Selection Notes

• Rated current is 1250 A; check it against the continuous load current of the circuit being protected.
• Icu is 70 kA at 400 V AC; confirm it is equal to or higher than the prospective fault current at the installation point.
• This is a 3-pole version for three-phase circuits; select a 4-pole variant if the neutral must be switched. Mounting is fixed (not plug-in or withdrawable).
• The PR231/P LS/I is an electronic trip unit with long-time (L), short-time (S) and instantaneous (I) protection, so thresholds can be coordinated with upstream and downstream devices.
