170M5446

The 170M5446 application field and working principle is suitable for working at 120-600V AC and up to 45kA short-circuit current protection. The unique thermal disconnecting system of this fuse provides the highest level of protection for electric motor circuits. With the wide range of characteristics available, the fuse can provide fast and reliable protection of motor circuits in a variety of applications.

The 170M5446 fuse is a thermal-magnetic type device with an electrical contact system that incorporates a thermal disconnecting system. The integrated thermal disconnecting system is designed to provide additional protection to the motor circuit by allowing the fuse to open at a predetermined threshold. The thermal disconnector will open after the high temperature has been detected, thereby providing additional protection for any potential short-circuits.

The fuse is also designed with a unique mechanical latch system that allows it to be pushed and physically locked in the open position. Once the current reaches the threshold level, the latch will release allowing the fuse to reset. This design ensures that the fuse will not remain open if the fault has been removed, and will reset automatically when the fault has been removed.

In addition, the 170M5446 fuse is also designed with a thermal element that is able to detect high temperature levels within the motor circuit. When a high temperature level is detected, the built-in thermal disconnector will open and the fuse will trip, providing additional protection for the motor circuit. This additional protection ensures that any potential short circuits are detected and the motor will be shut off before further damage can be caused.

The design of the 170M5446 fuse also allows it to be used in applications that require different current ratings. The 180A, 200A, and 250A versions of this fuse provide low amperage protection and the 700A version provides higher amperage protection for larger motor applications. The 150 and 200 Amp versions can be used for disconnecting short-circuits in motor circuits up to 250 Amps.

Overall, the 170M5446 fuse provides an excellent level of protection for electric motor circuits with a wide range of characteristics and a thermal disconnecting system. With its unique thermal disconnecting system, the fuse can provide a reliable and fast protection for motor circuits in a variety of applications.
