The 5TTP 3-R is a multifunctional fusing device that combines a fuse, surge arrester, and differential protection in one unit. The device can be used to protect electronic and electrical equipment from over-voltage surges and spikes that can cause damage. It also provides differential protection with built-in voltage-sensing relays.

The 5TTP 3-R is used in power system protective relaying and industrial control applications. It can be used for primary main protection, secondary backup protection, and tertiary control protection. The design includes a built-in fifth trip level protection, where if the voltage reaches a certain level, it will automatically trip and shut off the power.

The 5TTP 3-R has a fuse element that will react quickly and effectively in the event of an over-current occurring on the system. The surge arrester element provides protection against power surges. The differential protection element is used to protect the system from ground faults. Additionally, the built-in voltage-sensing relays provide differential protection to ensure all phases are operating within the designed parameters.

The working principle behind the 5TTP 3-R is similar to other fusing devices. An over-current is detected using the fuse element, which then triggers the over-voltage protection element to trip and shut off the power supply. This helps prevent damage from any over-voltage or over-currents that may occur on the system. The surge arrester is used to protect against power surges and the differential protection element senses ground faults and trips the circuit if needed.

The 5TTP 3-R is a highly reliable and cost effective protection and control system for power systems. It is an ideal device to protect and control the operation of electronic and electrical equipment in industrial applications. It is also an essential component of any system that requires reliable protection and control of electronic and electrical equipment.
