Product Description

 

Zhejiang Xingyuan Electrical Appliances Co., Ltd

 

The LTWl series intelligent universal circuit breaker is designed for AC 50Hz systems with a rated working voltage up to 690V and a rated working current up to 6300A. This circuit breaker is ideal for distribution networks, providing protection against overload, undervoltage, short circuit, single-phase grounding, and other faults.

 

Featuring intelligent protection functions, the circuit breaker offers accurate selective protection to enhance power supply reliability and prevent unnecessary power outages. It also comes equipped with an open communication interface, enabling "four remote" operations to meet control center and automation system requirements.

 

With a pulse voltage of 8000V at altitudes up to 2000 meters (adjusted according to standard correction for different altitudes, not exceeding 12000V), this circuit breaker ensures reliable performance even in challenging environments. Additionally, the circuit breaker can function as an isolator when used without an intelligent controller and sensor.
