SZJ300A Normally Open DC Contactor

A defining characteristic of a normally open DC contactor is its design. In the default state, the contacts remain open, blocking the flow of current. This design ensures that power is supplied to the circuit only when the contactor is energized. This feature is particularly useful in applications where safety and energy efficiency are critical, as it minimizes the risk of accidental circuit closure and energy waste. The normally open configuration is ideal for applications that require the device to remain closed until explicitly activated.

This product have one normally open contact, for electric vehicles, telecommunication equipment, engineering machinery, car batteries, electric forklift trucks, trains, ships, electronic control systems such as uninterruptible power supply.

 

 

When ordering, please state the following: name, full model, control coil voltage specification, installation frame type, whether with auxiliary contact, order quantity. For example: DC Contactor SZJ300A/24V 100pcs, indicating the load rated current 300A, without auxiliary contact, default mounting bracket, coil control voltage 24V purchase 100pcs. Special voltage specification products, such as user needs can be special order.
