Upgrade the protection of your circuits with the thermal circuit breaker ST-1 by Aier, a technologically superior and reusable alternative to conventional fuses. Its core operation is based on a sensitive thermal mechanism with a bimetallic strip, which accurately detects overload and short circuit conditions. When the current exceeds the rated value of 10A, the breaker automatically interrupts the supply, protecting your sensitive equipment from permanent damage. Unlike single-use fuses, the ST-1 features a reset mechanism (push-to-reset), allowing immediate restoration of the circuit after the fault is resolved, thus reducing downtime and replacement costs. The dual certification for operation at voltages up to 250V AC or 32V DC makes it ideal for a wide range of applications, from safety power strips and UPS power supplies to industrial control panels, generators, and marine electrical systems.
