Protection Relays & Systems involve an array of components and functions that are used to ensure the electrical distribution system remains safe and reliable. The 901X range of overcurrent relays and system protection devices have been designed to provide a cost-effective solution for utilities and industries to safeguard their facilities against traditional and transients overcurrents.

The 901X range of protection relays features a current transformer and sensing element combined with electrical circuitry to constantly monitor the system for any high or low currents and take appropriate protective action. The 901X range offers a full line of compact relay models with fixed pickup settings, adjustable relays with manual or automatic reset, and electronic time overcurrent relays with binary inputs.

The 901X relays are designed to provide fast and reliable overcurrent protection for electrical power systems. The 901X offers secure and sensitive protection of circuit breakers and other electrical components by detecting overcurrents in two levels. The first level provides instantaneous protection that operates to remove potential hazards immediately, while the second level offers time-delay protection that is less sensitive than the first level, but allows a longer period of time for the system to autonomously reset.

The 901X relays can be used in a wide range of applications such as power plants, distribution systems, industrial equipment, motors, generators, and electric industrial automation control systems. It can be used in combination with other protection relays to provide additional protection against external short-circuits, over-voltage, over-current and other fault conditions. The 901X relays can also be used with transmission and process control systems to provide comprehensive protection against unacceptably high or low current levels that could cause damage to the system or cause it to shut down.

A key feature of the 901X relays is their user-friendly interface, which allows them to be easily programmed and monitored for proper operation. The relay’s status can be read from dedicated remote terminals, and its settings can be adjusted without having to power down the system. This user-friendly design also helps ensure the system remains safe and reliable for years to come.

The 901X range of protection relays and system protection devices provide a cost-effective and secure protection for a wide variety of electrical systems and components. When used together with other protection relays, these relays provide superior protection against external short-circuits and other fault conditions. The 901X range of relays are user-friendly and offer fast and reliable operation.
