BDZ proof breaker manufacturer Zhejiang Songbei explosion-proof electrical equipment Co., Ltd. Hebei BDZ breaker purposes, Shijiazhuang explosion breaker much money, BDZ breaker factory direct proof, explosion-proof circuit breakers Which Shanxi, Shaanxi and explosion-proof circuit breaker product images, Inner Mongolia proof breaker specifications, Liaoning explosion breaker manufacturer and supplier proof breakers Data Details description 1, BDZ-proof breaker purposes, working conditions 1.1 uses BDZ-proof circuit breaker (hereinafter referred to as breaker) for Class II, Grade B or C grade, T6 group and containing explosive gas mixtures dangerous places below the level of groups, as the control AC 50Hz, rated voltage to 380V, rated current up to 100A, the control starting power to three-phase asynchronous motors of 50KW , stop, and overload, short circuit protection. 1.2 Working conditions a altitude over 2000 meters;. B ambient temperature of -20 ℃ ~ + 40 ℃;. C ambient air relative humidity less than 90% (+ 25 ℃ when); d in the absence of a significant shake and severe shock. vibration place; e in no damage to the metal and insulation corrosive gases; the main technical parameters in Table 2.2: Model Rated Current (A) controls the motor power (KW) Ex-mark 220V 380V BDZ □ -10 10 2.2 4 ExdeIIBT6 ExdeIICT6 ExdIIBT6 BDZ □ -20 20 3 5.5 BDZ □ -40 40 4 7.5 BDZ □ -60 60 5.5 11 BDZ □ -80 80 7.5 15 BZD □ -100 100 15 30 2.3 Structure Overview a. breaker in accordance with GB3836.1 ~ 3-2000 standard design and manufacturing, and inspection agencies designated by the State inspection issued proof certificate;. b circuit breaker breaker and explosion-proof composite circuit breakers, circuit breaker housing complex by a cast aluminum alloy die-casting, surface spray, high strength, beautiful appearance, the main chamber of explosion-proof structure, wiring chamber is increased structure. Flameproof enclosure inner circuit breaker element in the housing shell covered by a button or operating mechanism control, in order to control the motor starting, stopping purposes. Flameproof breaker housing is made of welded steel plate, surface spray, beautiful appearance, separates the main chamber and the implosion-type wiring compartment. 5. Technical Data Installation and maintenance 5.1 installation check the circuit breaker nameplate is realistic conditions of use. Note that the cable outlet opening 5.2 is installed by a metal gasket, seals turn into the terminal cavity, the outlet mouth tightened, so that the seal, then the pressure line board pressed to prevent cable pull off. As unused extraction means, it must be sealed closure. 5.3 breaker inside and outside the ground must be solid and reliable. Check before 5.4 flameproof joint surface run all fastening bolts are tightened, there is no spring washer promptly configuration, to prevent self-loosening. 5.5 Maintenance must disconnect the power before class, before opening the lid repair and other electrical components are not charged when the shell. 6. Ordering Information When ordering must specify the complete model product name, size and number of orders. Example: BDZ53-40 proof breaker, 40A, 12 units.
