Why Choose the Carlo Gavazzi PAC01CM24 Star-Delta Timer Relay?
The Carlo Gavazzi PAC01CM24 is a reliable and versatile star-delta timer relay designed for controlled starting of three-phase motors in industrial automation and electrical control systems. As part of the Carlo Gavazzi PAC01 timer series, it provides accurate star-to-delta transition timing to reduce motor starting current and improve motor protection during acceleration.
The PAC01CM24 automatically manages the transition sequence between star and delta motor connections. When the supply is applied, the relay switches the motor into star configuration for the selected period, then introduces an adjustable transition delay before switching to delta operation. This makes it suitable for motor control applications where smooth starting and reduced electrical stress are required.
With selectable star timing ranges from 0.1 s to 600 s, a universal 24–240 V AC/DC supply and an 8 A SPDT relay output with neutral centre position, the PAC01CM24 provides flexible integration into industrial motor control panels. Its compact 36 mm plug-in Euronorm housing allows straightforward installation in automation systems.

Reliable Motor Starting Control for Industrial Applications
Star-delta timer relays such as the Carlo Gavazzi PAC01CM24 are used to control reduced-voltage starting systems for three-phase motors. By initially connecting the motor windings in star configuration, the starting current is reduced before the relay transitions the motor into delta operation for normal running.
The PAC01CM24 combines accurate timing adjustment, universal voltage operation and reliable relay switching in a compact industrial format. This makes it suitable for OEM machinery, pumps, fans, compressors and other motor-driven equipment requiring controlled acceleration.
Typical Applications
- Three-phase motor starting systems.
- Pumps and compressor control panels.
- Fans and ventilation equipment.
- Industrial machinery automation.
- Motor control centres and electrical panels.
- OEM manufacturing equipment.
