The Schneider Electric S33595 is a full-function test kit (FFTK) designed for comprehensive testing and evaluation of circuit breaker trip units in a wide range of industrial power distribution systems. It enables field technicians, electrical maintenance teams, and commissioning engineers to verify the performance of protective trip functions, including overload, instantaneous, and ground-fault responses. This test kit supports both automatic and manual testing, as well as mechanical operation and inhibit functions (such as Zone-Selective Interlocking and thermal imaging inhibit) to assess the behavior of trip units under controlled fault conditions. It is compatible with multiple circuit breaker families, including PowerPact, Masterpact, and Compact breakers, making it a versatile and essential tool for ensuring that protection devices operate correctly and reliably before placing electrical equipment into service or during routine maintenance.
