Modular Contactor ST25-40-M 4NO 4W 2mod. auto./manual mounting on DIN-rail F&F EA13.001.032 Euroautomatika F&F

"ST" series Contactor Designed for switching high-power electrical circuits. The presence of a switch on the front panel allows manual control of the contactor contacts (regardless of whether supply voltage is present on the coil). Features - Manual control - Coil power supply from AC mains Application area Used for automation and control of various technological processes, including lighting, air conditioning, ventilation systems, etc. Operating principle The operating principle of the contactor depends on the position of the operating mode switch: "I" Position When there is no supply voltage on the coil, the contactor contacts are closed. Applying supply voltage to the coil automatically moves the switch to the "auto" position, and the contactor operates in automatic mode. To fix the contacts in the closed state regardless of the presence of supply voltage, the yellow locking lever must be moved to the left in the "I" position. The operating state of the contactor is signaled by a raised red flag on the front panel. "auto" Position Applying supply voltage to the contactor coil causes the contacts to close. After the supply voltage is disconnected, the contacts return to their original position. "O" Position The contactor contacts remain open regardless of the presence of supply voltage. supply voltage 230 V AC maximum load current - 25 A; contacts - 4NO;
