0307-3191 Genset Relay Control Card, 24V, 2+1 Channel, for Cummins Genset

The 0307-3191  is a high-performance, heavy-duty Starting Relay (Magnetic Switch) specifically designed for Cummins diesel engines. It serves as a robust electromagnetic bridge, allowing low-current control signals from the ignition or a digital controller (like a DSE module) to engage the high-current starter motor. It is engineered to perform reliably under the extreme thermal and vibrational stress found in industrial engine bays.

Engine Compatibility This relay is a staple component for various large-bore and legacy Cummins platforms, including:

• ✅ Cummins NT Series: NTA855 and NT855 G-Drive engines (commonly used in power generation).

• ✅ UL5302NO1CO-2C-DP-72 Model number
  

• ✅ Cummins K-Series: KTA19, KTA38, and KTA50 high-horsepower industrial engines.

• ✅ Cummins V-Series: VTA28 series engines.

• ✅ Industrial Applications: Widely used in heavy-duty mining trucks, marine vessels, and large-scale standby generators.

Top 4 Technical Specs
