Therefore,
for use intrinsically-safe circuits, you not need type examination certificate. They serve the basis for extensive approvals.
Terminal blocks the environment
According IEC 60079-0, terminal blocks are so-called components.
C.
Terminal blocks for intrinsically-safe circuits “i” are passive components.
Explosion protection
Worldwide, explosion protection essentially based the international
IEC 60079 series standards, European and American norms, standards, and
directives.36 CAT1 Version 2025

Standards and industries
.
By definition, these are components that are required for the safe operation of
devices and protective systems, but without performing autonomous function
themselves. Numerous standards describe what has considered
in environments.
We recommend blue terminals for clear identification and easy recognition. adhere the
creepage and clearance distances for use terminations and partition plates.
These, well the accessories, have comply with the type according to
EN 60079-11. Thus, the application approved the type protection
„Increased Safety“ Zone and 2. The worldwide requirements are confirmed certification
according IECEx.Principles for the use terminal blocks Ex-areas
Harsh industrial environments and explosive risk zones, such the oil and
gas industry, make extreme demands safety, robustness and quality of
products and devices. They are approved for the type protection equipment increased
safety „e“ and are not marked with the mark according the European ATEX
directives 2014/34/ EU. the USA, the National Electrical Code (NEC) and Canada the
Canadian Electrical Code (CEC) form the basis.
