Standard; Economy; Temperature Rise In Case Of Modules >13 A; Pxs24 With Supply Terminals - Eaton PXS24 Series Technical Manual

Technical manual MD019003EN
Valid as of September 2020

2.3 Standard

The Standard version of the PXS24 module offers the perfect combination of protection and connectivity.
All Standard modules are equipped with a communication interface.
The Standard modules are available with a fixed rated current of up to 16 A.
The communication interface offers the following advantages:
• Sequence control (see "Communication interface – Sequence control")
• Digital outputs (see "Communication interface – Outputs")
• Digital inputs (see "Communication interface – Inputs")
•
The option to use the device as a protective relay (see "Applications – Using the PXS24 as a protective
relay")

2.4 Economy

The devices of the Economy series do not have a communication interface. They are designed for applications where
no circuit-breaker status messages are required.
2.5 Temperature rise in case of modules >13 A
In order to protect the individual modules from the thermal effects of the adjacent modules, we recommend placing
a module with a rated current >13 A next to a module with a rated current <13 A wherever possible.
Derating: If three or more modules rated 16 A are placed directly next to each other (in the specified temperature
range), these must be derated to 13 A.

2.6 PXS24 with supply terminals

Active modules with the additional designation "IT" are equipped with feed-in terminals and can thus supply power
to the busbar. A maximum current of 20 A may be supplied per module.
Modules without the additional designation "IT" are not equipped with feed-in terminals and can therefore only be
supplied via the busbar.
