Phase: 3

Electricity Type: Ac

This is an intelligent multi-functional monitoring and protection device which including timing, counting and voltage display, overvoltage undervoltage protection, phase failure protection and phase sequence protection functions. Made of industrial microprocessor chip and nonvolatile storage technology. LCD display which is easy to read and operate. The device can display the current supply voltage, record working times, working hours, number of fault, failure time/period and other working data. The relay will cut off the power to protect the equipment when over-voltage, under-voltage,phase failure or phase sequence happens in 3 phase power system. It is widely used in passenger elevator, hoist , machine tool and other equipmentswhich are frequently started. Protecting the equipment and human safety. Applications:1. Control for connection of moving equipment (site equipment, agricultural equipment, refrigerated trucks). 2. Control for protection of persons and equipment against the consequences of reverse running (lifting, handling, elevators, escalators, etc.). 3. Control of sensitive 3-phase supplies. 4. Protection against the risk of a driving load (phase failure)./Phase loss protection 5. Normal/emergency power supply switching. FeaturesMain functions features:1. Voltage display: Show current supply power voltage value2. Over-voltage & under-voltage protection: When the power supply voltage is too high or too low, the power would be cut off(Over and under-voltage value can be set) 3. Phase failure protection: The equipment power will be cut off when phase failure/Loss happens in 3 phase power 4.Phase sequence protection: When fault happens in the rotational direction of phases,the power supply will be cut off 5. Timing and Counting: Recording starting times and total working hours of equipment 6. Fault record: Record faults happen times and total hours Technical DataDiagram of the Phase Protection Relay:Wiring DiagramCode Table: This voltage protector mainly used for residential household box entry or over-voltage,under-voltage or over-current protection of distribution lines for single-phase electrical equipment. BOA-40 type multi-function Protective Device is designed to measure single phase two wire AC active energy and used in overvoltage protection, under voltage protection and over-current protection . In case of over-voltage fault, under-voltage fault or over-current fault in line, this product can instantly power off the load to prevent electrical equipment from being burnt. The over-voltage, under-voltage and over-current values of this product can all be set up by yourself and can be adjusted on the basis of local practical condition .It is a long use-life product with the advantage of high stability , highover load capability , low power loss and wide working voltage range . Features: 2.1 LCD display with backlight , can display total active energy (kWh) , real time current (A) , voltage(V) , active power (W) .2.2 LCD display kWh (4 digital+1 decimal) , Bi-directional total active energy measurement ,reverse active energy measure in the total active energy2.3 Product self-design has function of lighting protection2.4 Overvoltage protection, under voltage protection and over-current protection can select auto-Reclosing mode or manual--Reclosing mode2.5 In case of over-voltage fault, under-voltage fault or over current fault in single phase line, the product can power off the line and can automatically restore connecting the line over a time delay after voltage of the lien is recovered to normal condition.2.6 In case of transient over voltage in line, the product can protect the equipment from false operation.2.7 In case that the line subjects to unstable voltage or sudden power-off and power-on due to loosened connection and other fault, the product will disconnect the line.2.8 When fault voltage of the line reaches the peak, the product itself will not be damaged.2.9 Under over-current protection mode , you also can select Malignant load protection (Pure Resistive Load limit) which is used for Apartments and Student Dormitories electric safety2.10 You can select the circuit output cycle switch on/off mode2.11 Led indication of overvoltage protection, under voltage protection and over-current protection2.12 Diversified design for the protection , you can closed t any one of overvoltage protection, under voltage protection and over-current protection in any time
