(1) 600 A devices are derated to 540 A for resistance heating loads when aluminium wire is used.
(2) Types L and LX contactors also have a ballast lamp rating of 15 A/
a
347 V when connected single-pole to load and a 600 V when connected 2-pole to load on
single-phase and 3-pole to load on 3-phase.
(3) Resistance heating only (3-phase system).
(4) Select lighting contactor on basis of rated motor voltage, whether non-motor load is connected line-to-line or line-to-neutral.
(5) 30 kA also applies for Class J and Class K5, time-delay, 600 A maximum fuses. Additionally, 30 kA ratings apply to Class T, 1200 A maximum and Class L,
1600 A maximum fuses.
