Which type of circuit breaker is typically rated for small loads?

The type of circuit breaker that is typically rated for small loads is the miniature circuit breaker. Miniature circuit breakers (MCBs) are designed to protect electrical circuits from overload and short-circuit conditions. They are commonly used in residential and light commercial applications to safeguard small circuits, such as lighting and power outlets, because they provide reliable protection without taking up significant physical space.

MCBs are characterized by their compact size and sensitivity to small changes in current, making them well-suited for handling smaller loads effectively. Their rating typically ranges from 1 ampere to 100 amperes, making them ideal for individual circuits that do not exceed these capacities.

In contrast, air circuit breakers are designed for larger load capacities and higher voltage applications. Hydraulic circuit breakers are used in higher power applications and often in industrial settings. Dual function circuit breakers offer both overload and ground fault protection but do not specifically target small loads like miniature circuit breakers do. Thus, the miniature circuit breaker stands out as the preferred choice for small load applications due to its specific design and function.
