Dual Power Transfer Switch (PC Class / CB Class)

PC Class & CB Class Automatic / Manual Changeover Switch for Dual Power Supply

$160.00

Overview

Nelink dual power transfer switch is available in PC class and CB class types for low-voltage distribution systems. PC class adopts integral switching structure, providing strong short-time withstand current and reliable isolation, suitable for general important loads. CB class consists of two molded case circuit breakers (MCCB) with built-in overload and short-circuit protection, suitable for loads requiring both switching and protection. Both types support automatic and manual operation modes. In automatic mode, the switch continuously monitors two independent power sources and switches to standby power when main power fails. Mechanical interlock ensures only one source connected at a time. Compliant with GB and IEC standards.

Key Features
