SIEMENS WLETU776 trip device
Product Manual：
SIEMENS WLETU776 Siemens circuit breaker electronic trip device, responsible for circuit fault monitoring and trip protection.
15 characteristics
1. WLETU776 is installed inside the Siemens frame circuit breaker to monitor real-time changes in circuit current.
2. Equipped with multiple types of protection such as overload, short circuit, and leakage, it can drive the circuit breaker to open in case of abnormalities.
3. The panel buttons can set protection action parameters on site and adapt to different load conditions.
4. Record the fault tripping for easy maintenance and inspection of the cause of the tripping.
5. Equipped with a communication interface, it can be connected to the backend for remote monitoring.
6. Anti electromagnetic interference design, making it less likely for equipment around the distribution room to cause false tripping.
7. Wide temperature components can work stably inside high and low temperature switchgear.
8. Integrated plug-in structure, can be directly disassembled and replaced in case of malfunction.
9. Built in overheating protection, enters the protection state when the temperature rise exceeds the standard.
10. Support three-phase imbalance monitoring and provide timely protection signals for phase loss conditions.
11. Shell insulation protection, dust-proof and moisture-proof, suitable for industrial and mining power distribution environments.
12. Match with circuit breakers of the same series, with high universality of spare parts and no need to modify wiring.
13. The setting parameters can be encrypted to avoid human tampering with the set values.
14. Real time display of operating current for easy operation and maintenance inspection of load status.
ending
The original procurement cycle is long, and WLETU776 is a key spare part for low-voltage distribution systems.
