Kromschroder Actuator IC20-60Q3E 88300081

The Kromschroder Actuator IC20-60Q3E (SKU 88300081) is a rotary actuator designed for precise controlled movement between 0 and 90 degrees. It operates on a 120 V AC supply with a frequency range of 50–60 Hz and provides a torque of 3 Nm. The actuator has a duty cycle of 100%, a storage temperature range of -20 to 40 °C, and a weight of 1980 g. It features voltage-free limit switches and an adjustable holding torque, and it stops at its current position when power is disconnected. The unit is certified to 2014/35/EU, 2014/30/EU, and DIN EN 60730-1, with a safety class of 1.

When selecting an actuator of this type, ensure the supply voltage, frequency, torque, and duty cycle match the application requirements. The actuator must be compatible with the control system's feedback potentiometer power rating (0.5 W) and cable cross-section (up to 4 mm²). Mounting should account for the line entrance configuration (3 x M20 plastic cable glands) and the ambient conditions, ensuring no condensation is permitted. Verify the angle of rotation and holding torque adjustments are suitable for the valve or damper being operated.

Common failures in actuators of this kind include loss of movement or erratic positioning due to worn gears or motor issues. If the actuator fails, the equipment may remain in a fixed position or fail to respond to control signals. Check the supply voltage, limit switch operation, and feedback potentiometer continuity. Also inspect for condensation or moisture ingress, which can cause electrical shorts.
