This Acti9 iMSU electrical auxiliary is an overvoltage release. It is dedicated to Acti9 iC60, iID, iID40, iDPN Vigi, iSW-NA, iC40, iCV40, iC40 XA, iCV40 XA, iCV40 XA, iC60 & iID double terminals, iC60 RCBO, iKQE RCBO. For a four-phase network, use three iMSU tripping auxiliaries. It provides a protection of equipment against overvoltage on the electrical network (neutral conductor break) and voltage monitoring between phase and neutral conductors. It switches of the power supply by opening the breaker with which it is combined, in the event that the phase/neutral voltage is exceeded. The width in 9mm pitches is 2. There is a red mechanical indicator on the front face of the product to indicate the tripped position of the associated device. The Ue rated operational voltage is 230VAC. The operating frequency is 50Hz or 60Hz. The operating temperature is -35°C to + 70°C. The storage temperature is -40°C to + 85°C. This product complies with IEC/EN 60947-5-1 standards.
