Product Overview
GE C137M Stud-Mount SCR for Industrial Power Control
This component serves as a gated power-switching device used to manage controlled current flow in rectifier and control circuits. Designed for reliable triggering and sustained conduction, it fits applications requiring deliberate on-off control rather than continuous regulation. A common reference point is AC / DC power control, where predictable switching behavior matters as much as mechanical robustness.
Product Condition
Unused, New Old Stock. This SCR has not been put into service and comes from older inventory retained for industrial or service use.
Product Overview
The General Electric C137M is a silicon controlled rectifier built in a stud-mount package for secure mechanical and electrical attachment. As a three-terminal thyristor, it conducts only after a gate signal is applied and continues conducting until current drops below its holding threshold. Components in this class are widely used where repeatable, gated conduction is required in industrial power circuits.

Frequently Asked Questions
What type of device is the GE C137M?
It is a silicon controlled rectifier, also known as a thyristor, designed for gated control of electrical current.
How is this SCR mounted?
The C137M uses a stud-mount package, allowing it to be mechanically fastened to a chassis or heatsink.
Does this part work with AC or DC circuits?
SCRs of this type are commonly used in both AC phase-control and DC switching applications.
Why is New Old Stock useful for industrial parts?
New Old Stock components provide original-manufacture parts for maintaining or restoring equipment that specifies legacy GE devices.
You can install this SCR in a phase-controlled rectifier circuit, using its stud-mount construction to fasten it to a heatsink and apply gated turn-on control within an existing power-switching assembly.
