UVR-1SDA063552R1

The ABB UVR-1SDA063552R1 is a Shunt Trip Coil (also known as an Under-Voltage Release or Opening Release) for ABB's Molded Case Circuit Breakers (MCCBs). It is an electromechanical accessory that enables the remote tripping or opening of a compatible circuit breaker on command. It does NOT provide undervoltage protection; it simply triggers the breaker's opening mechanism when its coil is energized.

Technical Parameters Parameter Description / Value Manufacturer Part Number UVR-1SDA063552R1 Product Type Shunt Trip Coil / Remote Opening Release Compatible Breaker Series ABB Tmax XT MCCBs (e.g., T1...T7 frames). Must verify specific compatibility list. Operating (Trip) Voltage AC 230V, 50/60 Hz (This is a common rating for this part number. Must be confirmed via datasheet as other voltages exist). Coil Power Consumption Typically ~15-20 VA (inrush), ~3-5 W (holding). Mechanical Operation Instantaneous. When energized, it trips the breaker. It requires manual reset of the breaker handle after tripping. Electrical Connections 2 screw terminals (for control circuit wiring). Mounting Position Side-mounted on the left or right side of the compatible MCCB (depends on breaker model). Insulation Voltage Suited for control circuits up to 250V AC. Ambient Temperature Typically -25°C to +70°C (operational). Standard IEC/EN 60947-2
