5BXX STRUTHERS-DUNN Dunco Latching Vac Coils Dpst

Review STRUTHERS-DUNN 5bx Dunco Latching Vac Coils Dpst 30 Amps 115

The Struthers-Dunn 5BXX Dunco Latching Relay is a versatile and reliable electromechanical switching device designed for applications requiring single-pole double-throw (SPDT) switching action with 115 volts AC coils and vacuum contacts. This heavy-duty relay boasts a number of impressive features, making it an excellent choice for various industrial automation and control systems.

The latching mechanism of this relay ensures that the contacts remain in their last closed position until an external force is applied to change their state. This feature is particularly useful in applications where it is necessary to maintain a specific contact configuration for extended periods. It also eliminates the need for constant power to hold the contacts in place, thereby reducing power consumption.

This 30-amp, 115-volt AC coils relay features vacuum contacts with a contact rating of 10 amps at 125 volts AC. Vacuum contacts offer several advantages over other types of contacts, such as a longer lifespan, lower contact resistance, and improved reliability in harsh environments. They are also self-cleaning, as the vacuum effect draws in any contaminants, keeping the contacts clean and free from debris.

The compact size of the Struthers-Dunn 5BXX Dunco Latching Relay makes it ideal for space-constrained installations. Its rugged construction, including a die-cast aluminum housing and gold-plated contacts, ensures that it can withstand the rigors of industrial applications. Additionally, it comes with a built-in coil overvoltage protection feature, which guards against potential damage caused by voltage surges.

Installation of the Struthers-Dunn 5BXX Dunco Latching Relay is straightforward, thanks to its clear markings and user-friendly design. It is also RoHS compliant, making it an eco-friendly choice for those concerned about the environmental impact of their purchases.

In summary, the Struthers-Dunn 5BXX Dunco Latching Relay is a robust, reliable, and efficient electromechanical switching solution for industrial applications requiring SPDT switching action with 115 volts AC coils and vacuum contacts. Its latching mechanism, compact size, rugged construction, and self-cleaning vacuum contacts make it an excellent choice for various automation and control systems.

Details:

There are two coils, both operate on 115 vac, 60 Hz. The coils draw around 10 watts when energized, I don't believe continuous operation of the is recommended. This appears to be nos, but does not come with factory packaging. This relay works perfectly, and shows only minor storage wear no corrosion.

If the second coil is pulsed, contacts open. The contacts show no pitting or other evidence of use. The contacts are dpst 2 independent form. Offered is this 76, Struthers-dunn dunco latching relay.

If the first coil is pulsed, contacts close.
