5-zone control terminal block SALUS CB500X 230V (model 132502)

SALUS CB500X 230V is a 5-zone control terminal block engineered for 230-volt heating and control systems. It provides centralized connection and distribution for five independent zones, enabling organized wiring of actuators, motorised valves or thermostats in residential and light-commercial HVAC installations. The device is intended to simplify zone management and facilitate reliable electrical connections for multi-zone temperature control systems.

Advantages

The terminal block supports five separate zone outputs on a single compact module, reducing wiring complexity and saving installation space. It is designed for mains 230V systems and offers clear terminal labeling for straightforward wiring and maintenance. The robust construction and standardized terminal arrangement allow compatibility with common actuators and zone control devices used in heating systems, providing a practical solution for centralized zone distribution.

Suitable for

• Multi-zone residential heating systems
• Light-commercial HVAC installations with separate heating zones
• Connections of actuators, motorised valves and zone thermostats
• Retrofit projects where centralized zone wiring is required
• Control panels and distribution enclosures for zone management

Key specifications

• Number of zone outputs: 5 independent zones
• Supply voltage: 230 V AC
• Terminal type: screw/clamp terminals for secure wiring
• Mounting: panel or DIN-rail compatible form factor (check installer compatibility)
• Use case: designed for electrical distribution to actuators, valves and thermostats

How to use

Install the CB500X in a suitable control panel or enclosure following local electrical codes and industry best practices. Connect the 230V supply to the designated input terminals, then route and secure each zone output conductor to the corresponding terminal for the actuator, motorised valve or thermostat. Ensure all connections are tightened to the recommended torque and that protective devices such as circuit breakers or fuses are present in the supply circuit. After wiring, verify correct zone operation by energizing the system and testing each actuator or valve from its control thermostat or controller.

Usage recommendations

Use the terminal block only within its rated voltage and in dry, protected enclosures. Match actuator and valve electrical characteristics to the supply and load-handling capability of the wiring and protective devices. Have installations and any modifications performed by qualified electricians or HVAC technicians and perform insulation and continuity checks before energizing.
