Schrack ZR4MF025-A Relay

The relay, also known as contactor, contact switch, or electromagnetic switch, with type number ZR4MF025-A from Schrack, is an electrical switching relay from the field of electricity. It has the dimensions 10 x 10 x 10 cm and a weight of 0.145 kg. Relays are electrical switches that are actuated by a control current to open or close a load circuit. They enable the control of high currents or voltages with low control currents and provide electrical isolation between the control and load circuits. Typical applications are found in automation technology, for example, for controlling motors or lighting systems. Relays are also indispensable in building technology, for instance, for switching heating and air conditioning systems.
