Model and its meaning

Installation and wiring

Before installation, check whether the product markings match the conditions of use.

Connect the incoming and outgoing terminals according to the product identification, and connect the outgoing terminals correctly (the load current should not be greater than the rated current value of the product).

The N pole cannot be connected incorrectly, and the wiring must be reliable, otherwise the protector will not work properly.

For the cross-sectional area of ​​the connecting wire, refer to Table 1 for the cross-sectional area and rated current of the connecting wire.

Scope of application

OUPA-1 self-restoring over-voltage and under-voltage protector is a new type of intelligent protection appliance. This product adopts modular standard design. When over-voltage or under-voltage occurs in the power supply line, the protector can quickly and safely cut off under the continuous high-voltage impact. circuit to avoid accidents caused by abnormal voltage being sent to terminal appliances. When the voltage returns to normal, the protector will automatically connect the circuit within the specified time to ensure that the terminal appliances operate normally without being left unattended.

OUPA-1 self-restoring over- and under-voltage protector is suitable for users or loads with AC voltage 230/400V, frequency 50Hz, and rated operating current 80A and below. Mainly used in residential household boxes or other distribution lines that need protection.
