General Electric TMQB2180 80A 2-Pole 240 V Circuit Breaker

Meet the General Electric TMQB2180 80A 2-Pole 240 V Circuit Breaker—a dependable, two-pole overcurrent protection device designed for serious 240-volt circuits. With an 80-amp current rating and dual poles, this breaker interrupts both hot legs to safeguard wiring and connected equipment from overloads or short circuits. The part number TMQB2180 ensures precise replacement and easy inventory for maintenance and upgrades.

What it does

When a 240 V circuit draws beyond 80 A, the TMQB2180 trips, cutting power to the circuit and helping prevent insulation damage, overheating, and potential fire hazards. Its two-pole design ensures simultaneous interruption of both legs, maintaining balanced protection for multi-wire circuits.
