SAFETY SWITCHES
[11] The starting current of motors of more than standard horsepower may require the use of fuses with appropriate time delay characteristics.
[12] Std.—Using fast acting one time fuses. Max.—Using dual element time delay fuses. (Non-fusible switches have max rating unless noted.)
[13] Use outer switching poles.
[14] If used on corner grounded delta systems, install neutral and use outer switching pole for ungrounded conductors.See data bulletin 2700DB0202 for additional information.
[15] 480 Vac 1 Phase HP = 3 Std, 7.5 Max
[16] 10 Std, 15 Max
[17] 480 Vac 1 Phase HP = 5 Std, 20 Max
[18] 25 Std, 30 Max
[19] 480 Vac 1 Phase HP = 10 Std, 30 Max
[20] 40 Std, 50 Max
[21] Maximum HP
[22] Complete rating on switch is NEMA Type 3R, 5 or 12. For 3R applications, remove drain screw from bottom endwall.
[23] Maximum HP is 15 for corner grounded delta systems.
[24] Maximum HP is 30 for corner grounded delta systems.
[25] Use 75
o
C #4 Cu or #2 Al conductors only on DTU362 and DTU362RB.
[26] Use 75
o
C #1 Cu conductors only.
[27] 480 Vac, 250 Vdc maximum
