Automatic Transfer Switches

Service Entrance Rated

Model: KEP

Transfer Switch Standard Features

Enclosed Contact Power Switching Units

D Service entrance automatic transfer switches incorporate an

isolating mechanism and overcurrent protection on the utility supply,

eliminating the need to have a separate, upstream utility source

circuit breaker/disconnect switch.

D UL 1008 listed, file #58962

D IBC seismic certification available

D Fully enclosed silver alloy contacts provide high withstand rating.

D 3-cycle short circuit current withstand-tested in accordance with

UL 1008

D Completely separate utility and generator set power switching units

provide redundancy (no common parts) and are easy to service.

D Utility disconnect power switching units have overcurrent protection;

generator disconnect is available with or without overcurrent

protection:

d Molded case circuit breakers (MCCB) include thermal-magnetic

or electronic trip overcurrent protection

(80% rated).

d Molded case switches (MCSW) do not include overcurrent

protection (100% rated) (available on generator disconnect only).

d Insulated case circuit breakers (ICCB) include electronic trip

overcurrent protection (100% rated).

d Insulated case switches (ICSW) do not include overcurrent

protection (100% rated) (available on generator disconnect

only).

D Inherent stored-energy design prevents damage if manually

switched while in service.

D Heavy duty brushless gear motor and operating mechanism provide

mechanical interlocking and extreme long life with minimal

maintenance.

D Safe manual operation permits easy operation even under adverse

conditions.

D All mechanical and control devices are visible and readily

accessible.

D Padlockable service disconnect control switch

D Status indicators

D Two-position control circuit isolation switch disconnects utility power

to the transfer switch c ontroller.

D Load shed (Forced transfer from Emergency to OFF).

(Customer-supplied signal [contact closure] is required for the

forced transfer to OFF function.)

D NEMA 1, 3R, 4X and 12 enclosures are available.

Service Disco nnect Switch

D Service disconnect to OFF position

D Two-position switch with padlockable cover disconnects the normal

and emergency sources.

D Controller display shows Service Disconnected and the NOT IN

AUTO LED flashes.

D Lamp illuminates to indicate that the switch is in the DISCONNECT

position.
