Description
Product Description
The DEIF PPM BTB is a Bus Tie Breaker application within the DEIF Protection and Power Management (PPM) system, designed for marine power-management installations with multiple switchboard sections. The BTB function coordinates bus tie breaker operation while the overall PPM system provides generator control, supervision, protection, synchronization, and power management. DEIF documentation for PPM-3 identifies support for up to eight BTB units, with the internal system communication handled through the dedicated CAN bus. External communication can be provided through RS-485 Modbus RTU, Profibus DP, or Ethernet TCP/IP Modbus.
The BTB function is used to manage the connection and separation of busbar sections. Depending on the configured operating mode, the system can synchronize busbars before closing the tie breaker, manage connected sections as a common power-management section, and automatically trip the BTB for configured protection conditions. DEIF documentation also describes dedicated BTB events such as BTB closed, BTB opened, and BTB synchronizing.

FAQ
Q: What is DEIF PPM BTB?
A: PPM BTB refers to the Bus Tie Breaker function/application within DEIF’s Protection and Power Management system. It manages the electrical connection between busbar sections and coordinates BTB operation with the power-management system.
Q: What does the BTB controller do?
A: The BTB controller protects and controls a bus tie breaker, while the power-management system manages the associated busbar sections.
Q: Can the system synchronize busbars before closing the BTB?
A: Yes. DEIF documentation describes BTB synchronization as part of the power-management sequence before connecting busbar sections.
Q: How many BTB units can a PPM-3 system handle?
A: The PPM-3 Designer’s Handbook specifies up to eight BTB units, with BTB IDs 33–40.
Q: What communication interfaces are supported by PPM-3?
A: DEIF lists RS-485 Modbus RTU, Profibus DP, and Ethernet TCP/IP Modbus for external communication with an alarm and monitoring system.
