Application   
In order to coordinate superior and subordinate protection of low-voltage switch and optimize operation, maintenance and management, the selected molded case circuit breaker and miniature circuit breaker shall be products of the same system (the same brand), and shall be suitable for  special environments, such as humidity, vibration, and electromagnetic interference. In order to meet the adjustment and change of electric load in different stages( initial stage, short-term stage and long-term stage), it is required that the current release of molded case switch shall be adjustable on site and have a wide range of current and time regulation. The tenderer shall provide specific current and time regulation range when bidding.
