Detailed Description:
Twisted Pair Data/Signal Line Surge Protector
Models: ESP 06H ESP 15H ESP 30H ESP 50H
Applied to twisted pair lines requiring D or E series protection but needing lower insertion impedance or higher current capacity
Also suitable for DC systems with operating currents below 4A
Compatible with systems operating at 6V, 15V, 30V, and 50V
Performance and Advantages
Low let-through voltage between all lines.
Provides repeated protection under frequent lightning conditions.
Extremely low insertion impedance (<0.05Ω) enables protection for resistance-sensitive devices (e.g., alarm loops).
Maximum pass-through current of 4A.
Robust, flame-retardant ABS housing.
Easy base or side flat mounting.
Built-in DIN rail clip for convenient installation on DIN rail top seats.
Color-coded terminals for easy identification—gray indicates hazardous end, green indicates non-hazardous end.
Sheath terminal for grounding cable sheaths.
Robust grounding bolt ensures effective grounding.
Built-in grounding plate enhances grounding via CME component connection.
