Product information

Description

The Relpol RPC-2SD-UNI is a professional star-delta time relay engineered for precise control in industrial motor starting applications. This device is designed to manage the transition between star and delta connections, effectively reducing the inrush current during the startup phase of three-phase induction motors. With a universal supply voltage range of 12-240V AC/DC and a versatile timing range spanning from 1 second to 1 hour, it offers high flexibility for various automation requirements.

Advantages

This relay stands out due to its universal power supply compatibility, which simplifies inventory management and installation across different electrical systems. The robust design ensures reliable operation in demanding industrial environments, while the precise timing mechanism allows for accurate adjustment of the star-delta transition period. Its compact construction facilitates easy integration into standard control cabinets, and the high-quality output contact ensures long-term durability and consistent performance in motor control circuits.

Suitable for

  • Industrial motor starting systems
  • Three-phase induction motor control
  • Automation of machinery startup sequences
  • Electrical control panels requiring star-delta switching

This relay may not be suitable for applications requiring high-current switching directly through the relay contacts, as it is intended for control circuit signaling rather than direct power distribution to large motors. It is also not designed for environments with extreme moisture or corrosive gases unless housed in an appropriate protective enclosure.

Key specifications

  • Output: 1P (one changeover contact)
  • Timing range: 1 second to 1 hour
  • Supply voltage: 12-240V AC/DC
  • Frequency: 50/60 Hz
  • Function: Star-delta transition

To use the Relpol RPC-2SD-UNI, mount the device onto a standard DIN rail within your control cabinet. Connect the power supply to the designated terminals, ensuring the voltage is within the specified 12-240V AC/DC range. Configure the desired timing interval using the adjustment dial on the front panel. Once powered, the relay will automatically manage the timing sequence for the star-to-delta transition according to the set parameters.

What to consider before purchase

  • Verify that the control circuit voltage matches the relay specifications
  • Ensure the timing range meets the specific startup requirements of your motor
  • Confirm space availability on the DIN rail for installation
  • Check compatibility with existing motor contactors
Usage recommendations: Always ensure that the power is disconnected before performing any wiring or adjustments to the relay. Periodically inspect the terminal connections to maintain optimal electrical contact and prevent overheating in the control panel.
