Electrical, Specialty Fuses: 170M5249 Application Field and Working Principle

The 170M5249 circuit-breaker combines a quick-change fuse with overload protection and is designed to be used in branch circuits and lighting fixtures. It is designed to prevent fires due to high current as well as overcurrent conditions from occurring. It is designed to protect delicate electrical components, such as computers and motors, as well as the wiring in the circuit. It is rated for 125/250VAC and meets UL-classified standards.

The 170M5249 circuit-breaker has a quick-change fuse, an overload protection system and a time delay function. The quick-change fuse allows for quick and easy installation and provides protection from over-current conditions. The overload protection system ensures that the circuit-breaker will shut off for periods of time if the current exceeds the rated current levels. The time delay function allows for a small amount of power to be available, even while the breaker is tripping, allowing for the eventual shutdown of the equipment.

The working principle of the 170M5249 circuit-breakers is based on the principles of thermal expansion. The overload protection system is designed to detect and react to high currents. When the conductor in the circuit-breaker heats up due to an overload, it expands, causing flow restriction and reducing the current flow. At the same time, the overload protection system trips the circuit-breaker, providing protection. The quick-change fuse provides additional protection from over-current conditions, ensuring that the circuit-breaker trips before any damage occurs to the equipment.

The 170M5249 circuit-breaker can be used to protect equipment and wiring from hazardous over-current conditions. It is also designed to protect delicate electrical components, such as computers and motors, from damage due to over-current or short circuits. The quick-change fuse and overload protection system make it a safe and reliable circuit protective device.

In summary, the 170M5249 circuit-breaker is a UL-classified, 125/250VAC rated circuit-breaker. It combines a quick-change fuse with overload protection and a time delay function. The working principle of the device is based on the principles of thermal expansion, and it is designed to provide protection from hazardous over-current conditions. It has the ability to protect delicate electrical components, such as computers and motors, from damage due to over-current or short circuits.

The 170M5249 circuit-breaker is a reliable and safe circuit protective device that is designed to prevent fires due to high current overloads and short circuits. It is a UL-classified device and is an ideal choice for protecting delicate electrical components as well as wiring in the circuits.
