Connection bridges 15mm

Overview

The CB-15 Connection Bridges are professional installation accessories for the Elausys Universal KNX Actuator System, featuring a 15mm bridge size designed for actuator modules with wider terminal spacing. These bridges enable efficient power distribution by connecting the phase terminals of consecutive switching channels on the MSA-810 master actuator and its extension modules. Each pack contains 10 bridges, providing sufficient quantity for typical actuator configurations.

Technical Capabilities

The connection bridges provide a secure electrical connection between adjacent channel terminals, allowing multiple switching outputs to share a common phase supply. This eliminates the need to wire each channel individually to the power source, significantly reducing installation time and cable volume within electrical cabinets.

The 15mm bridge size accommodates actuator terminal blocks with wider spacing compared to the standard 10mm CB-10 bridges. This larger size ensures proper fitment on modules where terminal centers are spaced further apart, maintaining reliable electrical contact across the full current capacity of connected channels. The bridges ensure safe operation under load conditions typical in building automation applications.

Installation and Configuration

Installation is straightforward: insert the bridge between the phase terminals of two adjacent channels that require the same power supply. Multiple bridges can be used in sequence to connect several consecutive channels to a single power feed. The 15mm bridges snap securely into compatible actuator terminal blocks without requiring additional tools.

For optimal installation, verify terminal spacing requirements before selecting bridge size. The CB-15 is intended for modules with wider terminal configurations, while the CB-10 serves standard spacing. Group channels by circuit breaker assignment and use bridges to minimize the number of incoming phase wires. This approach results in cleaner cabinet layouts and simplified troubleshooting. Always ensure the total load on bridged channels does not exceed the upstream circuit protection rating.

Applications

Residential installations benefit from bridged configurations when multiple lighting circuits share the same phase. A typical home might use 3-4 bridges to connect living room, dining room, and hallway lighting channels to a single circuit breaker, reducing wiring from multiple individual connections to one feed wire plus bridges.

Commercial projects with larger actuator configurations gain significant time savings. Extension modules controlling office lighting across entire floors can use bridges to distribute power from circuit breakers rather than wiring numerous individual phase connections. The 15mm size ensures compatibility with wider-spaced terminal configurations found on certain extension types.

Industrial and technical installations appreciate the reduced cable volume and improved serviceability. Clean cabinet wiring with proper bridging demonstrates professional workmanship and simplifies future maintenance or modifications.

Compatibility and Integration

The CB-15 bridges are compatible with Elausys Universal KNX Actuator System switching products that feature wider terminal spacing, including the MSA-810 master actuator and SAE-810, SAE-816, SAE-2410, and HAE-805 extensions where terminal configuration requires the 15mm size. The bridges work with both 10A and 16A rated channels, though installers must respect the current rating of the smallest component in any bridged group.

For installations with standard terminal spacing, the CB-10 connection bridges provide the 10mm alternative. Both bridge types can be combined within the same installation as needed to accommodate different module configurations within a single electrical cabinet.
