Note: 1. Unit is designed for top and bottom cable entry for all services and load.

2.Enclosures for 600 – 3000 amps are freestanding.

3.Consult ASCO for type 3R, 4 and 12 enclosure weights and dimensions.

4.When temperatures below 32° F can be experienced, special precautions should be taken, such as the inclusion of strip heaters, to prevent condensation and freezing of this condensation. This is particularly important when environmental enclosures (Type 3R, 4 & 12) are ordered for installation outdoors. See Optional Accessories page for space heater options (acc. 44G).

Note: All Series 300SE switches are furnished with a solid neutral plate (unless switched neutral configuration is specified) and terminal lugs.

* 200 amp rated switch for use with copper cable only.
