Circuit breakers are safety-critical items. The same E-T-A products may be required to operate occasionally or very often during the life of the equipment they are protecting. Either way, operation must be dependable immediately a fault occurs. Any failure to perform could have disastrous consequences - endangering people and property.
We have been designing circuit protection since 1948. Over time, we have gained expertise on long term needs of circuit protection; the impact of ageing equipment, corrosion, deterioration of wiring insulation and loosening of connectors. To meet these stringent demands, E-T-A products are designed and manufactured to the highest quality at every stage of the manufacturing process and is verified by the latest automatic test equipment and SPC techniques.

 

 

Our test laboratories are equipped to conduct comprehensive electrical and environmental qualification program and work according to DIN EN ISO/IEC 17025 requirements.

 

Our substantial investment in research and development ensures that we remain at the forefront of technology. Our international standards committee involvement, covering many different industries, enables us to give advice on legislative demands and safety trends worldwide.

 

 

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).

 

Those products from the E-T-A program which are subject to the European Union EMC Directive have been CE marked since early 1996 to demonstrate compliance.  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 recognized test authorities.
