SZJB600A Normally Closed DC Contactor

Normally Closed DC Contactor is an electrical switching device that is specifically used to control the flow of current in a DC circuit. Unlike a normally open contactor, when the normally closed contactor is not powered, the contacts are closed and the circuit is connected; when the contactor coil is powered, the contacts open and the circuit is disconnected.

FEATURES

The operating principle of a normally closed DC contactor is relatively simple, yet very effective. In its default state, when the contactor is not energized, the contacts remain closed, allowing current to flow through the circuit. This design is particularly advantageous in applications where continuous power is required. When the contactor coil is energized, an electromagnetic force is generated, causing the contacts to open and break the circuit. This unique feature instantly interrupts the flow of current, making it an indispensable tool in safety and automation systems.
