GIC Earth Leakage Relay vs Blue Jay Earth Leakage Relay
An earth leakage relay can protect humans and equipment from earth leakage faults. There are many different brands of reliable earth leakage relays on the market. This article will explore GIC and Blue Jay earth leakage relays from different perspectives to help you choose the best industrial-grade current protection relay.
GIC Earth Leakage Relay vs Blue Jay Earth Leakage Relay in Specification
Comparison Item GIC Earth Leakage Relays Blue Jay Earth Leakage Relays Leakage Current Setting Range Relatively wide, e.g., 30 mA – 30 A, offering a variety of model options. Also has a relatively wide range, e.g., 30 mA – 5 A, or 1-30 mA, 5-100 mA for specific applications (e.g., EV charging). Time Delay Setting Configurable tripping time, e.g., 0 – 10 seconds. Adjustable tripping delay, e.g., 50 ms – 10 seconds, with higher time resolution. Display Method Some high-end models feature a seven-segment digital display, showing real-time current. More models use a digital display screen, which can intuitively show real-time leakage current values, making debugging and monitoring convenient. Communication Function Some models support RS485 communication, allowing for integration into SCADA and other higher-level monitoring systems. Many models have built-in RS485 Modbus communication, which facilitates data acquisition and remote monitoring. Fault Type Detection Traditional models are mainly AC (Type AC). Some models also support Type A and Type AC. The product line is more extensive, offering not only Type AC but also Type B or AC/DC relays specifically for detecting mixed AC/DC leakage currents, which are very suitable for EV charging piles, photovoltaics, and other fields. Leakage level indication Indication of 30%, 45%, 60%, 75% of set Earth Leakage level with colour LED indication Free set the value of Leakage level indication
GIC Earth Leakage Relay vs Blue Jay Earth Leakage Relay in quality
GIC earth leakage relays feature mature design and stable manufacturing processes, and have been proven in industrial environments for a long time. Blue Jay has accumulated extensive experience in emerging applications, with specialized optimizations specifically for interference immunity and adaptability to harsh environments. Blue Jay earth leakage relays are highly reliable and generally comply with international standards such as IEC.

GIC Earth Leakage Relay vs Blue Jay Earth Leakage Relay in price
GIC earth leakage relays are priced higher, earning a premium due to their excellent brand reputation, product stability, and widespread market acceptance. They are an ideal choice for projects with ample budgets and a strong focus on brand recognition. In contrast, Blue Jay earth leakage relays are more competitively priced. Still, their high level of integration (built-in communications) and specialized support for niche applications offer a higher cost-performance ratio in specific scenarios.
GIC Earth Leakage Relay vs Blue Jay Earth Leakage Relay in installation
GIC earth leakage relays typically use knobs or DIP switches for parameter setting, offering intuitive and reliable operation. The design of the Test and Reset buttons also makes function usage clear and concise. Many Blue Jay earth leakage relays, on the other hand, use buttons and digital tube displays for parameter setting and real-time monitoring, providing greater accuracy and convenience. Furthermore, built-in communication capabilities greatly simplify remote system integration.
GIC vs Blue Jay in Brand Background and Market Positioning
GIC is a long-established Indian manufacturer of electrical controls and relays. GIC enjoys a high reputation internationally, boasting a broad product line encompassing timers, monitoring relays, thermostats, and other sectors. Its products are renowned for their industrial-grade quality, stability, and reliability, and are positioned towards performance- and reliability-focused industrial and automation applications.
Blue Jay is a Chinese technology company specializing in the research and development of electricity meters and protective relays. Blue Jay’s products are recognized for their high cost-performance and high level of functional integration, particularly in emerging sectors such as electric vehicle charging stations and photovoltaic inverters, where they offer a wide range of customized solutions. Its market position is focused on niche markets that are cost-sensitive but also seek specialized functionality.
Conclusion
While both brands offer reliable earth leakage relays, their strengths lie in different applications.
For projects that require a proven brand, industrial-grade reliability, and broad market acceptance in traditional industrial or power distribution settings, GIC is a highly dependable choice.
Conversely, for applications that require specialized features—such as in electric vehicles, photovoltaics, and DC systems—along with a cost-effective solution and integrated communication for remote monitoring, Blue Jay offers a distinct advantage.
