LA070URD30TTI0080 is an electrical specialty fuse. As its name implies, it is specific to its application field and features a unique working principle.

The LA070URD30TTI0080 is an IEC class L fuse that is UL Recognized. It has a rated current of 70A, an interrupting rating of 200 KA, and a rated voltage up to 415V. It is designed for use in higher power circuits such as switching loads and motor circuits in circuits with low interruption ratings. The IEC class L designation, combined with the UL marking, provides for reliable protection of personnel, equipment, and property in the event of an overload or short circuit within the protected circuit.

The LA070URD30TTI0080 fuse has a unique construction which provides a number of benefits over other fuses. Its design consists of two plastic chambers which are sealed together. Inside one of the chambers is a bi-metallic strip which is connected to an epoxy-glass channel that contains a metallic particle. When the current flows through the fuse, a small amount of heat is generated by the electrical resistance of the metal particle. This heat is transferred to the bi-metallic strip which then expands, breaking the connection between the two chambers and thus cutting off the power to the protected circuit.

The LA070URD30TTI0080 fuse operates at an interrupting rating of 200KA, which is two to four times the current rating compared to regular fuses. This allows for higher current rating and greater protection from overcurrent and short circuits. The fuse also features a time delay operating principle which gives additional protection against nuisance tripping of the circuit breaker.

The fuses design is also highly resistant to breakage, making it a reliable form of protection. The narrow cross-section of the fuse casing and chamber prevents the physical damage sustained by other fuses. This also makes the fuse more resistant to corrosion and mechanical vibration. In addition, the design of the epoxy-glass channel also protects against dangerous condensation from forming.

Overall, the LA070URD30TTI0080 fuse is an effective way to protect equipment, personnel, and property from overloads and short circuits. Its unique construction and time delay operating principle provide superior protection and reliability. This particular design is highly resistant to mechanical shock and vibration, corrosion, and other damage.
