Auto power relay CMA3-1(ZETTLER AZ979/980) SPDT 80A, 29*29*26.5mm
Description:
A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid-state relays. Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal.
Single Pole Double Throw (SPDT):
Such relay consists of a pair of coil pins, a common pin, a normally open (NO) pin and a normally closed (NC) pin. When the relay is not activated, the common pin is in contact with the NC pin and when it is activated, the common pin will break away from contact with the NC pin and subsequently makes contact with the NO pin. Also, when the relay is deactivated (from activated state), the common pin will conversely break away from contact with the NO pin and return back in contact with the NC pin.
Features:
• Low coil power consumption
• High sensitivity.
• Small size, light weight.
• PC board mounting.
Applications:
Relays are used in electronics to switch a smaller current which in turn will control larger current. They prevent the user to have direct contact to the main device being controlled that might be holding high voltage. These devices are comparable to a remote c ontrol which is used to make a big electronic equipment work.

CAUTION:
1.The use of any coil voltage less than the rated coil voltage will compromise the operation of the relay.
2.Pickup and release voltage are for test purposes only and are not to be used as design criteria.
3.Unless otherwise stated, the rated coil voltage specified in coil parameter tableshall be used for all tests and its application to the relay
