Description
AZR-2: 2 A DC network protection circuit breaker
AZR-2 is the 2 A execution of the AZR single-pole circuit-breaker family for DC networks up to 30 V. The original Cyrillic designation is АЗР-2. It automatically disconnects a consumer during overload or short circuit and can also provide manual switching in the specified circuit.

Construction
AZR uses a dust- and splash-protected metal housing, lever control, two electrical terminals and a free-trip connection between control and contact mechanisms. Holding the lever in ON does not prevent automatic operation. The family is designed for ordinary panel illumination; K-suffix versions use a white-painted handle end for red-lit panels.
Confirm the 2 A marking, 30 V class and complete designation on delivery. Related Related versions: AZK3-35 and AZK3-40.
Operating data
The nominal network voltage is 27 V DC ±10%. Maximum voltage drop between moving- and fixed-contact buses, excluding the bimetal circuit at rated current, is 180 mV. The operating range is −60 to +60 °C, duty is continuous and endurance is 10,000 make-break cycles at rated resistive load.
Mounting uses two screws. Protection is IP30 for the enclosure and IP00 at the terminals; climatic categories are UHL3 and T3. These family data do not replace current-specific trip calibration, terminal torque or the product passport. Receiving inspection should record the marking, lever action, terminal condition and match to the approved feeder schedule before installation.
Inspection and inquiry
Inspect the case, lever, cover fasteners, nameplate, insulating base and terminals for cracks, overheating, corrosion, looseness or unspecified repair. Verify rated current, network voltage, conductor size and mounting spacing before installation. Wikipedia provides general context on circuit breakers. Browse Aviamisto’s Circuit Breakers category. State AZR-2 / АЗР-2, quantity and documentation in the inquiry.
