What are the two types of circuit protection devices?
There are two general categories of circuit protection: 1) Fuses 2) Electro-mechanical circuit breakers. Each has its advantages which will be discussed here. Fuses break down into three convenient categories —fast-blow, slow- blow, and semiconductor. Each responds to fault current in different ways.

What are the types of overload cut out devices available?
The designer has many overcurrent protection devices to choose from. The two most common are fuses and circuit breakers. Many circuit breakers are also known as molded case breakers or MCBs. Fuses: A fuse is the simplest form of overcurrent protective device but it can be used only once before it must be replaced.
How do overcurrent protection devices work?
An overcurrent protection device protects the circuit by opening the device when the current reaches a value that will cause an excessive or dangerous temperature rise in conductors. Most overcurrent protection devices respond to both, short-circuit or ground-fault current values as well as overload conditions.
What is the overload protection?
Overload relays protect the motor, motor branch circuit, and motor branch circuit components from excessive heat from the overload condition. Overload relays are part of the motor starter (assembly of contactor plus overload relay). They protect the motor by monitoring the current flowing in the circuit.
