CEZC100-250 SHT UVR UVRN
Inquire NowDescription
The CEZC100-250 SHT UVR UVRN is a state-of-the-art circuit breaker release designed for enhanced safety and reliability in various applications. With over 30 years of expertise in producing high-quality products at moderate prices, this device is an ideal solution for dealers, wholesalers, and clients seeking dependable equipment. It features two primary functions: Shunt Trip (SHT) and Under Voltage Release (UVR/UVRN), ensuring optimal protection against electrical faults.
Shunt Trip (SHT): This functionality allows the circuit breaker to trip when the control voltage exceeds 0.7 times the rated voltage (Un). Control signals can be either impulse type (20 ms) or maintained, providing flexibility based on operational requirements.
Under Voltage Release (UVR/UVRN): This release mechanism trips the circuit breaker when the control voltage falls below a specified threshold, which ranges from 0.35 to 0.7 times the rated voltage. Additionally, the circuit breaker can only be closed if the voltage exceeds 0.85 times the rated voltage, ensuring safe operations.
The CEZC100-250 is designed for ease of operation, requiring local resetting after a trip caused by either SHT or UVR/UVRN. Notably, SHT or UVR/UVRN tripping takes precedence over manual closing, preventing any accidental reconnection when a trip order is active.
Compliant with standard IEC 60947-2, this circuit breaker release guarantees safety and functionality in diverse electrical systems.
