Collection: 2-Pole Circuit Breaker

Description:

A 2-pole circuit breaker is an electrical safety device designed to protect circuits carrying two "hot" wires in a single-phase or three-phase system. It is typically used for higher-voltage circuits, such as 240V in residential systems or specific commercial and industrial setups applications. Simultaneously disconnecting both poles (wires) during a fault or overload, ensures safety and prevents electrical hazards.

Applications of 2-Pole Circuit Breakers

Residential:
Used in 240V circuits for appliances like:

Electric water heaters
Air conditioners
Electric stoves and ovens
Clothes dryers
Commercial: Protects circuits in office buildings or retail spaces for equipment requiring higher voltages or power, such as HVAC systems or elevators.
Industrial: Essential in protecting motors, heavy machinery, and equipment that operate on higher voltage and require dual-phase connections.
Renewable Energy Systems: Used in solar inverters and battery systems to manage and protect circuits carrying higher voltages.
Data Centers: Protects circuits powering high-performance servers and other equipment requiring stable, high-voltage power supplies.
Portable Generators: Used to protect generator circuits providing 240V power for temporary setups.
