Description:
One crucial safety relay used in electric locomotives is the ground relay (GR). Here are some essential details regarding how it operates: It finds ground problems in the traction motors and circuits of locomotives. This guards against harm to the equipment. It tracks the current that travels from the locomotive’s wheels to the earth. Normally, this is quite close to zero. Current will return to the locomotive body through the soil in the event of a ground fault. When GR notices this, the circuit breakers trip.
Specification:
- Operating Voltage: 74vdc
- Pickup Voltage: 48vdc max
- Pickup current: 0.750 to 0.825 amp
- Contacts: 4 N.O & 2 N.C
- Coil Resistance: 0.86 Ω
Applications:
All types of EMD locomotive models controlling system cabinets.

Applications:
All types of EMD locomotive models controlling system cabinets.
GENERAL PURPOSE RELAY 3 POLE
OEM PART NO. 8357415
Description:
Often referred to as a multi-purpose relay, a general-purpose relay is a straightforward electromechanical relay intended for a broad range of switching and control applications. A magnetic field produced by the activated coil pulls the armature and shifts the contacts’ positions. There are three types of contacts: changeover, typically closed, and normally open. Permit several circuits to be controlled.
Inexpensive, simple to use, swap out, and maintain. incredibly adjustable with a wide range of choices. Proven and reliable technology.
Specification:
- Contact Rating: 10Amp 74VDC
- Coil Rating: 1128Ohms +/-15
- Pickup: @48VDC
- Drop out: @5-32 VDC
Applications:
This is for all EMD Super series Locomotives models.
