Siemens 3RP1576-1NQ30 Electronic Timing Relay
Siemens 3RP1576-1NQ30 electronic timing relay with star-delta function.
The Siemens 3RP1576-1NQ30 is an electronic timing relay featuring a star-delta (wye-delta) starting function. It provides one delayed normally open (NO) contact and one instantaneous normally open (NO) contact. The adjustable time range is from 3 to 60 seconds. This relay operates on dual voltage inputs: 24V AC/DC or 100-127V AC at 50/60 Hz, utilizing screw terminals for connection.
This timing relay is designed for applications requiring controlled time delays, particularly in motor starting circuits where star-delta configurations are used to reduce starting current. Industries such as manufacturing, machine building, and automation systems benefit from its precise timing and reliable contact switching. Note that this product is phased out.
