Why Choose the Carlo Gavazzi CF30A20024 Power Relay?
The Carlo Gavazzi CF30A20024 is a sealed, high-capacity electromechanical power relay designed for reliable switching of demanding electrical loads in industrial machinery, control panels and building automation equipment. As part of the Carlo Gavazzi CF30 relay series, it combines a compact panel-mounted construction with two normally open contacts and a rated switching current of up to 30 A.
This non-latching relay uses a 24 V AC control coil to operate its DPST-NO contact arrangement. Energising the coil closes both normally open circuits simultaneously, enabling two separate loads or conductors to be controlled from a single low-voltage AC control signal.
With a maximum switching voltage of 277 V AC or 30 V DC, fully sealed construction and 6.3 mm Faston terminals, the CF30A20024 provides straightforward integration into electrical panels and industrial equipment. Its robust switching capability makes it suitable for compressors, motors, heating systems, lighting and other high-current loads.

Reliable Two-Pole Load Switching
Electromechanical power relays allow a low-voltage control circuit to switch substantially higher electrical loads while maintaining electrical separation between the coil and contact circuits. Applying the rated voltage to the coil creates a magnetic field that moves the internal armature and closes the relay contacts.
The CF30A20024 provides two normally open contact sets, allowing two circuits to be energised simultaneously from a single 24 V AC control signal. Its high contact rating, sealed housing and quick-connect terminals make it suitable for equipment manufacturers, control-panel builders and industrial maintenance applications.
Typical Applications
- Industrial control panels and machinery.
- Compressor and refrigeration control systems.
- Motor, pump and fan switching circuits.
- Heating, ventilation and air-conditioning equipment.
- Lighting and resistive load control.
