GE WKA-15 Relay Coils

The GE WKA-15, also cataloged as the WKA-15 Relay Coil, operates as a dedicated hardware component for electromagnetic coil actuation within GE control and protection networks.

Hardware Specifications

Backplane Bus Communication Velocity Licences

Backplane bus communication velocity Licences and deterministic controller timing govern peripheral relay coil actuation across power protection architectures. High-density I/O density scaling coupled with validated firmware flash compatibility prevents signal processing delays between field sensors and tripping circuits. Proper channel-to-channel isolation limits ground loop currents, maintaining operational integrity during switching transients.

Frequently Asked Questions

Q: What are the physical dimension constraints when installing the WKA-15 coil into a relay socket assembly?

A: The coil measures 2.4 inches in length (without socket) and 2.1 inches in width, featuring a 0.35 inch bore for internal core engagement. Ensure physical clearance within the panel frame before mounting.

Q: Is hot-swapping permitted for the WKA-15 relay coil while energized?

A: No. Disconnect the main excitation supply prior to removal or insertion to prevent contact electrical arcing and induced transients across adjacent control circuits.

Field Installation Guidelines

• Isolate all control circuit voltage sources feeding the relay panel before inserting the WKA-15 unit.
• Inspect the 0.35 inch bore and frame surface for dust or physical obstructions prior to seating.
• Ensure proper chassis grounding across the enclosure panel to mitigate high-frequency electrical noise during coil switching.
• Torque terminal connections to standard panel specifications to maintain low-resistance lead contact.
• Route excitation power wiring away from sensitive low-voltage signal cabling to reduce electromagnetic coupling.
