Main circuit breaker 40A E 25kA 3x1P - Selective mains circuit breaker 3-p 40A S751/3DR-E40

Main circuit breaker 40A E 25kA 3x1P - Selective mains circuit breaker 3-p 40A S751/3DR-E40 – ABB – 2CDH781001R2402 – 4016779838863: Main circuit breaker 40A E 25kA 3x1P S751/3DR-E40 Tripping characteristic E, number of poles 3, rated current 40A, rated voltage 400V, rated insulation voltage Ui 690V, rated breaking capacity 25kA, frequency 50Hz, overvoltage category 4, degree of pollution 3, rated impulse withstand voltage 6kV, size (according to DIN 43880) 6, mounting type DIN rail, degree of protection (IP) IP40, the selective main circuit breakers of the S750DR series are certified according to DIN VDE 0641-21 as voltage-independent selective main circuit breakers (SHU) and can be operated by laypersons and are designed for the highest overvoltage category. Their area of application is diverse: as a disconnecting device at the meter station in accordance with the TAB of the network operators or VDE-AR-N 4101 as well as in all low-voltage main distribution boards to protect distribution circuits and as an isolating device with a disconnecting function. The special selectivity properties to ensure high system availability should be emphasized. They are intended for mounting on a 35 mm hat profile rail according to DIN EN 60715. Devices of the S 750DR family include an integrated blocking option that enables the 3 poles of a three-phase supply to be blocked at the same time. The integrated locking slide locks in the ON or OFF position and can also be secured with a padlock, wire seal or cable tie. The switching status can be monitored via an attachable auxiliary switch.
