TKDGQ series self-restoring over/under voltage protector
Product Details
Scope of application
The TKDGQ series self-restoring over-and-under voltage protector is a protective device developed based on the current mains power conditions. When the voltage is higher or lower than the operating voltage of the protector, the protector can quickly and reliably cut off the load power to ensure the safety of electrical appliances and personnel. When the mains voltage returns to normal, the protector automatically connects the power supply after a delay, effectively protecting electrical appliances from the impact of instantaneous power supply, and all functions are fully automatic without manual operation.

Note: When ordering the corresponding accessories, please specify the specific product model.
Example: TKDB1-63/2P/C63+OF
MX+OF shunt release
After receiving the signal, it triggers the release of the assembled Circuit-breaker
Indicates the on/off status of the Circuit-breaker
Ensure the circuit breaker reliably trips when the power supply voltage is between 70% and 110% of the rated control power supply voltage.
Trip power consumption:
| Voltage (AC or DC) | Power Consumption | Width (mm) |
|---|---|---|
| AC 230V/400V | 40VA | 18 |
| DC 24V/48V | 45W |
The MX+OF shunt release is for short-time duty, and the coil energization time ≤1 second.
Note: When ordering corresponding accessories, please specify the specific product model.
Example: TKDB1-63/2P/C63+(MX+OF)
