The Schneider Electric TMC2AQ2C is a compact circuit breaker from the Multi 9 / Acti 9 series (specifically the TMC2 range). It is a 1P+N (single pole + neutral) residual current circuit breaker (RCBO) that combines overcurrent protection (magnetic and thermal) with earth fault (leakage current) protection in a single device. This integrated device is designed to protect electrical circuits against short-circuit, overload, and earth leakage faults, primarily in residential, commercial, and light industrial installations.
