C1S 750 Circuit Protection

C1S 750 application field and working principle

C1S 750 is a fuse approved by UL and CSA and can be used either in the US and Canada. It is designed to be a reliable way of protecting sensitive components and circuits from damage caused by excessive current. It operates by forming a temperature-sensitive element that expands when heated and breaks the circuit.

It is commonly used to protect circulators, transformers, generators, motors and cables. There are many areas where it is especially useful, including in telecom base stations, mobile phone base stations and digital switching systems. C1S 750 is used to provide protection for a variety of devices and equipment, including computers, televisions, radios, circuit boards and many other types of electronic equipment. In addition, it can also be used in boilers, pumps and air conditioners, as well as in renewable energy systems.

The C1S 750 fuse is a single-pole, time-delay type fuse and works by breaking the circuit during an overload or short circuit. When the current reaches the overload rating of the fuse, an excessive current heats the thermal element and causes it to open. This activates a spring-loaded plunger that pushes a spring-loaded arm. This arm then lifts the breaching contacts and opens the circuit.

The C1S 750 fuse operates in two distinct stages. The first stage is called the “I2t” stage, which is the time required for the current to reach the overload rating. The second stage is called the “hold” time, which is the amount of time required for the overload rating to remain steady. The hold time can be adjusted by changing a solenoid coil connector or by setting a dial.

The application field of the C1S 750 fuse is extremely broad. It is commonly used in electric motors, circuit breakers, transformers, air conditioners, computer systems, electric generators, pumps, televisions, radios and many other types of electronic equipment. Additionally, its ability to offer protection against overcurrent makes it a valuable tool in the protection of sensitive electronic components, thus providing greater reliability and safety.

The working principle of the C1S 750 fuse is relatively simple. When the overload current reaches the specified rating, it causes the temperature-sensitive element to expand and break the circuit. This creates an open circuit that prevents further current from flowing, thus providing protection for sensitive components and circuits.
