Use on twisted pair signalling applications which require either a lower in-line resistance or an increased current than the D or E Series.
Also suitable for DC power applications less than 4 amps.
Available for working voltages of up to 6, 15, 30 or 50 volts.
For some data and signal applications with lower current, higher in line resistance or higher bandwidth requirements, the D or E Series protectors may be more suitable. If the protector is to be mounted directly onto a PCB, use the ESP PCB/**D or ESP PCB/**E protectors.
Application
Use these applications to protect resistance sensitive or higher running current systems, eg systems with long signal lines, or DC power applications.
Two ESP 15H protectors mounted in a control cabinet
and earthed via the cabinets' earthed chassis.
Features and benefits
 Low let-through voltage between all lines.
Provides repeated protection in lightning intense environments.
Ultra low (<0.05Q) in-line resistance allows resistance critical applications (eg alarm loops) to be protected.
 |
Very high (4A) maximum running current.
Strong, flame retardant ABS housing.
Supplied ready for flat mounting on base or side.
Built-in DIN rail foot for simple clip-on mounting to top hat DIN rails.
Colour coded terminals give a quick and easy installation check —grey for the dirty (line) end and green for clean.
Screen terminal enables easy connection of cable screen to earth.
Substantial earth stud to enable effective earthing.
Integral earth plate enables enhanced connection to earth via CME kit.
UK Oftel approval NS/G/1235/W/100025.
