Detailed Description:
Twisted Pair Data Line, Signal Telephone Line Lightning Protector
Models: ESP 06Q, ESP 15Q, ESP 30Q, ESP 50Q, ESP TNQ, ESP RTDQ
Suitable for protecting twisted pair lines with a maximum operating voltage or ringing voltage of 190V.
ESP Suitable for protecting one pair of twisted wires
ESP Suitable for protecting four pairs of twisted wires
Application
Used for standard pulse signal lines, i.e., lines used on modems and computer communication interfaces.
Performance and Advantages
Compact structure, capable of protecting up to four twisted pairs (with sheath).
Standard DIN module depth (18mm).
Built-in DIN rail for mounting on DIN rail top seats.
Optional side flat mounting.
Terminals for 1.5mm² or 2.5mm² allow large cross-section twisted pairs to be terminated via ferrules.
Low let-through voltage between all lines.
Repeated protection in environments with frequent lightning occurrences.
Low insertion impedance, minimizing unnecessary signal attenuation.
Sturdy, fire-resistant, ABS outer casing.
Color-coded terminals for easy installation—gray indicates the hazardous end, green indicates the non-hazardous end.
Sheath terminals facilitate grounding of cable sheaths.
UK Oftel certification NS/G/1235/W/100025.
