We have expertise in the manufacturing and supplying of premier quality Automatic Main Failure Relay-CLA 311 all over India. It is a low end and very cost effective solution system based on latest micro-controller technology for reliability and compactness. The front face is designed to provide simple annunciation with audio and visual representation making it user friendly. The unit fits into a standard 90x90mm panel meter opening.

In automatic mode, the unit monitors 3 phase of the mains voltage and controls the automatic starting, load transfer to generator is running, the device monitors LLOP, High Water, Temperature, Over Speed, Generator Voltage & Frequency and external fault input. Mains Voltages, generator voltage, generator frequency, battery voltage, Gen-set status are displayed in the seven segment LED display, and the units parameters such as time delays and threshold level can be altered at site according to users' requirements via the Push Button on the unit.

Features

• Based on latest micro-controller design for accuracy and reliability.


• All input faults opt-isolated, therefore immune to electrical noise disturbances.


• Site programmable parameters like time delays and voltage and frequency.


• Software interlocking between Mains contractor and Gen set contractor.


• Low fuel indication. Gives warning alarm with visual indication.


• Low battery indication. System automatically checks battery voltage whether 12V or 24V and sets Low voltage level of 10V or 20V respectively. Gives warning alarm with visual indication.


• Suitable for all gen sets ( fuel solenoid type or stop solenoid type.)


• Auto and Manual operation.


• Plug-in connectors for easy replacement and service at site.


• Compact in size. Needs cut out size of 90 x 90mm on the panel front. Bezel size is 96 x 96mm. (T96X96 Din Box).
