Why Choose the ABB 1SDA074547R1 PR330/D-M Communication Module?
The ABB 1SDA074547R1 is a PR330/D-M communication module designed to add digital communication capabilities to compatible ABB SACE Tmax circuit breakers equipped with PR332/P or PR333/P electronic trip units. Using the industry-standard Modbus RTU protocol, the module enables compatible protection, measurement, alarm, status and maintenance information to be integrated into supervisory and automation systems.
The PR330/D-M provides an RS-485 Modbus RTU communication interface, allowing compatible circuit-breaker information to be exchanged with building management, industrial automation, energy-management and supervisory control systems. Depending on the breaker configuration and installed accessories, operating status such as open, closed and tripped conditions can be communicated remotely alongside data available from the electronic protection unit.
Designed for compatible ABB SACE Tmax T7, T7M and T8 equipment and the SACE X1 platform, the 1SDA074547R1 provides a coordinated ABB solution for integrating intelligent circuit breakers into connected low-voltage distribution systems. It is particularly valuable where centralised monitoring, diagnostics and improved visibility of electrical distribution equipment are required.

Modbus RTU Connectivity for Intelligent Power Distribution
Modbus RTU provides a widely used serial communications method for integrating electrical equipment into industrial automation and supervisory systems. With the PR330/D-M installed in a compatible ABB configuration, information available from the circuit breaker and electronic protection unit can be communicated over the network, giving operators improved visibility of distribution-system conditions from a central location.
For installations requiring additional remote functionality, the PR330/D-M can form part of a broader ABB architecture incorporating compatible measurement and actuation accessories. This makes the module suitable for connected switchboards where circuit-breaker supervision, energy information and remote management are important elements of the electrical distribution strategy.
