Siemens 122816C Under Voltage Release Relay 48 VDC

Siemens 122816C is an undervoltage release relay (UVR) in the SBUV48 family, featuring a 48 V DC coil. This accessory is designed to be installed with Siemens low-voltage circuit breakers to trigger a trip if the supply voltage falls below a defined threshold, providing a safe, defined shutdown in motor drives, distribution panels, and control circuits. The 48 V DC coil rating aligns with common Siemens UVR components used in 48 V control schemes, enabling straightforward integration with 48 V logic and control power. Typical applications include industrial machinery, process equipment, and panelboard assemblies where maintaining reliable undervoltage protection is essential to prevent partial energization or equipment damage. Installation follows Siemens UVR mounting and wiring conventions to ensure safe, compliant integration by qualified personnel.
