Current monitoring relays are designed to monitor, control or display the good working order of electrical loads. If the current drops below the specified value, this can be signalled as a function of the configuration of the control output, or a spare load can be activated respectively. A sample application is to de-energize the rear fog lamp of a tractor. Current monitoring relays are often used in emergency or command vehicles with electrical attachments or mounted implements, and more specifically with safety-relevant components.
