7-1419111-7 Application Field and Working Principle

7-1419111-7 is a family of mini-power relays designed for electrical circuits with current of more than 2 amperes. The relay is marked 7-1419111-7, indicating that the current rating is 2 amperes. The 7-1419111-7 is suitable for DC or AC control voltage application, especially for small appliance circuit applications.

The 7-1419111-7 is designed with a mercury wetted contact arrangement. Mercury wets contacts are generally preferred for high current applications, since they offer greater current handling capacity, much improved isolation, and greater long-term reliability. The contacts of the 7-1419111-7 are enclosed in a special enclosure, which is used to protect the contact from contamination and other corrosion.

In addition to the wetted contact arrangement, the 7-1419111-7 also comes with a special terminal design. These terminals have an extra spring which supports the contact when external pressure is applied. This ensures that the contacts remain securely connected even when high-frequency transients occur.

The working principle of the 7-1419111-7 is based on the same principles as other power relays. When a control switch is activated, a voltage is applied to the controlling relay, which will open the contacts and allow a current to flow. The relay will then return to its original state when the control switch is released. This allows the relay to be used to protect the device from overloading or short circuits, and also provides control over the supply current.

The 7-1419111-7 is an excellent choice for applications that require a high-power relay. It provides reliable performance and protection for power circuits, and its compact size and low cost makes it an attractive option for many applications.
