SPP-5E250

The SPP-5E250 is a specialty fuse designed to protect electrical devices such as motors, transformers, communications devices, and other related equipment. This fuse is used to protect electronic components from excess current or heat, and it works by preventing the flow of too much current. The fuse will trip off when the current flows reaches the approved limit, cutting off the power and preventing damage to the device.

The SPP-5E250 is a surface mount fuse with an integrated thermoplastic resin block containing a solid-state circuit breaker. It has a temperature rating of 690℃ and a breaking capacity of up to 1,000 A. This fuse provides excellent protection against overcurrents, short circuits, and other hazardous conditions. It also has a high resistance to arc fault protection.

The working principle of the SPP-5E250 is relatively simple. When the current passing through the fuse exceeds the rated value or when the fuse is exposed to excessive temperature, the circuit breaker will trip and cut off the flow of current. This protects the device from damage and reduces the risk of a fire or other catastrophic incidents.

This fuse uses a single element, which consists of an arc-fuse plus a thermistor element. When the current passes through the arc-fuse, it acts like a fuse and will break the circuit by melting the element. The thermistor element reacts to the excessive temperature and will act as a trip breaker. Once the temperature of the fuse reaches the threshold, it will also break the circuit.

The SPP-5E250 fuse is ideal for use in many applications, including industrial equipment, lighting, motor control circuits, UPS systems, HVAC systems, electric vehicles, solar panels, charging stations, motors, generators, and many other applications.

The SPP-5E250 fuse is a reliable and cost-effective way to protect against overeating and overheating, and it is suitable for many different applications. It is easy to install and can provide many years of reliable service. It is also an environmentally friendly solution, as it does not generate any hazardous waste or pollutants.
