Ground-to-line protection, line-to-line protection. Low series impedance, easy installation; discharge current 10KA/line, 20KA/surge protector (8/20μs); response time less than 10ns. Used for twisted pair signal transmission. It requires low in-line resistance, higher bandwidth than the D series, or an increased current. Also suitable for DC power supplies less than 1.25A. Suitable for equipment with maximum operating voltages of 6, 15, 30, or 50V. Protects industrial control equipment connected by signal lines; data communication systems; 4-20mA loop lines; telephone systems; remote control/telemetry contacts.

1. Low insertion impedance minimizes signal attenuation.
2. Suitable for current signals, data signals, and standard pulse signal system protection.
3. Low let-through voltage provides the most effective equipment protection.
4. Sturdy, flame-retardant ABS housing for use in various hazardous environments.
5. High current-carrying capacity, capable of handling up to 20KA lightning current, especially suitable for environments with high thunderstorm days.

Applications:
1. Suitable for protecting various control equipment I/O cards, such as 4-20mA loops, thermocouples, shutdown systems, flame and gas detectors, CCTV telemetry, CCTV telemetry/control lines.
2. Suitable for systems with operating voltages of 6V, 15V, 30V, and 50V.

Performance and Advantages:
1. Low let-through voltage across all lines.
2. Provides repeated protection in lightning-prone environments.
3. Low insertion impedance minimizes unnecessary signal strength attenuation.
4. Sturdy, flame-retardant ABS housing.
5. Easy to mount flat on the base or side.
6. Built-in DIN rail clips for easy installation on the top of DIN rails.
7. Color-coded terminals for easy identification during installation—gray indicates the hazardous end, green indicates the non-hazardous end.
8. Sheath terminals facilitate grounding of cable sheaths.
9. Robust grounding plate enhances grounding through CME component connections.
10. UK Oftel certification NS/G/1235/W/100025.
