ESP Q & TNQ Series
Technical specification
The ESP Q Series is also available for protection of RS 485 and RTD applications (ESP RS485Q, ESP RTDQ). Protectors for individual data and signal
lines are available (ESP D Series and Slim Line ESP SL Series), or ready-boxed to IP66 (ESP **D/BX etc). Alternatively, for individual protectors with
higher current or bandwidth use the ESP E and ESP H Series.

1 Nominal voltage (DC or AC peak) measured at < 5 µA
(ESP 15Q, ESP 30Q, ESP 50Q, ESP 110Q) and < 200 µA
(ESP 06Q).
2 Maximum working voltage (DC or AC peak) measured at
< 5 mA leakage (ESP 15Q, ESP 30Q, ESP 50Q, ESP 110Q) and
< 10 µA (ESP TNQ).
3 The maximum transient voltage let-through of the protector
throughout the test (±10%), line to line & line to earth,
both polarities. Response time < 10 ns.
