1SFA664004R1250 ABB TVOC-2-OP25 Optical Cable 25 m

Why Choose the ABB TVOC-2-OP25 Optical Cable?

The ABB TVOC-2-OP25, order code 1SFA664004R1250, is a genuine 25 m fibre-optic interconnection cable designed for the ABB Arc Guard System TVOC-2 and CSU-2. It provides optical signal transmission between compatible Arc Guard components, supporting flexible system layouts across larger switchgear assemblies.

The TVOC-2-OP25 can be used to connect TVOC-2 to TVOC-2, TVOC-2 to CSU-2, or CSU-2 to CSU-2. When installed between TVOC-2 Arc Monitors, the optical connection can be used to transfer the current sensing unit signal between Arc Guard devices, allowing current information to be shared as part of a coordinated arc-flash protection system.

With a generous 25 m cable length, the TVOC-2-OP25 is particularly useful where Arc Guard components are distributed across larger switchboards or multiple switchgear sections. The fibre-optic design transmits signals using light and provides a purpose-designed connection for compatible ABB TVOC-2 and CSU-2 equipment.

Reliable Optical Communication for Arc Guard Systems

ABB Arc Guard systems use optical signalling between compatible components to support rapid and coordinated arc-flash protection. The TVOC-2-OP25 provides the physical fibre-optic connection required to transfer signals between TVOC-2 Arc Monitors and CSU-2 Current Sensing Units without relying on a conventional conductive signal cable.

The 25 m length is particularly useful for larger electrical installations where protection components may be distributed across separate switchgear sections. It can connect two TVOC-2 units for CSU signal transfer, connect a CSU-2 directly to a TVOC-2, or interconnect compatible CSU-2 units, providing flexibility when configuring an ABB Arc Guard protection system.

Typical Applications

• ABB TVOC-2 Arc Guard protection systems.
• TVOC-2 to TVOC-2 optical interconnection.
• TVOC-2 to CSU-2 optical interconnection.
• CSU-2 to CSU-2 optical interconnection.
• Low-voltage and medium-voltage switchgear protection systems.
• Motor control centres and industrial electrical distribution installations.
