AZK1M-3-2S
Aircraft Circuit Breaker
Description
AZK1M-3-2S: 3 A second-series circuit breaker
AZK1M-3-2S is the 3 A execution of the AZK1M-2S family of single-pole push-button circuit breakers. It protects DC and AC circuits against unacceptable overload and short-circuit current. The original Cyrillic marking is АЗК1М-3-2С. Both the current rating and the 2S suffix must agree with the approved wiring and parts data.

Construction
The designation identifies a push-button breaker with one protected pole and a metallized housing. The thermal release has free-trip action, so holding the button ON cannot prevent an automatic opening. A white ring is visible in the OFF state. The terminals, body profile, full marking and series suffix should be checked against the removed unit.
The 3 A value is a protective rating, not a statement of aircraft applicability or interchangeability. Related second-series entries AZK1M-2-2S and AZK1M-40-2S have different settings and are linked only for catalog navigation.
Electrical and environmental data
Documentation specifies up to 27 V DC and 115 V AC at 400 Hz or 320–1050 Hz. For AZK1M-3-2S, boundary current at +20 °C is not more than 1.6 times rated current; at −60 °C it is not more than 1.9 times rated current. Terminal voltage drop at rated current is limited to 500 mV, and maximum mass is 31 g.
Series data also gives −60 to +60 °C, relative humidity up to 98% at +40 °C, 3,000 rated-current switching cycles and 100 automatic overload trips from boundary current to 20 times rated current. These values must be reconciled with the passport of the supplied unit.
Ordering information
Verify the complete marking, current, series suffix, network voltage, AC frequency, terminals and mounting before installation. Inspect for cracks, overheating, corrosion and damaged hardware. Final acceptance follows the passport, 8Ю3.619.294 ТУ and approved aircraft documentation.
See Wikipedia on aircraft electrical systems and the Aviamisto Circuit Breakers category. State AZK1M-3-2S / АЗК1М-3-2С in the inquiry.
