Automatic VA47-29, 6A, 1f

Circuit breakers VA 47-29 are modern switching devices equipped with electrothermal and electromagnetic protection against overcurrents. Circuit breakers VA 47-29 are designed to protect electrical circuits from overloads and short-circuit currents, as well as for operational control of sections of electrical circuits. Circuit breakers VA 47-29 are produced in water-, two-, three- and four-pole versions, with protective characteristics B, C, D; switches are installed on a mounting 35 mm din rail; comply with GOST R 50345-99 and TU2000AGIE.641.235.003. Design features of VA 47 switches 29 Setting the thermal release by screwing the adjusting screw into the metal base allows you to keep the settings unchanged during operation. The main contacts of the machine are coated with a silver-containing composition. The original design of the BA 4729 contacts minimizes losses between the switch terminals and the conductor. The moving contacts of the circuit breaker also have a silver coating, which increases their service life and durability. The VA 47 29 circuit breaker has a fast-acting release system that does not allow the short-circuit current to reach peak values. Possibility of arbitrary installation in space. Possibility to connect conductors up to 20 mm in diameter. Wear resistance: electrical - more than 6000 on-off cycles; mechanical -2000 on-off cycles. The structure of the symbol VA 47-XXX YZZ / X: VA - circuit breaker; 47- series number; XXX - modification designation; Y- type of protective characteristic (B, C or D); ZZ - rated current; X is the number of poles. Operating conditions of the VA 47-29 circuit breaker: Operating temperature range - from minus 40 ° C to plus 50 ° C; Altitude above sea level - no more than 2000 m. Relative air humidity at a temperature of + 25 ° C - 80%. Relative air humidity at a temperature of plus 50 ° C - no more than 40%. Working position in space - vertical, with permissible deviations of ± 90º in the horizontal plane.
