Automatic differential current switch 1P+N C 10A 30mA type AC 10kA NB1L (36mm) (R) CHINT 203105

The NB1L series differential current circuit breakers are designed for use in single-phase AC networks with a voltage of up to 230 V and a frequency of 50/60 Hz with a rated current of up to 40 A for infrequent switching on and off of loads, as well as protection against overload, short circuit, electric shock from indirect touches and fires due to current leakage in electrical installations residential, public and industrial buildings. It is necessary to check the operability of the NB1L series AVDT by pressing the "Test" button at least once a month. Main Features: Rated current – from 6 A to 40 A Pole design – 1P +N (N on the left); 2P Type of instantaneous response characteristic – B, With Breaking capacity – up to 10000 A Nom. switching–off differential current – 30 mA ; 100 mA ; 300 mA Type AVDT – AC, A Device design – electromechanical Switching frequency - up to 240 cycles /hour Mechanical wear resistance – 20,000 cycles / O Electrical wear resistance – 2000 cycles / O S
