        • PRODUCT OVERVIEW

          What is this product?

          The WKA-15 is a differential (current transformer) component used in industrial earth leakage detection systems , designed for networks where the neutral is directly connected to earth. It operates as part of an insulation monitoring and protection system in combination with RDH, RDHT, and RDHA earth leakage relays. In this configuration, the WKA-15 functions as a measuring transformer that detects residual or leakage currents in the power network and transmits this information to the protection relay for evaluation. In practical operation, the WKA-15 is used together with RDH-series relays, which trigger a trip signal when the detected leakage current exceeds an adjustable threshold. Depending on the relay type (RDH, RDHT, or RDHA), the system may include latching or self-resetting behavior, as well as adjustable time-delay functions for selective tripping coordination. The WKA-15 transformer itself is typically paired with RDH-type devices that do not include a test function, while WKAT variants are used when test windings are required. From a system integration perspective, the WKA-15 is part of a safety-oriented leakage protection architecture used in industrial electrical installations. It is installed in conjunction with protection relays mounted in electrical cubicles, where it contributes to fault detection and system isolation in case of ground leakage. The overall system is designed for harsh industrial environments, with the associated relays supporting operation across wide temperature ranges, high humidity conditions, and flexible mounting positions, ensuring reliable operation in electrical distribution and industrial automation networks.

      • How is the exact WKA-15 execution confirmed?

        Read the complete WKA-15 marking and compare its revision, connectors and receiving position with the approved equipment record.

      • Which platform must WKA-15 match?

        The supplied a differential (current transformer) component must match the documented GE Industrial Controls hardware and project configuration.

      • Which function does WKA-15 perform?

        Use WKA-15 only for its documented a differential (current transformer) component function; do not transfer a role from a visually similar board or module.

      • Which voltage tolerance applies to WKA-15?

        The retained product record states Voltage tolerance: ±10% typical industrial design range; confirm the supplied execution carries the same value.
