The Blue Jay arc flash relay and Littelfuse arc flash relay are both devices used for arc flash protection, but they have several key differences. This article will focus on the difference between the AFR-M arc flash relay and the Littelfuse pgr 8800 arc flash relay. You will know the difference in appearance, characteristics, sensors, voltage, and certifications.

Blue Jay Arc Flash Relay and Littelfuse Arc Flash Relay Difference in Appearance

As you can see from the above figure, the Littelfuse arc flash relay is rectangular but the Blue Jay arc flash relay is square. Dimensions of the Littelfuse arc flash relay are H 130 mm (5.1”); W 200 mm (7.9”); D 54 mm (2.1”). Dimensions of the Blue Jay arc flash relay are H 175.5 mm; W 259.1 mm; D 222 mm. The Blue Jay arc flash detection relay is with a display screen but the Littelfuse arc flash relay is not. The presence or absence of a display screen on an Arc Flash Relay can affect the way it is monitored and configured. For example, an Arc Flash Relay with a display screen can be configured and monitored directly on-site, while an Arc Flash Relay without a display screen may require an interface or other device for configuration and monitoring. The appearance of the arc flash detection relay is different because both manufacturers may have different design philosophies and technologies incorporated into arc flash relays.

Blue Jay Arc Flash Relay and Littelfuse Arc Flash Relay Difference in characteristics

Blue Jay and Littelfuse Arc Flash Relay are safety devices for electrical equipment, with the following characteristics and advantages:

Blue Jay arc flash protection relay: A reliable bird arc detector that can quickly detect arc accidents in electrical equipment and quickly cut off the circuit to protect the equipment. The device is easy to operate, easy to install, and suitable for various electrical equipment.

Littelfuse Arc Flash Relay: Based on current, voltage, time, and other parameters, the Littelfuse pgr 8800 arc flash relay can accurately control arc accidents in electrical equipment and protect the safety of equipment and personnel. The device has high accuracy and reliability and can be applied to different application scenarios and electrical equipment, supporting both on-site and remote monitoring.

Blue Jay Arc Flash Relay and Littelfuse Arc Flash Relay Difference in sensors

The Blue Jay Arc Flash Relay uses light sensors to detect arc flash events, while the Littelfuse Arc Flash Relay uses current sensors. This means that the Blue Jay may be better suited for detecting low-energy arc flashes, while the Littelfuse pgr 8800 arc flash relay may be better suited for higher-energy events. The Blue Jay Arc Flash Relay also has the option for a fiber optic sensor, which can detect arc flashes in hard-to-reach places. Moreover, both Blue Jay and Littelfuse arc flash relays can use light sensors.

Blue Jay Arc Flash Relay and Littelfuse Arc Flash Relay Difference in Voltage

Both Blue Jay arc flash relay and Littelfuse arc flash relay can be used in low and medium-voltage power systems. The Blue Jay arc Flash Relay has a maximum operating voltage of 600V, while the Littelfuse arc flash relay can handle up to 15kV. This means that the Littelfuse arc flash relay may be better suited for larger electrical systems with higher voltages.

Blue Jay Arc Flash Relay and Littelfuse Arc Flash Relay Difference in Certifications

Blue Jay Arc Flash Relay has passed IEC certification. Littelfuse Arc Flash Relay has passed UL and CE certifications.

In conclusion, this article briefly introduces the difference between the Blue Jay arc flash relay and the Littelfuse arc flash relay. If you want to know more about the difference, please contact us.
