Disconnect Unit 600V

DISCONNECT UNIT

Complete NEC conformity, compact in a single switch cabinet

The new Disconnect Unit combines all safety measures into a single, compact enclosure. The device is ideally suited to all Sunny Central inverters with plant voltage ranging from 600 to 1000 V currently in use in North America. All switch-disconnectors are tightly concentrated in a small space for quick access in a hazardous situation. They can operate under full loads and feature the ampacity reserves required by NEC 2011. The switching handles installed on the front enable you to immediately recognize the switch position. This guarantees a secure and fast disconnection of all energy from the inverter in case of emergency or maintenance.
