What types of SPDs are available for single-phase systems?

SPDs for single-phase systems come in several types:

• Type 2 SPDs: These are commonly installed at the main distribution board to protect against surges from indirect lightning strikes and switching operations.
• Type 3 SPDs: These provide additional protection at the point of use, such as individual sockets or equipment, and are often used in conjunction with Type 2 SPDs for comprehensive protection.
