The switch AVM

Switches AVM - automatic air circuit breakers are designed for use in electric power units DC to 440 V AC up to 500 V with a frequency of 50 or 60 Hz, for conducting current in normal mode and the current is switched off at short circuits and overloads (hereinafter Pics), and also for infrequent (to RS per day) operative inclusions and switching-off of electric chains, including induction motors if their starting characteristics consistent with a protective characteristics of the switches.

The climatic types of performances: U3, PI, M(marine), T(tropical).

Alphanumeric designations types of switches AVM:

- AVM-4 switch rated current up to 400A (settings 120, 150, 200, 250, 300, 400A)

- AVM-10 - accordingly to 1000A (500, 600, 800, 1000A)

- AVM-15 - accordingly to 1600A (800, 1000, 1200, 1400, 1600A)

- AVM-20, respectively to 2000A(800, 1000, 1200, 1400, 1600, 1800, 2000A)

The Letter "C" (example AVM-4C) denotes the possibility of selective setup time the circuit breaker AVM when Pics.

The Letter "H" (prima AVM-15 NM) denotes neselektivno switch with time delay when Pics(with watch movements), as well as instantaneous when Pics (without movements).

The Letter "B" (AVM-In) - withdrawable version ( without the "In" is fixed)

Switches have two switching positions is enabled and disabled.

The inclusion and disconnect switches can be manual direct drive or manual remote drive (depending on the performance of the switch). Remote switching is carried out by motor drive, and remote shutdown - an independent trip or minimum the release voltage. Overcurrent protection is maximum tripping current. Minimum protection (at lower voltage) is the minimum trip voltage. The time delay at overload is achieved by clockwork, installed on maximum tripping current and short-circuit time delay is achieved when using mechanical retarder mechanism.
