Protection for 4 twisted pair lines (ESP 06Q, ESP 15Q, ESP 30Q, ESP 50Q and ESP TNQ). Protection for three 3-wire RTD lines (ESP RTDQ). Available for working voltages of up to 6, 15, 30 and 50 volts, and telephone lines with a maximum working or ringing voltage of 190 volts.
Protectors for individual data and signal lines are the ESP D series, or ready-boxed to IP66 the ESP D/BX series. Alternatively, for individual protectors with higher current or bandwidth see the ESP E series. For individual 3-wire RTD applications see the ESP RTD
Application
Use these protectors where installation space is at a premium and large numbers of lines require protection. Typically used in process and petrochemical applications to protect supervisory, control and data acquisition systems.
ESP 30Qs mounted on a G DIN rail, protect 48 twisted pair lines.
Features and benefits
Protect four twisted pair lines (plus screens) in one compact unit (ESP 06Q, ESP 15Q, ESP 30Q, ESP 50Q and ESP TNQ).
ESP RTDQ protects three 3-wire lines in RTD applications.
Almost twice as space efficient as smallest competitor .
Standared DIN module (18mm) depth.
Removable (plug-in) terminals allow pre-wiring of cable looms for easier installation.
Built-in DIN rail foot for clip-on mounting to top hat or G DIN rails.
Optional flat mounting on side.
The Q series can be earthed via DIN rail or via the M3 threaded hole in the base (shown here).
2.5mm2 terminals allow for larger cross section wiring, stranded wires terminated with ferrules or fitting two wires into a single terminal.
Low let-through voltage between all line.
Provides repeated protection in lightning intense environments.
Very low resistance to minimise unwanted signal strength reductions.
Strong, flame retardant, ABS housing.
Colour coded terminals (grey for line, green for clean) give a quick and easy installation check.
Screen terminal enables easy connection of cable screen to earth.
Simple, yet substantial, connection to earth via DIN rail.
UK Oftel Approval NS/G/1235/W/100025.
A Q Series protector mounted on a top hat DIN rail. Note the plug-in terminals for easier installation in confined spaces.
Installation
Connect in series with the signal or data line either near where it enters or leaves the building or close to the equipment being protected. Install in a cabinet/cubicle close to the systems earth star point.
