Non-fusible switches

The UL listed short-circuit

ratings for Eaton non-fusible

switches are based on the

switches being properly pro-

tected by overcurrent protective

devices. For applications that

require a UL listed short-circuit

rating of 10,000 rms symmetrical

amperes or less, an Eaton non-

fusible switch must be properly

protected by any overcurrent

protective device rated no greater

than the ampere rating of the

switch. For applications that

require a UL listed short-circuit

rating of greater than 10,000

rms symmetrical amperes, an

Eaton non-fusible switch must

be properly protected by the

appropriate class and size fusing

noted on the switch publication.

Otherwise, this non-fusible

switch must be replaced with

an Eaton fusible switch that uses

the appropriate fusing required.

Safety switch short circuit rat-

ings are applicable to AC only.

Safety switch I2t and Ip values

are identical to UL maximum

acceptable I2t and Ip values for

the corresponding class fuse.

Renewal parts

Replacement parts for a specific

catalog number are shown on

the inside door label (publica-

tion) of the switch. Switch

bases, fuse bases, line shields

(fusible switches) and operating

handles (400A and above) are

typically available as applicable.

For additional information,

refer to Renewal Parts Catalog

RP00801001E.
