This electrical auxiliary is an undervoltage release (MN) for new GoPact MCCB 125. GoPact MCCB has a good price-performance ratio for basic applications and delivers a reliable electrical protection for your applications. The rated operational voltage Un is 208/240VAC 50/60Hz. The MN release opens the circuit breaker when its supply voltage drops to a value below 35 % of its rated operational voltage Un. If the supply voltage is between 0.35 and 0.7xUn, opening is possible, but not guaranteed, above 0.7xUn, opening does not take place. Circuit breaker closing is ensured when the voltage supply to the release is above 0.85xUn, below this threshold, closing is not ensured. The maximum response time is 22.8ms. The power consumption is 3VA at 208/240VAC 50/60Hz. GoPact MCCB 125 is IEC 60947-1 and IEC 60947-2 certified. GoPact MCCB range benefits from Schneider Electric quality assurance.
