Power relays are switching devices that allow current or voltage to pass through in circuits that have gone into overload without collapsing the circuit itself. Over 2 Amps, one such type of power relay is the MJN2C-IN-DC48. This particular relay, while designed to handle the higher amperage, is also equipped with a number of safety features to protect the circuit.

The application field for the MJN2C-IN-DC48 is the protection of electrical circuits against overload. This particular relay is suitable for use in circuits that carry currents of up to 48A and for voltages up to 440VAC, and can switch bi-directional current or voltage. It is suited to be used in applications that require the switching of single or three-phase circuits, as well as digital input switching.

The working principle of the MJN2C-IN-DC48 power relay is based on independent tripping mechanism, as well as instantaneous and delayed action. It also features an output that can be used to switch auxiliary contacts in order to give local or remote signalling. It also features a manual test button that allows to check the operation of the relay without opening the circuitry.

The MJN2C-IN-DC48 also has a number of safety features designed to protect circuits from overloading. For instance, it has an overtemperature protection that is triggered if the temperature around the relay exceeds a certain level. It also has an over current protection that will trigger if the current through the relay exceeds the specified limit.

Another safety feature of the MJN2C-IN-DC48 is an instantaneous over-load and under-voltage protection. This protection will cause the relay to instantly open if the current through it exceeds permissible limits or if the voltage supplied to it drops below limits.

The MJN2C-IN-DC48 consists of a main contactor and an auxiliary contactor, along with a thermistor relay to monitor the temperature around the relay. The main contactor functions as an on/off switch and is capable of switching a large amount of current. The auxiliary contactor is used to provide the signal to switch the auxiliary contacts, which can then be used for local or remote signalling.

The MJN2C-IN-DC48 power relay offers great protection for the circuits in which it is used, and its safety features ensure that circuits and the components in them do not suffer from the effects of overloading. Its simple design makes it easy to install and it is well suited for all kinds of applications that carry currents of up to 48A and voltages of up to 440VAC.
