Thermostatic actuator Busch-Jaeger 2CKA006220A0025 — 6-channel, IP20, 0.16 A, 72×64×90 mm

Busch-Jaeger thermostatic actuator 2CKA006220A0025 is a compact 6-channel device designed to drive thermostatic valve actuators for radiators and underfloor heating systems. With IP20 protection and a rated current of 0.16 A per channel, it centralizes control of up to six actuators in a single module. Its small housing, measuring 72×64×90 mm, allows installation in control cabinets or built-in housings where space is limited. The unit is intended for use in HVAC zone management and temperature regulation setups where precise electrical actuation of valve motors is required.

Advantages

The actuator offers six independent channels, enabling centralized operation of multiple valves from one device. Low per-channel current rating reduces thermal load and suits many common valve actuators used in heating systems. The IP20 rating and compact footprint make it suitable for protected indoor installations and standard control enclosures. Its design supports straightforward wiring and integration into existing heating control systems without occupying excessive space.

Suitable for

• Centralized control of radiator valve actuators
• Actuation of underfloor heating zone valves
• Small to medium-sized residential and commercial HVAC zones
• Installation inside control cabinets or built-in housings
• Systems requiring compact multi-channel valve actuation

Key specifications

• Number of channels: 6 independent outputs
• Protection class: IP20 (suitable for indoor, protected environments)
• Rated current per channel: 0.16 A
• Dimensions (W×D×H): 72 × 64 × 90 mm
• Mounting: designed for installation in control cabinets or built-in housings

How to use

Install the actuator in a suitable indoor control cabinet or built-in housing ensuring the IP20 protection level is respected. Connect each valve actuator to an individual channel following the device wiring diagram and electrical safety standards. Ensure supply voltage and actuator load are compatible with the rated current of 0.16 A per channel. After wiring, test each channel to verify correct opening and closing of connected valve actuators and confirm integration with the heating control system or thermostat interface.

Usage recommendations

Use the actuator only in dry indoor environments where IP20 protection is adequate. Verify compatibility of valve actuators with the 0.16 A per-channel rating to prevent overload. For installations in exposed or humid locations, choose a device with a higher protection class. Regularly inspect connections and fastenings during maintenance intervals to ensure reliable operation.
