The E-T-A 1658 series thermal circuit breakers offer a compact and cost-effective solution for overcurrent protection in a variety of applications. Designed with a manual reset, cycling trip-free mechanism, these breakers meet international requirements and eliminate exposed current-carrying metal parts. They are approved by leading safety organizations including UL, CSA, VDE, and EN 60934 (IEC 60934), making them suitable for use in battery chargers, consumer products, power supplies, and motors. The 1658-G21-02-P10-20A variant features blade terminals and a 20A current rating, providing reliable protection for sensitive electronic circuits.
