Advanced Distributor Products 110000245 Limit Switch 320788-703 which typically indicates a limitThe Advanced Distributor Products 110000245 Limit Switch is a high precision safety component engineered for HVAC equipment, specifically B, CP, F, MX, and S series air handlers. This 80 140F AUTO Limit Switch operates as a critical temperature control, automatically interrupting the electrical circuit if domestic heating or cooling temperatures exceed the 140F threshold. By monitoring these thermal operational limits, the ADP 110000245 prevents heat
