ST40-31 – 40 A contactor with a 3NO+1NC configuration
The ST40-31 has three normally open contacts and one normally closed contact. Applying voltage to the coil causes all four circuits to change state simultaneously.
The 3NO+1NC configuration allows the contactor to be used in more complex control systems.
