The SEL-751A feeder protection relay, a microprocessor-based protection device from the USA, is available in the following models: 751A01G1G1G73860600, 751A01G1G3G71860300, and 751A01G3G1G71810300. We offer remote or on-site installation and commissioning services for SEL products.
We source directly from the USA SEL factory, guaranteeing authenticity, and utilize group-buying logistics for competitive pricing. We recommend choosing the SEL-751 feeder protection relay instead of the SEL-751A.
The SEL-751 supports additional protection and communication options such as fault location, high-impedance fault detection, EtherNet/IP, and integrated network servers. It also features a color touchscreen display. SEL will continue to support and provide warranty service for the SEL-751A.
The American SEL-751A microprocessor-based protection device offers comprehensive feeder protection using time- and transient overcurrent, overvoltage, undervoltage, and frequency elements to maximize control scheme flexibility and provide circuit breaker failure protection for a three-pole circuit breaker.
Optional protection functions combine the SEL-751A with one of the voltage input options to provide over- and under-frequency, rate of change of frequency, overvoltage, and undervoltage protection, as well as synchronization checks, DC station battery monitoring, arc-flash detection, and power and demand metering.
Convenient control allows for quick, personalized control using four programmable buttons on the front panel. Easy communication is achieved through Ethernet or serial communication and a variety of protocols, including Mirrored Bits communication and IEC 61850.
Multiple sessions can be selected from Modbus TCP, Modbus Serial, DNP3 LAN/WAN, or DNP3 serial to customize configurations for your application. Extended SELogic control equations combine mathematical and logical combinations of analog and digital values for customized applications. System control can be adjusted based on pre-fault conditions.
Analog values can be scaled and transient inputs latched for SCADA retrieval. Reclosing control uses a programmable quad recloser with optional synchronization checks to suit various reclosing practices.
Its rugged design ensures reliability with the industry's widest operating temperature range: –40°C to +85°C (–40°F to +185°F).
The SEL-751A withstands vibration, surges, rapid transients, and harsh temperatures, meeting stringent industry standards. The conformal coating option on the printed circuit board provides an additional barrier against airborne contaminants such as hydrogen sulfide, chlorine, salt, and moisture.
Furthermore, the SEL-751A is ATEX and Underwriters Laboratories (UL) Class I 2 certification, making it suitable for hazardous and potentially explosive environments. Our company offers the SEL-751A microprocessor-based feeder protection relay, sourced directly from the manufacturer to ensure authenticity.
In addition, the SEL-751A feeder protection relay features: Automatic notification via direct SEL-3010 event messenger support, automatically alerting key personnel to issues. Easy to install: Easily install into existing locations using available retrofit kits and mounting adapters, requiring no cutting or drilling.
Flexible design: Choose from a variety of installation and integration options, featuring a small form factor and slide-in expansion cards. For more information on the American SEL-751 microprocessor protection device, please contact our sales department.
Plain language sourcing guide for American SEL-751A microprocessor-based protection device feeder protection relay
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.
