures rise, offering dependable protection in a variety of settings.
• Easy Integration: Compact, single-pole form factor makes installation straightforward — ideal for retrofits or new wiring jobs where space and load balancing matter.
