The electrical system, external to the unit, may constrain the actual current rating achieved in a particular installation.

Rating is considered as the current capability of the protector for equipotential bonding near the service entrance.

If you desire a protector with an extra high maximum surge current use the ESP M2
or M4 series. If your supply is fused at 16 amps, or less, the in-line protectors (ESP
240 (or 120-5A (or -16A) and their ready boxed derivatives) may be more suitable.
If you need to mount the display panel separately from the main protector unit, use
the ESP M1R series.
Surge Protection devices have been designed to be installed on the left hand
side of all distribution boards and MCCB panelboards.
