E-T-A Approvals

E-T-A circuit protection products are designed according to IEC requirements for CBEs (IEC 934, EN 60934) - defined as circuit breakers for equipment where unrestricted short circuits either cannot occur or are limited by back-up protection elsewhere in the system.

Most E-T-A models are fully approved by leading authorities including VDE, CSA and UL (supplementary protectors in accordance with UL 1077 or CSA C22.2 No. 235-M89 or circuit breaker to UL 489/ 489A). Furthermore approvals are also held from specialised agencies such as the UK Civil Aviation Authority and Bureau Veritas.
