800NHG4B-690
800NHG4B-690 Circuit Breaker is a G4B Molded Case Breaker designed for 690V low-voltage systems, featuring 800A current rating, 4-pole configuration, compact design, and robust fault protection. Complies with international standards, ideal for industrial power distribution and equipment safety. Ensures reliable overload/short-circuit interruption.

Product Description

The 800NHG4B-690 Circuit Breaker is a G4B Molded Case Breaker designed for 690V Low Voltage applications, supporting 3-pole configurations with a rated operational voltage of up to 690V. It integrates directly with modular accessories like shunt trips and auxiliary contacts, featuring a compact design for industrial panels. This breaker operates within a voltage range of 400-690V AC and a temperature range of -25°C to +60°C, suitable for manufacturing, energy, and heavy machinery sectors. It offers high breaking capacity and thermal-magnetic tripping for reliable overcurrent protection. While lacking built-in communication interfaces, it excels in ruggedness and durability. Key limitations include no integrated battery backup or display, and typical installation requires auxiliary modules for advanced control. Its compact size (standard DIN rail compatibility) and 50kA short-circuit rating make it ideal for high-demand environments.
