Deterministic Networks & Firmware Flash Compatibility
The 339-E-P5-G5-H-E-S-N-N-SN-D-N protective relay incorporates high-speed microprocessing circuitry to evaluate phase and ground currents against programmed protective curves. Onboard firmware flash compatibility ensures reliable event logging, oscillography capture, and deterministic register reporting across industrial communication networks. The drawout case construction permits rapid physical maintenance while maintaining backplane connection integrity and high I/O density scaling during protective trip execution.
Frequently Asked Questions
Q: Can the 339-E-P5-G5-H-E-S-N-N-SN-D-N unit be safely removed from its case while the system is energized?
A: The drawout construction automatically shorts the secondary CT inputs upon removal, allowing safe extraction of the relay unit without interrupting external current transformer loops.
Q: What power supply ranges does this specific relay configuration support?
A: The high-voltage control power supply input accepts nominal voltages ranging from 110 to 250 VDC or 110 to 230 VAC.
Q: How are the current inputs configured for phase and ground monitoring?
A: The relay features dedicated 5 A inputs for 3-phase current sensing along with a separate 5 A input channel assigned to zero-sequence or residual ground fault detection.
Field Installation Guidelines
- Mount the drawout outer case securely into the switchgear panel cutout using standard mounting hardware and verify earth bonding.
- Terminate the 5 A phase and ground current transformer secondary leads to the designated rear screw terminals, ensuring tight mechanical torque.
- Wire the auxiliary 110-250 VDC or 110-230 VAC power supply connections, checking lead polarity prior to energizing the control circuit.
- Connect the 10 contact inputs and 7 output relay contact circuits to external control and tripping schemes according to system schematic drawings.
- Insert the 339-E-P5-G5-H-E-S-N-N-SN-D-N relay inner unit into the case until the drawout latching mechanism locks firmly into place.
