EAC Certificate of Conformity No. EAEU KG417/033.UA02.00261. In the USSR automatic circuit breakers A3722P, A-3722P, A 3722 P, A 3722P were widely used in Ukraine, Estonia, Latvia, Azerbaijan, Sri Lanka, France, Georgia, Armenia, Lithuania, Greece, Kazakhstan, Moldova, Lithuania, Kirghizia, Uzbekistan, India, South Korea, Bulgaria, Iraq, Romania, Sudan, Egypt, Vietnam, Mongolia, Brazil,Macedonia, Serbia, Algeria, Turkey, Ethiopia, Oman, Qatar, Czech Republic, Slovenia, Ethiopia, China and other countries of near and far abroad - in Asia, in Europe, in South America, in Africa, in Middle East. We manufacture automatic switches A3722P, A-3722 P, A3722-P using the technology we have previously improved that was previously used at GP KhEMZ. Selling high current switch A3722P - new.
Automatic switches of type A3722P are designed for conducting current in normal mode, for selective protection in case of short circuits, for protection during overloads of unacceptable duration and for infrequent (up to 30 times a day) operational switching-on and switching off of electrical circuits with voltage up to 380V AC of frequency 50Hz or 400Hz .
Switches A3722P are manufactured in stationary version with electromagnetic maximum and semiconductor current releases.
Switches A 3722P can be equipped with an independent release, free contacts, electromagnetic drive, manual remote drive.
The main technical characteristics of switches A-3722P:
1. Rated current, A 250.
2. Application category A.
3. Rated currents of semiconductor releases (РП), А 80, 160, 200, 250 (at 400 Hz to 200А).
4. Adjustable values of rated working currents IR, A: -
5. The initial operating current in the zone of the overload currents, multiples of the rated operational current of the RP-.
6. Set-point according to the response time in the overload current zone, s: -
7. Settings for the response time in the zone of short-circuit currents-any.
8. Settings for the operating current in the zone of short-circuit currents, multiples of the rated working current - 800A, 960A, 1000A, 1100A, 1200A, 1400A, 1600A, 2000A and 2500A.
9. Rated short-time withstand current, kA 5.
10. Rated operating short-circuit breaking capacity, kA 7.5.
