3p 400A Circuit breaker A3794B UHL3 690V withdrawable manual remote drive Contactor 1037074 Contactor (IEK group)

Switches are designed for operation in electrical installations with a voltage of up to 690 V AC at 50 and 60 Hz and up to 440 V DC for infrequent (up to 6 times per day) operational switching of electrical circuits, as well as for protecting electrical equipment from overloads and short circuits, and also during voltage drops to an unacceptable level. A3791B — 2-pole AC or DC, current-limiting (application category A) with an electromagnetic maximum current trip unit. A3792B — 3-pole AC, current-limiting (application category A) with an electromagnetic maximum current trip unit. A3793B — 2-pole AC or DC, current-limiting (application category A) with electronic and electromagnetic maximum current trip units. A3794B — 3-pole AC, current-limiting (application category A) with electronic and electromagnetic maximum current trip units. A3793C — 2-pole, selective (application category B) with an electronic maximum current trip unit. A3794C — 3-pole AC, selective (application category B) with an electronic maximum current trip unit. A3797C — 2-pole without maximum trip units. A3798C — 3-pole without maximum trip units. Included in the Minpromtorg register.
