There is no denying that the 7689-5 terminal is a commonly used and reliable device, having been around for over 25 years. This article will attempt to explain its applications and the principles of its operation.

The 7689-5 is a screw connector terminal that is available in both Male and Female configurations. It is IEC rated as IP50, and is usually made of an aluminum, brass or bronze alloy. It is available with several different cable sizes depending on the application and is rated for up to 95 amp loads. This terminal is typically used for the connection of electrical circuits such as lighting, heating, and in some cases, motor operation.

In terms of operation, the 7689-5 is a relatively simple device – essentially two electrical conductors which are in contact with each other. The conductor on the female side is connected to the cable via one or more machine screws, while the conductor on the male side is connected to the matching male terminal via the same type of screws.

The connection is made through the friction created between the two conductors, as they become pressed against each other when the screws are tightened. This friction produces an electrical connection, meaning that current can be passed between the two conductors. It is worth noting that while friction connections are usually good enough for low power applications, the 7689-5 is rated for higher loads and will remain reliable even under such conditions.

In terms of its applications, the 7689-5 is generally used in a range of industrial control applications. The device is commonly used for the disconnection of motors, while its resistance to higher current loads has also made it a popular choice for multiple lighting circuits or the connection of several outlets.

More specifically, the 7689-5 is often used in the connection of switchgear with control circuits, and also for the connections of contactors (aka relays). Finally, the terminal can also be used for heating or air conditioning circuits. As such, the 7689-5 is a versatile device which can be used in a range of industrial environments.

In conclusion, the 7689-5 terminal is a reliable and adaptable connector with a proven track-record of use in a range of applications. As such, it is likely to remain a valuable asset to engineers and technicians for the foreseeable future.
