Submersible motor professional circuit breaker switch DZ15LD-40/390 air 1.2 KW 2.2 KW 3 KW 4 KW 5.5 KW
DZ15LD type electronic motor is broken. A short circuit. Leakage automatic protector (motor protector, professional circuit breaker, DZ15LD submersible pump air switch)
According to statistics, every year there are many motors was destroyed, including for broken phase. Short circuit burned down more than 95%. So, to the country and caused a lot of fund waste. Small enterprises and the rural customers are using a knife and thermal relay protection, no reliable protection device.
In order to solve the above problem, developed protection: air pump, oil pump, submersible pump, grinding machine, blower, motor equipment such as professional circuit breaker.
Broken phase protection of air leakage of switch of advantages:
A, regardless of high pressure cascade fuse drop down, or low voltage insurance and broken, electromotor winding a phase no electricity cause phase lack run reliably protect, break the action time is less than 3 S phase.
In the modern industrial production process. Because three and power phase lack, broken by motor is burned up, and become one of the main reasons for the motor destroyed. Especially in some automatic control circuit, a large number of ac contactor, ac contactor use after period of time, contacts and cause damage "phase lack", the motor damage phenomenon common occurance. Therefore, three root power phase lack, broken phase that protect a people to study the hot topic of conversation. This company in actual work, according to the work principle of three-phase ac motor, this paper analyzes the main causes damage to the motor development. It is a kind of set up what is unique, reliable work convenient installation multifunctional protector. In fault appeared, can cut off power supply in time, realize the armor of the motor. This motor protector, except for its "ac contactor phase lack" protection functions, but also with good power grid phase lack protection, overload protection, leakage protection. Is hot relay of the electronic motor protector the renewal of new products. This series product has several models, appear on the market at present integrated motor protector, the protector in the can not load condition (motor not connected) can be in action after the break. But the actual fault protection is to point to in all in motor running interrupt phase can protect. No motor running, what is broken phase protection! Once connected motor, power cut in operation of whatever phase, or contactor contact undesirable broken phase, run the motor still broken phase in run to continue. Not a protection.
Second, the main technical indexes
Submersible professional breaker protection function: leakage. Overload, broken phase. Lack of equal;
Phase lack broken phase protection: electric machine Lord circuit in any of the phase without electricity, and, in the action time < 3 S
Overload protection: motor load current of 1.2 times rated current, protection movement response time < 60 S, and it has good inverse time characteristics;
Leakage protection; Protection movement is a < 0.3 S 75 MA
Working voltage: AC 380 V frequency 50 Hz
Use environment humidity:-5 ℃ bastions 40 ℃
Three, the product model and the corresponding motor power
DZ15LD-40/390
Working voltage 380 V rated frequency frequency 50 Hz, power has 1.5 KW, 2.2 KW, 3 KW, 4 KW, 5.5 KW. Specific models for DZ15LD-40/390 XXKW.
DZ15LD-100/390:
Working voltage 380 V rated frequency frequency 50 Hz, power has 5.5 KW, 7 KW, 9 KW, 11 KW, 15 KW specific models for DZ15LD-100/390 XXKW.
Note: the above XX represent each kw mean, please choose this product must choose suitable for their own use of the products.

Motor open phase protection switch, air switch) applied to ac 50 hz, rated voltage of 380 v, rated current 250 a circuit, and used as lack of phase, leakage protection, can also be used to prevent due to the damage of equipment insulation, fire danger caused by the grounding fault current. And can be used to protect circuits and motor overload and short circuit, open phase, leak, a line not frequent transformation and also the don't frequent starting of the motor.
