Collection: 1-Pole Circuit Breaker
Description:
A 1-pole circuit breaker is a type of electrical protection device designed to control and protect a single hot wire in an electrical circuit. It safeguards against overcurrent, short circuits, and electrical faults by interrupting the flow of electricity when a fault is detected. These circuit breakers are commonly used in residential, commercial, and industrial electrical systems to protect circuits with lower voltage and current demands.
Applications of 1-Pole Circuit Breakers:
Residential Electrical Systems: Protect individual branch circuits like lighting, outlets, and small appliances.
Commercial Spaces: Used in low-load circuits for lighting, small machinery, and office equipment.
Industrial Equipment: Protects low-power, single-phase equipment like pumps, fans, and motors.
Solar and Renewable Energy: Used in photovoltaic (solar) systems to protect DC circuits.
Control Panels: These are found in industrial and automation panels to protect low-power control circuits.
Portable Generators: Protects circuits in portable or backup generator systems.
