NEMA Type
4, 4X, 5
Stainless Steel
NEMA Type 12
Visible blade heavy duty safety switches are designed for application where maximum
performance and continuity of service are required. All heavy duty safety switches
feature quick-make, quick-break operating mechanism, a dual cover interlock and a color
coded indicator handle. They are suitable for use as service equipment when equipped
with a field- or factory-installed neutral assembly or equipment grounding kit, unless a
600Y/347 V or 480 Y/277 V, 1000 A or greater, solidly grounded WYE system is used,
per NEC 230-95. Heavy duty safety switches are UL Listed (except as noted). Files
E2875 and E154828 meet or exceed the NEMA Standard KS1. For UL Listed short
circuit current ratings, see UL Listed Maximum Short Circuit Current Ratings-AC only,
page 3-11.

SAFETY SWITCHES
[1] For Rainproof Bolt-On Hubs and Watertight Hubs see Hubs, page 3-15.
[2] Complete rating is NEMA Type 3, 3R, 4, 4X, 5 and 12. For NEMA Type 3R applications, remove drain screw from bottom endwall.
[3] See 316 Grade Stainless Steel—NEMA Type 3, 3R, 4, 4X, 5, 12, page 3-12.
[4] Also suitable for NEMA Type 3R application by removing drain screw from bottom endwall.
[5] For switching dc, use two outside switching poles.
[6] For corner grounded delta systems, use switching poles for ungrounded conductors. See data bulletin 2700DB0202 for additional information.
[7] 60 ampere switch with 30 ampere fuse spacing and clips. Must use 60 A enclosure accessories including electrical interlocks.
[8] For corner grounded delta systems, use switching poles for ungrounded conductors.
[9] Suitable for NEMA Type 5 applications with drain screw installed.
