Abb 100a tpn earth leakage breaker

A very specific question!

The "ABB 100A TPN Earth Leakage Breaker" is a type of electrical protection device manufactured by ABB (Asea Brown Boveri), a leading global company in the field of power and automation technology.

Here's a breakdown of the components:

• "ABB" is the manufacturer's name.
• "100A" refers to the maximum current rating of the device, which is 100 amperes (A).
• "TPN" stands for "Trip and Protect Network", which is a type of earth leakage protection system developed by ABB. This system is designed to detect and interrupt earth faults in electrical installations.
• "Earth Leakage Breaker" is the type of device, which is designed to detect and interrupt earth faults (also known as ground faults) in electrical installations.

In summary, the ABB 100A TPN Earth Leakage Breaker is a device that detects and interrupts earth faults in electrical installations, with a maximum current rating of 100 amperes. It is part of ABB's Trip and Protect Network system, which is designed to provide reliable and efficient earth leakage protection.
