Switching devices
Automatic circuit breaker AZR-30 is designed for automatic switch off of electrical users in case of overloads and short circuits in circuits of direct current with voltage up to 30V in fixed and mobile plants.
Can be used as switch-offs and protection elements of electrical equipment in different types of machines, including automobiles, tractors, railway and water transport.
Automats with “K” indexes are designed under red lamps and are different from those without such index in inking white paint on handle sidewall instead of luminous material.
Automatic circuit breakers AZR have a trip free mechanism which does not let hold contacts closed until bimetal plate is chilled down up to certain temperature.
Basic technical characteristics of AZR:
• Nominal voltage, V ...... 27
• Nominal current, А...... 2; 3; 4; 5; 6; 10; 15; 20; 30; 40; 50; 60; 70; 80; 90; 100; 125; 150
• Voltage decrease between movable and non-movable contacts buses, mV, maximum ...... 180
· Operating temperature of the environment, C …….. from -60 to +60
• Total warranty period, years ……. 10
