Type 201

~ 80 mm
Typ 201 von E-T-A: ist ein einpoliger, thermischmagnetischer Schutzschalter mit Handauslösung für Tragschienenmontage.


Single pole thermal-magnetic circuit breaker with tease-free, trip-free, snap action mechanism and two button operation (M-type TM CBE to EN 60934). Featuring a narrow profile housing, recessed terminals, standard EN rail mounting, and precision CBE performance.

E-T-A’s 201 is a single pole, thermal-magnetic circuit breaker with manual release button for rail mounting. It is a very compact circuit breaker which is ideally suited to basic applications without auxiliary contacts. The 201 can be switched on with a black push button. The separate red manual release button serves for manually switching off. In the event of tripping due to overcurrent or short circuit as well as after manual disconnection, the breaker can be reset by means of the black push button. Resettability ensures a significantly higher system availability than conventional blade fuses.
