3RP2576-1NW30
The Siemens SIRIUS 3RP2576-1NW30 star-delta time-limited relay has a delay range of 3-60 seconds, a wide coil voltage range of AC/DC 12-240V, includes one normally open delay contact and one instantaneous contact, screw terminal wiring, and is suitable for star-delta reduced voltage starting control of motors.
Product Positioning
The SIRIUS 3RP2576-1NW30 is a dedicated timer relay for star-delta (Y-Δ) circuits in the Siemens SIRIUS 3RP25 series. It can be set with a delay of 3 to 60 seconds and is commonly used in reduced-voltage starting control circuits for medium and large motors.
Core Product Advantages and Features
Star-shaped delay function
It features dedicated logic for star-delta (Y-Δ) switching, simplifying the design of motor reduced-voltage starting circuits.
Delay range: 3-60 seconds
The delay setting range is 3 to 60 seconds, with a setting accuracy of 5% and a repeatability of 1%, and the action is stable.
Wide-range coil voltage
The coil voltage covers AC/DC 12-240V, and one part number can correspond to multiple control power supplies.
Dual-contact output design
It provides one set of delayed normally open contacts and one set of instantaneous contacts to meet the timing requirements of star-delta switching.
