Kromschroder Actuator IC50-60H30TR10 74215225

The Kromschroder IC50-60H30TR10 (SKU 74215225) is an actuator designed for rotary movement from 0 to 90 degrees, with a torque of 30 Nm. It operates on a 24 V AC supply voltage at 50–60 Hz and uses three-point step control. The actuator includes a feedback potentiometer of 1000 Ω with a maximum power of 1 W and a maximum wiper current of 0.1 A. It has a duty cycle of 100%, an IP enclosure rating, and safety class I. The device weighs 2.3 kg and is certified to EN 60730:2011, complying with directives 2014/35/EU and 2014/30/EU.

When selecting an actuator of this type, verify the supply voltage, frequency, torque, and control signal compatibility with the existing system. Ensure the mounting dimensions and shaft connection match the valve or damper. Check the feedback potentiometer resistance and wiper current ratings to match the controller. The actuator should be installed in a location where condensation is not permitted, and the ambient temperature must be within the specified range.

Common failures include loss of torque or inability to hold position, often due to worn gears or motor issues. The actuator may fail to respond to control signals, indicating electrical faults or damaged wiring. Feedback potentiometer wear can cause erratic position readings. Check for proper voltage supply, secure connections, and mechanical binding.
