SAX - Secu Access
One device – two functions: the Secu Access (SAX) terminal/test block is designed to make installation, maintenance, and testing easier, faster and safer.
Mounted on a DIN rail or screw-mounted, the SAX serves as a terminal block with an advanced cabling system. Measuring or testing of secondary circuits is easily facilitated by inserting a SecuControl Test Plug or Test Probe (STP). High quality current shorting bars installed in the test plugs automatically and reliably protect against open Current Transformers, and every module is keyed to its appropriate test probe and test plug to prevent operator error.
The SAX is available in any length and combination of current, voltage, and signal modules to match your substation design. How does it work?
