Siemens WLUV120 Undervoltage Release Relay AC

Siemens WLUV120 Undervoltage Release (UVR) is an accessory for the WL family of low-voltage circuit breakers that triggers an automatic trip when the incoming voltage falls below the preset level. It is rated for 120 VAC operation, with an instantaneous trip specification of 125 VDC/120 VAC, providing fast UV protection in control circuits. The WLUV120 is designed specifically for WL-frame breakers, making it suitable for industrial panels that rely on UV protection to prevent operation under undervoltage conditions. By supplying a reliable UVR option for WL-series breakers, it helps ensure safe disconnection and protects downstream equipment in applications requiring tight voltage monitoring.
