An Introduction to E-T-A Circuit Protection
E-T-A Reliable Protection for Demanding
Applications
E-T-A Approvals
E-T-A circuit protection products are designed according to IEC
requirementsforCBEs(IEC934, EN60934)-definedascircuitbreakers
for equipment where unrestricted short circuits either cannot occur or
are limited by back-up protection elsewhere in the system.
E-T-A circuit breakers are designed for equipment, component and low
voltage wiring protection. Their precision performance characteristics
are ideally suited to applications for which other methods of protection
are generally inadequate. These include:

Most E-T-A models are fully approved by leading authorities including
VDE, CSA and UL (supplementary protectors in accordance with
UL 1077). Furthermore approvals are also held from specialised
agencies such as the UK Civil Aviation Authority, Lloyds Register of
Shipping, Bureau Veritas and the American Bureau of Shipping.

CE Mark
Those products from the E-T-A programme which are subject to the
European Union EMC Directive have been CE marked since early 1996
to demonstrate compliance. Declarations of conformity contain the
necessary supporting evidence.
In addition, from January 1997, models covered by the Low Voltage
Directive have also been CE marked.
CE marking is the responsibility of individual manufacturers and should
not be confused with formal approval logos, the use of which is
administered by recognised test authorities.
