Aircraft Circuit Breaker
Description
AZRGK-50: 50 A sealed aircraft DC circuit breaker
AZRGK-50 is the 50 A execution of the sealed AZRGK single-pole circuit-breaker family for aircraft DC networks. Its original Cyrillic designation is АЗРГК-50. The device combines feeder protection against overload and short circuit with manual single-pole switching. A free-trip mechanism opens the contacts even if the control lever is held in the ON position.

Sealed construction
The family uses a narrow reddish-brown molded insulating enclosure, brass front plate, lever control and two power terminals. The AZRGK execution uses a longer handle without a luminous eye at its end and is intended for panels with red illumination. This control is the external distinction from the non-K AZRG execution.
Overall dimensions are 55.5 × 21.5 × 88 mm and mass is 121 g. Confirm the physical 50 A marking, full designation, terminal arrangement and panel-lighting execution on the supplied unit. Related versions: AZRGK-25-2S and AZRGK-50-2S.
Electrical data
The nominal network value is 27 V DC ±10%, duty is continuous and the specified switching endurance is 10,000 operations. For ratings from 25 to 50 A, the specified network inductive time constant is 0.001 s. The release construction for this card is described as thermal overload release with free-trip mechanism.
OST 1 00195-76 gives a permissible prospective short-circuit current of 5000 A for AZRGK-50 under its stated 30 V DC test conditions. The standard table gives a response time of 0.005 s. Select the exact execution according to its trip characteristic, conductor size, terminal torque, mounting requirements and product passport.
Ordering information
Inspect the molded housing, front plate, extended lever, fasteners and terminals for cracking, overheating, corrosion, looseness or unspecified repair. Verify rated current and the sealed-family designation against the feeder schedule before installation. Wikipedia provides general context on circuit breakers. Browse Aviamisto’s Circuit Breakers category. State AZRGK-50 / АЗРГК-50, quantity and required documentation in the inquiry.
