AZZK-7.5

Construction and versions

The catalog construction uses a compact brown phenolic housing between metal plates, one manual actuator and three power terminals. This card represents the AZZK version with a extended non-luminous actuator for installation in a cockpit with red lighting. The catalog reference dimension H is 99 mm and the corresponding actuator dimension l is 36.5 mm.

Identification should compare the full AZZK-7.5 marking, rated current, actuator version, terminal arrangement and mounting dimensions. A similar case or matching current alone does not establish interchangeability. Related entries AZZK-3 and AZZK-4 are provided for navigation and carry their own protective settings.

Electrical and environmental data

The manufacturer catalog specifies a 200 V three-phase AC circuit with a +7/−13 V tolerance, frequency 400 ±40 Hz and load power factor not less than 0.5. For AZZK-7.5, the thermal-release trip current is 1.5 times rated current. At an ambient temperature of +60 °C, the stated thermal-release operating time is up to 30 minutes.

Family operating limits are −60 to +60 °C and up to 98% relative humidity at +40 °C. Maximum mass for the 2–50 A construction is 280 g. These catalog values identify the family and rating; acceptance of an individual unit still follows its passport and 8Ю0.361.030 ТУ.

Ordering information

Before installation, inspect the phenolic case, metal plates, actuator, three terminals and mounting points for cracks, overheating, corrosion or unspecified repair. Confirm the line voltage, frequency, current rating, three-pole circuit and AZZK handle version against the approved wiring and parts data. Functional testing must use an authorized bench procedure.
