Audited Supplier
Introduce:
Main Features:
1. The cabinet structure adopts an assembled type,and the circuit breakeer adopts a handcart floor standing structure.
2. Equipped with a brand new composite insulation vacuum circuit breaker,and featuring good interchangeablity,and easy replacement.
3. The handcart frame is equipped with a screw nut propulsion mechanism,which can easily move the handcart amd prevent damage to the propulsion structure due to misoperation.
4.All operations can be performed with the cabinet door closed.
5. The interlocking between the switch, handcart, and switch cabinet door adopts a mandodary mechanicallocking method to meet the "five prevention" function .
6. The cable room has amplespace and can connect multiple cables.
7.Quick grounding switch is used for grounding and closing short-circuit circuits.
8.The protection level of the shell is IP3X, and when the handcart door is open,the protection level is IP2X.
9.The product complies with GB3906-2006,DL/T404-2007,and adopts the international IEC298 standard as reference.
