(1) gF is not available when In is 250A. (2) Ii max. = 13 x In. (3) 1.0 x IR or 0.5 x IR can be selected. Characteristic of neutral protection (tN vs. IN) is
identical to characteristic of phase protection (tR vs. IR). (4) When you specify gF on MCCBs with 3 poles the terminal block is automatically fitted to
connect with the external neutral CT for 3 phases 4 wires system. See terminal blocks in section 4.
