Why Choose the Carlo Gavazzi PAC01CM40 Star-Delta Timer Relay?
The Carlo Gavazzi PAC01CM40 is a reliable star-delta timer relay designed for controlled starting of three-phase motors in industrial machinery and automation systems. As part of the Carlo Gavazzi PAC01 timer series, it automatically controls the transition between star and delta motor connections, helping reduce starting current and electrical stress during motor acceleration.
The PAC01CM40 provides selectable timing ranges covering 0.1 s to 600 s, allowing the star operating period to be matched to the starting requirements of the connected motor. A short transition interval between star and delta operation helps ensure controlled contactor sequencing before the motor changes to its normal delta running configuration.
Designed specifically for 380–415 V AC supply systems, the PAC01CM40 features an 8 A SPDT relay output and a compact 36 × 80 × 94 mm Euronorm housing. Its 11-pin plug-in socket mounting format enables straightforward installation and replacement within industrial motor control panels.

Reliable Star-Delta Control for Industrial Motors
Star-delta starting is commonly used to reduce the initial current drawn by suitable three-phase induction motors. During starting, the motor windings are connected in star configuration. After the selected starting period, the timer disconnects the star circuit and subsequently enables the delta circuit so the motor can continue operating normally.
The Carlo Gavazzi PAC01CM40 automates this sequence and provides a defined transition interval between the two switching states. Its adjustable timing, 380–415 V AC supply and plug-in construction make it particularly suitable for conventional contactor-based motor starters in industrial control panels.
Typical Applications
- Three-phase star-delta motor starters.
- Industrial pumps and pumping systems.
- Fans and ventilation equipment.
- Compressors and motor-driven machinery.
- Conveyors and material handling equipment.
- Industrial motor control panels and OEM machinery.
