Siemens Industrial Controls 3RB3016-2SB0 3-12Amp Overload Manual Reset

The Siemens Industrial Controls 3RB3016-2SB0 is a vital safety component often found in various HVAC equipment like furnaces, air conditioners, and heat pumps. It serves as a manual reset overload protector with a 3–12 amp capacity, protecting sensitive components from electrical overloads that could cause harm. The 3RB3016-2SB0's internal mechanism trips, and power flow is stopped when an excessive current is detected due to the heating of the bimetallic strip. It is possible to manually restore power by pressing the reset button when the overload has subsided and the bimetal has cooled. By shielding vital electrical components from burnout, this function avoids expensive equipment damage and possible safety risks. Its small size and simplicity of installation also make it appropriate for a range of HVAC system applications.
