170M4181

The 170M4181 is a specialty fuse manufactured by Bussmann that offers high speed fault protection, which helps to reduce downtime in heavily used electrical systems. The 170M4181 is designed to be used as an auxiliary protection with a slow-blow fuse or circuit breaker. The main function of the 170M4181 is to provide current limited protection from short circuit currents up to 5000A. This short circuit protection is typically used when the main protection is a slow-blow fuse or circuit breaker.

The 170M4181 is a high-speed, Class L fuse, rated at 500V and 500kAdc max interrupting rating. It features an all-ceramic frame and two pieces of silvered wire as the fuse element. It is UL approved and IEC approved for protection against overcurrent and short-circuit protection. The fuse meets or exceeds the requirements of ANSI, UL 98, and IEC 60934.

The working principle of the 170M4181 is based on the concept of current limiting. When a short circuit or overcurrent fault occurs, the fuse element doubles over the fault current for a few milliseconds, allowing the current to be limited to protect downstream components from damage. The fuse element then melts, completely disrupting the fault current. When this happens, the fault is contained, and the fuse speeds the restoration of power to the protected circuit.

The 170M4181 has a wide range of applications in numerous fields, especially in areas requiring high reliability and safety. It can be used in automotive, industrial, and residential applications. The 170M4181 can also be used in power supplies, battery chargers, motors, transformers, and other applications where current-limited protection is required. It can also be used in overload, short-circuit, and reverse polarity protection.

The 170M4181 is a reliable, fast-response fuse capable of efficiently protecting the downstream components of a power system. It is designed to provide low-resistance fault protection, high speed operation, and is UL approved for overload and short-circuit protection. The 170M4181 is used in a wide range of applications such as automotive, industrial, and residential, and is an ideal choice for surge protection.
