What are fuses & circuit breakers?
Fuses and circuit breakers may also be installed in equipment such as your automobile to protect against internal faults. Figure 2–29 shows a variety of fuses and breakers. Fuses use a metallic element that melts when current exceeds a preset value. Thus, if a fuse is rated at 3 A, it will “blow” if more than 3 amps passes through it.
What are striker fuses?
Striker fuses are fuses fitted with a spring-loaded striking device that can trip adjacent switches and also indicate that a fuse has blown. A Type C fuse is actually a type of miniature circuit breaker (MCB). MCBs are a type of circuit breaker used with lower-powered circuits to cut off current in the event of an overload.
What is a fuse & how does it work?
A fuse is an electrical component designed to protect electrical circuits by safely opening the circuit under abnormally high current loads. Fuses come in many shapes and sizes, but each one is designed to protect a circuit with a specific set of electrical parameters.
What is a Type C fuse?
A Type C fuse is actually a type of miniature circuit breaker (MCB). MCBs are a type of circuit breaker used with lower-powered circuits to cut off current in the event of an overload. Type C fuses trip circuits when the current exceeds the rated one by between five and ten times - i.e. at 100-500 amps for a 20amp device.
Why are fuses a cost-less solution for overcurrent protection?
Fuses are cost-effective compared to other protective devices such as circuit breakers, making them a cost-less solution for overcurrent protection. Fuses provide quick protection against electrical defects by rapidly interrupting circuit current in the case of an overcurrent condition.
Which type of Fuse is suitable for AC 50Hz?
This series of cylindrical fuse is suitable for AC 50Hz, rated voltage to 500V, rated current to 125A. It is mainly used for protecting the electrical circuit against overload
