Omron K6EL, K6EL-500 Manual
Omron K6EL-500 is a high-speed, compact ground fault relay designed for use in low-voltage circuits. It features a selectable operating time of less than 0.1 seconds and is engineered for high reliability, even when working with inverter loads. The K6EL-500 offers flexibility with its switchable sensed current, allowing you to adjust sensitivity based on your specific application requirements. For remote monitoring, the automatic-reset models provide continuous fault detection and alert you to potential issues. The K6EL-500 is compatible with a range of through-type ZCTs (Zero-phase Current Transformers), simplifying installation and ensuring seamless integration into your electrical system.

Change the current using the slidac and ascertain the K6EL’s operating value each time by reading the ammeter. For example, R could take the values shown below: 30 mA: 3.3 k:, 6 W 100 mA: 1 k:, 20 W Safety Precautions ■ Correct Use Switching the Operating Time Installation and Wiring • Do not, under any circumstances, connect the ZCT’s output terminals k and l to ground. Doing so may result in damage to the Relay’s internal circuits. • Pass the primary conductor through the ZCT once. • The Relay detects ground faults in internal wiring of devices due to insulation deterioration and so install the ZCT as close to the power supply side as possible. 1. With the K6EL-A100, A200, and A500, the operating time can be switched using a flat-bladed screwdriver. 2. The operating time for the K6EL-30, 100, 200, 500, R50, and R500 is fixed and hence cannot be switched. ZCT Installation • Install the ZCT at an outdoor cable inlet or on a ground bus bar at a location allowing easy inspection. • When installing on the electrical path, use a ZCT with a value greater than the electrical path’s rated current. • If the secondary lines run in parallel to a circuit carrying a large current, either separate the lines as far as possible or use a shield line. Run the secondary lines close to each other. Sensed current selection switch Operating time selection switch Testing ZCT K6EL Primary conductor Separate by 20 cm min. Circuit carrying large current • When installing a separate-type ZCT with current flowing along the primary conductors, short the secondary terminals using clips or some other method. Switching the Sensed Current • If the ground fault indicator (red) lights when the Relay’s test button is pressed, it means that the internal circuits are operating normally. • To make an overall test, run a simulated ground fault current. Resetting • Once manual-reset models operate, they continue to operate until they are reset. Reset them either by pressing the reset button (black) or by turning the control power supply OFF and ON again. • Automatic-reset models reset automatically when the ground fault is cleared (i.e., the current drops below the sensed current). 1. With the K6EL-@100, 200, 500, R50, and R500, the sensed current can be switched using a flat-bladed screwdriver. 2. The sensed current for the K6EL-30 is fixed and hence cannot be switched. http://www.ia.omron.com/ (c)Copyright OMRON Corporation 2007 All Rights Reserved. 10 K6EL Q&A Q: How does the K6EL operate when used for inverter loads (e.g., inverter motors and inverter air conditioners)? A: The influence of high-frequency noise generated by the inverter has been reduced by combining a special ground fault relay IC and a capacitor for cutting out high-frequencies. The possibility of malfunctions due to the influence of the inverter is much less than with the existing ESA Ground Fault Relay. R S M Inverter T Rg K6EL Q: What connection method should be used for ungrounded electrical paths? A: With ungrounded electrical paths, connect the capacitor or resistor for detection in the way shown in the diagram. The table shows the formulas for calculating the resistance or capacitance as well as the formulas for calculating ground currents for complete ground faults. (Depending on the location, the allowable ground fault current may be restricted. In this case, use values of R and C that do not exceed the restrictions.)
