Why Choose the ABB INS-TB Tap-Off Box Module?
The ABB INS-TB is a dedicated InSite Tap-Off Box module designed for data-centre busway and distributed energy-monitoring applications. It converts the ABB InSite bus connection to an RJ45-based link, allowing current sensors and other compatible monitoring components to be installed in individual tap-off boxes without requiring a complete control unit in every box.
With an ABB SCU200 installed in the main or master box, INS-TB modules can extend the monitoring architecture across multiple tap-off points. The modules support a daisy-chain arrangement and allow the SCU200 system to be extended over distances of up to 70 m, providing an efficient architecture for distributed busway monitoring.
The INS-TB is a passive device with InSite bus and proprietary 10BASE-T RJ45 connectivity, requiring no separate local power supply. Its compact single-module DIN-rail format makes it straightforward to integrate within tap-off enclosures. ABB order code 2CMA268075R1000 identifies this dedicated InSite Tap-Off Box module.
Key Advantages
- Designed specifically for data-centre busway and tap-off monitoring applications.
- Converts the ABB InSite bus to RJ45 connectivity for distributed installations.
- Allows sensors in individual tap-off boxes to operate without a dedicated SCU200 in every box.
- Supports InSite system extension over distances of up to 70 m.
- Passive operation eliminates the need for a separate local power supply.
- Compact 17.5 mm single-module DIN-rail format supports space-efficient panel integration.
Key Features
- ABB InSite Tap-Off Box module.
- Designed for data-centre busway applications.
- Supports InSite bus and RJ45 connections.
- RJ45 interface uses 10BASE-T physical connectivity with ABB's internal proprietary protocol.
- Supports distributed sensor connections across multiple tap-off boxes.
- Designed for use with an SCU200 located in the master box.
- Daisy-chain architecture with termination switch for the final INS-TB module.
- Passive device powered through the system connection.
- IP20 degree of protection.
- Mounts on a 35 mm DIN rail.
Distributed Monitoring for Data-Centre Busway Systems
Data-centre busway installations can contain numerous tap-off boxes distributed along the power-distribution route. The ABB INS-TB enables compatible sensors within these boxes to communicate back to a central InSite control architecture, reducing the need to install a separate SCU200 control unit at every monitoring point.
By converting the InSite bus connection for transmission through RJ45 cabling, INS-TB modules can be arranged in a daisy chain between the master and individual tap-off boxes. The final module includes a switch setting for terminating the chain, while the overall architecture can extend the monitoring capabilities of the master SCU200 across distances of up to 70 m.
Typical Applications
- Data-centre busway monitoring.
- Master and slave tap-off box architectures.
- Distributed branch-circuit current monitoring.
- ABB InSite energy-management systems.
- ABB SCU200 monitoring installations.
- Critical-power distribution systems.
- Busway tap-off units with current sensors.
- Commercial and industrial distributed energy monitoring.

Frequently Asked Questions
What is the ABB INS-TB used for?
The ABB INS-TB is a Tap-Off Box module for distributed InSite monitoring, designed particularly for data-centre busway applications where sensors in individual tap-off boxes need to communicate with a central control system.
Does every tap-off box require an SCU200 when using the INS-TB?
No. The INS-TB allows the SCU200 to be installed in the main or master box while compatible INS-TB modules extend sensor connectivity to individual tap-off boxes.
How far can INS-TB modules extend an InSite installation?
ABB specifies that the Tap-Off Box architecture can extend the capabilities of the SCU200 over distances of up to 70 m, subject to the applicable system and cabling requirements.
Does the ABB INS-TB require a separate power supply?
No. The INS-TB is specified as a passive device and operates through the InSite system connection rather than requiring a separate local power supply.
Can standard Ethernet equipment be connected to the INS-TB RJ45 ports?
No. Although the INS-TB uses 10BASE-T RJ45 physical connectivity, ABB specifies an internal proprietary protocol and states that third-party Ethernet equipment must not be connected to these ports.
Trusted Distributed Monitoring from ABB
ABB InSite Tap-Off Box modules provide purpose-designed connectivity for distributed busway monitoring, enabling compatible sensors across multiple tap-off points to be integrated efficiently with a central SCU200 energy-management architecture.
