What are the two basic mounting types of conventional circuit breakers?

The two basic mounting types of conventional circuit breakers are snap-in and bolt-in. Snap-in circuit breakers are designed to be easily installed by snapping them into a panel, making them suitable for applications where quick service and replacement are necessary. This type of mounting allows for a more flexible and efficient installation process, particularly in environments that require frequent changes or upgrades to the breaker panel.

Bolt-in circuit breakers, on the other hand, are mounted securely using bolts, providing a more robust and permanent installation. This type is often used in larger systems or where enhanced durability and reliability under high current loads is essential.

Understanding the differences between these mounting types helps technicians choose the correct breaker for their specific application, taking into account factors such as ease of installation, maintenance requirements, and system design.
