OVER CURRENT PROTECTION
Thomson Power Systems TS 870
series of Automatic Transfer Switches may be supplied with or
without integral over current protection as described below:
6.1.
STANDARD TS 870 AUTOMATIC TRANSFER SWITCH
The standard TS 870 Automatic Transfer Switch does not contain any integral over current
protection and requires upstream over current protection devices for both Utility and Generator
sources. The Standard TS 870 can withstand a maximum short circuit fault current as noted
in
SECTION 16
of this manual. The standard TS 870 transfer switch model without integral
over current protection is identified in the product model code. Refer to
SECTION 4.3
of this
manual for further details on model coding
.
6.2.
OPTIONAL TS 870 AUTOMATIC TRANSFER SWITCH WITH INTEGRAL
OVER CURRENT PROTECTION
TS 870 transfer switches will have integral over current protection supplied on the Utility source
as standard. The type of over current protection utilized is dependent upon ATS amperage
size and optional features specified. For transfer switches rated 100A through 200A, over
current protection is non-adjustable thermal-magnetic type trip units. For transfer switches
rated 250A through 1200A over current protection is adjustable electronic type with long time
& instantaneous trip unit elements with optional ground fault protection elements.
NOTE:
Ground fault protection is supplied as standard on 1000A and 1200A transfer switches
that are used on systems greater than 240V.
An upstream over current protection device is required on the generator source which feeds
the TS 870 Transfer Switch if integral over current protection option is not specified on the
ATS.
NOTE:
For models of transfer switch with adjustable integral over current protection trip units,
the over current protection must be set prior to operation. The equipment will be shipped from
the factory with a long-time current setting of 100% (of the equipment rating) and maximum
instantaneous/short-time current and time delay settings.
WARNING
Do Not Energize this equipment until
device settings have been verified to
ensure proper system protection &
coordination. Failure to do so may result
in equipment failure.
Refer to
SECTION 4.3
Product Model Code for types of integral over current protection which
are supplied with the transfer switch.
