Product Description
Key Features
- Rated current and motor power: At 400 V and 40 °C, rated operational current is 47 A in standard circuit and 81 A in inside-delta circuit; supplied motor power is 22 kW and 45 kW respectively.
- Soft starter functions: Has an integrated bypass contact system, thyristors, intrinsic device protection, motor overload protection, evaluation of thermistor motor protection, external reset, adjustable current limitation, and a motor brake output.
- Operating voltage: Rated operating voltage is 200 … 460 V in both standard circuit and inside-delta circuit, with -15 % relative negative tolerance and 10 % relative positive tolerance.
- Control supply and connections: AC control supply is 230 V at 50 Hz and 60 Hz. Main current circuit uses box terminals; auxiliary and control circuits use spring-loaded terminals.
- Mounting and dimensions: Dimensions are 170 mm width, 192 mm height, and 270 mm depth. Fastening is by screw fixing; mounting is on a vertical surface with the stated rotation and tilt limits.
- Protection and lifecycle: Front protection is IP20 with finger-safe protection for vertical contact from the front. Product lifecycle data states: Start of final year of support.
Applications
- Motor overload protection: Provides motor overload protection.
- Thermistor motor protection: Evaluates thermistor motor protection.
- Motor braking: Provides a motor brake output.
