Terminal blocks the environment
According IEC 60079-0, terminal blocks are so-called components. Therefore,
for use intrinsically-safe circuits, you not need type examination certificate.
We recommend blue terminals for clear identification and easy recognition. adhere the
creepage and clearance distances for use terminations and partition plates.
By definition, these are components that are required for the safe operation of
devices and protective systems, but without performing autonomous function
themselves. They are approved for the type protection equipment increased

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 serve the basis for extensive approvals
