ABB Measurement & AnalyticsMotor Temperature Monitoring UnitSD241-B
Description
General specifications:
Motor temperature monitoring unit SD241-B – for Contrac actuators in explosion proof design – Thermistor control unit for monitoring the motor temperature – Integrated contactor for interrupting the power supply – Test button on the front – Signal contact to monitor the trip function
Contrac save & restore engineering tool for electrical actuators ECOM700 – Using the engineering tool ECOM700, the user can read out, store and write back the actuator-related data from the electronic unit of a Contrac actuator
Adater plates for rotary actuators – Steel plate including fixing screws for mechanically adapting lever actuators (model series PME, RHA…, RHB…, RHD…, and RHDE…) to existing fixing devices for lever actuator types RH… – Enables faster replacement – Avoids additional installation costs – Operating level of actuating lever and coupling rods remains unchanged

Datasheet
Datasheet Summary Powered by GS/AI
The SD241-B is a motor temperature monitoring unit designed for Contrac control actuators in explosion-proof design, featuring an integrated contactor to interrupt power supply upon thermal overload. It uses PTC thermistors to monitor winding temperature and employs a closed-circuit self-monitoring principle. The unit has a plastic IP54-rated housing, a front-mounted test button, and a signal contact for trip function monitoring. It operates with AC line voltages of 115 V or 230 V at 50/60 Hz and includes a 16 A time-lag backup fuse and a 4 A fast-acting fuse. Operating temperature ranges from −25 to 60 °C, with storage temperatures up to 70 °C. It complies with PTB 01 ATEX 3218. Dimensions are 210 mm × 126 mm × 55 mm.
