ABB DPT63-CB011 C20 4P Automatic transfer switches dual power automatic

ABB DPT63-CB011 C20 4P transfer switch controller is a device for automatic switching of dual power supplies. The following is a detailed introduction:

Basic parameters: "63" represents the frame current of 63A, "C" in "C20" usually indicates the tripping characteristics, here it is a lighting protection type, 20 indicates the rated current of 20A, and "4P" indicates four poles, which can control three-phase live wires and one neutral wire, and is suitable for three-phase four-wire circuits.

Control core and function: With a single-chip microcomputer as the control core, the hardware is simple and reliable. It has short circuit and overload protection functions, and can also realize automatic conversion and intelligent alarm functions for overvoltage, undervoltage, and phase loss, which can effectively ensure the safety of circuits and loads.

Working mode and position: Supports automatic resetting and automatic resetting working modes. There are three stable working positions, namely, common power on, backup power off; common power off, backup power on; common power off, backup power off.

Operation mode: It can automatically switch with load, and can also be manually switched by the handle in an emergency. There is an interlock between manual and automatic operation modes, and manual operation is not possible in the automatic state, which improves the safety of use.

Protection level and application environment: The protection level is IP20, which can prevent the entry of solid foreign objects larger than 12mm, and is suitable for general indoor environments. The installation site is not more than 2000m above sea level, the ambient air temperature is -25℃ to 55℃, the relative humidity is less than 95%, and the pollution level is III.

Application category: The application category is AC-33B, which is suitable for controlling related circuits such as motor loads.

Time setting function: The normal power return time (Tn), the backup power return time (Tr), and the normal or backup switching to the double split position time (Ts) can be set. Users can accurately set the power switching time according to actual needs.

Compliance with standards: Comply with relevant standards such as IEC60947-6-1:1998 (version 1.2) and GB14048.11-2002 to ensure that product quality and performance meet industry specifications.
