They are a safety mechanism designed to open or break the circuit in the case of overload. They are usually used when a device on the circuit would be damaged or destroyed by an overload.
For 220v circuits
Fuses, fuseable links and circuit breakers.
Remove the two twenty amp breakers from the regular size slot and install two mini amp breakers. A mini amp breaker has two breakers per regular size slot.
The different types of circuit breakers available in the market include thermal-magnetic, magnetic, and residual current devices (RCDs). These circuit breakers are designed to protect electrical circuits from overloads, short circuits, and ground faults.

Electrical circuits are protected by: 1) Fuses 2) Circuit Breakers and/or 3) Fusable links
Breakers can trip due to overloading, short circuits, or faulty wiring. It is important to identify the cause and address it to prevent further issues.
household circuit comprises of main swith,circuit breakers,wires and control switches.
Fuses and circuit breakers are used to protect the wiring and devices from overload and heating caused by short circuits, short circuits that, if unprotected, could cause major damage and/or fire due to excessive current.
There is a heated bimetallic strip that provides a time delay small overload protection. When its contact makes, it energizes a coil to trip the breaker. Some breakers are mechanical, though. There is a coil that trips the breaker instantly on large overload.
An electrical load center, also known as a circuit breaker panel or distribution board, is a central point where incoming electrical power is divided and distributed to multiple circuits within a building. It typically contains circuit breakers or fuses to protect the circuits from overloading and short circuits.
You can swap a single breaker for two mini breakers or you can add a sub-panel. If you only need a couple of extra circuits then just add mini-breakers.
