Selection Notes

• Rated current is 63 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 TMD trip unit is thermal-magnetic; check the thermal setting and magnetic trip values in the ABB catalog against the load and the protection coordination plan.
