This heavy-duty relay is designed to handle the demands of various control systems, providing precise and reliable switching functions. Each pole features a silver-contact design, ensuring optimal conductivity and long-lasting performance. The contacts are also gold-plated, enhancing their resistance to corrosion and oxidation, making this relay an excellent choice for applications in humid or harsh environments.

The BFF84F is a compact and space-saving design, making it easy to integrate into existing control panels or new installations. The relay measures 5.0 inches (127 mm) long, 2.7 inches (68.6 mm) wide, and 1.6 inches (40.6 mm) high, allowing it to fit seamlessly into most control systems.

The relay is housed in a robust die-cast aluminum enclosure, providing excellent heat dissipation and protection against external impacts. The enclosure is also designed to meet NEMA 1, 2, 3, 4, 12, and 13 specifications, ensuring its suitability for various indoor and outdoor installations.

The Dwyer BFF84F Cutler-Hammer BFF Control Relay features a clear and easy-to-read front panel, displaying the status of each pole through an indicator light. The relay also comes with a built-in coil, eliminating the need for an external coil, simplifying installation and reducing overall system complexity.

This relay offers excellent electrical performance, with a contact bounce time of less than 10 microseconds and a contact resistance of less than 5 ohms. It also has a current inrush capacity of 10 times the rated current for each pole, ensuring reliable performance even during heavy load switching.

The BFF84F is also UL recognized and RoHS compliant, ensuring its adherence to the highest safety and environmental standards. This relay is an excellent choice for any application requiring precise and reliable control of multiple AC circuits, offering excellent performance, durability, and ease of installation.

Pros and Cons of Buying Dwyer BFF84F Cutler-Hammer BFF Control Relay (300V AC, 10 Poles, NC, 10 Amp Poles)

a. High Voltage Capability: This relay can handle a voltage of 300 volts AC, making it suitable for industrial applications where higher voltage levels are common.

b. Large Number of Poles: With ten poles, this relay can control multiple circuits or devices in parallel, reducing the need for multiple relays and simplifying wiring.

c. Normally Closed Contacts: The normally closed (NC) contacts ensure that the circuit is closed when the relay is de-energized, providing additional safety and reducing the risk of accidental operation.

d. High Current Handling Capability: Each pole can handle a maximum current of 10 amps, allowing it to handle a reasonable load without overheating or failing.

a. Complex Wiring: With multiple poles, the wiring can become complex, requiring additional time and effort to properly connect the relay to the circuit.

b. Size and Weight: Due to its larger number of poles and higher voltage handling capacity, this relay is larger and heavier than single-pole relays, which can make it more difficult to install in confined spaces.

c. Cost: The higher number of poles and voltage handling capacity make this relay more expensive than single-pole relays, which may be a consideration for some buyers.

The Dwyer BFF84F Cutler-Hammer BFF Control Relay (300V AC, 10 Poles, NC, 10 Amp Poles) offers several advantages for industrial applications, including high voltage handling capacity, a large number of poles, and normally closed contacts. However, it also comes with some disadvantages, such as complex wiring, larger size and weight, and a higher cost compared to single-pole relays.

If you require the ability to control multiple circuits or devices in parallel and can accommodate the larger size and weight, as well as the higher cost, this relay may be an excellent choice for your industrial application. However, if your application only requires the control of a single circuit or device, a single-pole relay may be a more cost-effective and simpler solution.
