TK821V020 ABB 2.0m Prefabricated AC 800M Battery Cable

ABB TK821V020 Prefabricated Battery Cable

The ABB TK821V020 (Part Number 3BSC950202R51) is a 2.0-meter prefabricated battery cable engineered for ABB System 800xA AC 800M control systems. It provides reliable electrical connections for battery modules within industrial automation enclosures, maintaining power continuity and signal integrity for system memory backup.

Physical and Environmental Characteristics

Constructed with durable insulation materials and robust connectors, the cable withstands demanding operating conditions ranging from -25 deg C to +70 deg C. Its flexible design simplifies cable routing between adjacent modules inside control cabinets while offering an IP65 protection rating against dust ingress and low-pressure water streams.

Signal Integrity and Compatibility

The assembly is designed with electromagnetic interference (EMI) resistance to prevent signal distortion in high-noise industrial environments. It supports hot-swappable installation within redundant AC 800M system architectures, allowing battery maintenance or replacement without disrupting active control operations.
