Star-delta timer relay CRM-2T UNI 002470013

Star-delta timer – reliable motor starting

This timer, designated CRM-2T UNI, is a key element in electric motor starting systems. It is designed to operate in a star-delta configuration, which allows limiting the starting current and minimizing the load on the electrical network during motor start-up. This solution is particularly important in industrial applications where large motors are a common element of the infrastructure.

Function and application

The CRM-2T UNI timer is used to automatically switch the motor from a star to a delta connection after a set time. This process ensures a smooth and controlled start-up, which translates into a longer motor life and stable operation of the entire installation. It is an ideal solution for pumps, fans, compressors and other devices requiring high starting torque.

• Starting current limitation: The star-delta configuration reduces the current flowing through the motor windings at the moment of starting, protecting the electrical network from overload.
• Smooth start: Gradual switching to the delta connection ensures a gentle start-up process, minimizing mechanical stress on the motor and connected devices.
• Versatility: The CRM-2T UNI timer is compatible with various types of motors and electrical installations.
• Modular design: Allows easy integration with existing control and automation systems.

Construction and mounting

The CRM-2T UNI timer is characterized by a compact modular design, which facilitates its mounting on a standard TH35 rail. Solid construction guarantees reliable operation in harsh industrial conditions. Installation is intuitive and does not require specialized tools – simply snap the timer onto the rail and connect the wires according to the connection diagram. This allows installers to quickly and efficiently implement it into existing control systems.
