NC contact normally closed E-NC 004771501

Normally closed contact – a reliable element in the control circuit

This normally closed (NC) contact, designated as E-NC and catalog number 004771501, is a key component in control and signaling systems. Its screw connection-based construction ensures a solid and reliable electrical connection, and its operation is based on interrupting the circuit when activated. This is an ideal solution for installers and users looking for a reliable element to maintain contactors, control them, or transmit information about the circuit status.

Functionality and application

The NC contact is factory set to the closed position – meaning the circuit is normally closed. When an external force is applied (e.g., by a button or contactor), the contact breaks, interrupting the circuit. This makes it suitable for many applications where it is important to monitor the status of a device or initiate an action when a button is pressed. For example, it can be used in alarm systems, industrial automation, or lighting control.

Characteristics and operating parameters

The rated operating current for AC-15 at 230 V is 1.5 A, making it suitable for circuits with medium power consumption. It has one normally open contact, which allows for additional expansion of the control system functionality. The device was designed by ETI POLAM SP. Z O.O., a Polish manufacturer of modular equipment known for the high quality and reliability of its products. Thanks to this, you can count on stable operation and long life of this component in your installation.
