This Acti9 MN electrical auxiliary for C60, C10, DPN, Vigi, ID, C60H-DC, SW60-DC, C60PV-DC, C60NA-DC, C120NA-DC is an instantaneous undervoltage release. It trips the device with which it is combined when its input voltage decreases (between 70% and 35% of Un). Emergency stoppage by normally open pushbutton. It ensures the safety of power supply circuits for several machines by preventing uncontrolled restarting. The width in 9mm pitches is 2. It prevents device closing again until its input voltage has been restored. The Ue rated operational voltage is 220VAC to 240VAC. The operating frequency is 50Hz or 60Hz. The operating temperature is -25°C to + 50°C. The storage temperature is -40°C to + 85°C. This product complies with IEC/EN 60947-1 and EN 60947-2 standards.
