The SEL-300G relay protection device provides proven primary and backup protection for utility and industrial generators according to IEEE turbine protection standards. Key features of the SEL-300G generator relay include: Complete generator protection – Connecting the SEL-300G generator relay to large generators provides complete primary and backup protection.
Adding a neutral voltage connection based on third harmonic voltage measurements provides 100% stator grounding protection. Connecting a neutral current input provides protection for machines with direct grounding or resistive grounding. Secure remote control and monitoring – Control, monitor, and alarm using Modbus and ASCII communication functions.
Control relay operation and initiate or stop automation sequences from remote or local control systems. Differential Current Protection – Utilizes a sensitive percentage-constrained current differential element and an unconstrained element, along with synchronization checks and volt/hertz elements, to protect generators and step-up transformers.
The SEL-300G includes phase shift and amplitude difference compensation for current differential applications, including generators and step-up transformers. Overexcitation Detection – Detects overexcitation using volt/hertz elements in generators and step-up transformers. Choose from multiple curves and definite-time elements for alarm and trip applications.
Our company is a leading supplier of SEL-300G generator relay protection devices from the USA, sourced directly from the manufacturer to ensure authenticity.
The SEL-300G relay protection device is summarized below: Comprehensive Generator Protection: Numerous current, voltage, frequency, and distance elements provide comprehensive protection for both large and small machines.
Stator Ground Fault Protection: Stator ground fault protection uses fundamental frequency overvoltage and third harmonic voltage differential elements to protect generators with high impedance grounding. Differential Current Protection: Optional current differential elements optimize protection for large while remaining economical for small machines.
Phase shift and amplitude difference compensation for current differential applications, including generator step-up transformers. curves and definite-time elements for alarm and trip applications. Sensitive directional power elements prevent reverse power, overload conditions, or low forward power.
RTD-based protection with optional thermal protection elements works with the SEL-2600A RTD module. Metering and reporting: Event reporting, Sequential Event Recorder (SER) reporting, and high-precision metering eliminate or reduce external metering requirements.
acSELerator QuickSet SEL-5030 software allows you to develop relay settings, program SELogic control equations, and analyze post-fault event reports offline, accelerating relay applications. Secure remote control and monitoring are provided using Modbus, ASCII, and SEL Fast SER functions for control, monitoring, and alarming.

Plain language sourcing guide for American SEL-300G generator relay protection device
Start with the full model name. Check the brand name. Check the part number. Check the code on the old unit. These small checks help you avoid a wrong order.
Take one clear photo of the front label. Take one photo of the side label. If the part has a cable, plug, port, seal, coil, or screen, take a photo of that area too.
Tell us the quantity you need. Tell us your country. Tell us the date when the plant needs the part. We can then check stock, lead time, safe packing, and the best shipping plan.
If the exact model is no longer made, do not guess. Send the old model and the use case. LEHIY can compare close options and explain which choice is safer for repair work.
Use simple order notes. Write the model in one line. Write the quantity in one line. Write the delivery country in one line. This helps our team reply faster.
Check the old part before removal. Look at the label. Look at the connector. Look at the mounting size. Look at the voltage or pressure rating if it is shown.
Do not rely on a short nickname for a part. Many industrial items have close versions. A small suffix can change the plug, output, range, or software setting.
Ask for a stock check if the plant is stopped. Ask for a lead time if the order is planned. Ask for packing photos if the part is fragile or heavy.
For a replacement order, tell us what failed. Tell us where the part is used. Tell us if an equal model is acceptable. This makes the first answer more useful.
For repeat orders, send the last invoice, old label, or old packing photo. The same reference can help us match the correct product again.
For urgent service, keep the message simple. One model, one quantity, one photo, and one delivery target are enough for a fast first check.
