Sylvania KTM34-15 Electromechanical Relay

The KTM34-15 is an electromechanical relay in the KTM34 family, manufactured under the Sylvania brand and historically also labeled as a Sylvania relay as KTM34-15 Sylvania Relay. As an electromechanical device, it provides a controlled electrical path between its coil input and its switched contacts, allowing a low-current control signal to energize a load circuit while keeping the two circuits electrically isolated. The KTM34-15 designation appears in older industrial catalogs (including Joslyn Clark/KTM references), identifying it as a specific model within the KTM34-series used for switching and control in industrial panels. The Sylvania branding note on the KTM34-15 reflects historical branding practices where Sylvania and Sylvania portions of the same product line were marketed under different names in various markets. This model is typically employed in legacy automation setups for sequencing, interlocking, or remote switching tasks in equipment controlled by a separate control circuit. Because KTM34-15 is part of an older series, it may be found in refurbishment projects or vintage equipment where original components are still in service.
