The TH-T25KP9A is a Mitsubishi solid state overload relay from the TH-T series, built for motor protection in control panels and industrial machinery. It sits between the contactor and the motor circuit, monitoring current and tripping on overload without mechanical bimetals — meaning no drift over time and a faster reset than a thermal relay.
For a procurement decision: quote against an RFQ to confirm lead time and pricing for your quantity. The TH-T series is a standard line, so lead times are generally predictable.
