What is Not Supported in the E300 Relay?
The Bulletin 857 relay is a feature rich product which provided control and protection solutions to a wide global array of applications. The
E300 relay is not as feature rich and thus does not directly replace all of the capabilities of the Bulletin 857 relay for all applications. Review
the tables below to consider the comparable protection and control capabilities of the E300 relay. Compare the basic functionality,
protective elements capabilities, and your application requirements to determine if the E300 relay is a suitable migration option. The

Physical Variances Between the Relays
There are very specific differences in the physical attributes between the Bulletin 857 and the E300. There presently is no retrofit hardware
kit to support this migration. Customers need to review their physical installations and determine a suitable path forward for migration from
the Bulletin 857 products, in the case of replacement of installed Bulletin 857 products. Included in the sections below are both the physical
and wiring variances between the two products. The Bulletin 857 is a single base relay with one external RTD scanner option which is
interconnected to the base relay by way of either a single or dual fiber optic interface. The E300 product is utilizes a modular approach
where individual component modular are interfaced by way of a Controller Area Network (CAN bus) communications network.
Mechanical Considerations to Replace a Bulletin 857 Relay
The E300 overload system can be used in place of the Bulletin 857 for many applications. You must review their specific application
requirements and the protective elements used in the Bulletin 857 to determine if the E300 is an appropriate substitution. The E300 cannot
perform all the functions of the Bulletin 857 can perform. However, the E300 does provide basic motor protection functionality, diagnostic
and networking capabilities for many applications.
The E300 is a modular style of system which requires multiple modules to perform different functions. Shown below are aspects of the
typical hardware module configurations which are used to configure systems of varying capabilities. These configurations facilitate the use
of primary current transformers with five ampere secondaries. The E300 does require a very specific zero sequence ground fault current
transformer, specifically the Bulletin 193-CBCTx. The typical 100:1 ratio ground fault current transformer, used with the Bulletin 857, cannot
be used in place of the required 193-CBCT3 or 193-CBCT4.
One of the more significant details regarding the physical characteristics of the E300 is that it is a module component system where the
components are either directly panel mounted or mounted on a DIN rail also affixed to a panel, unlike the Bulletin 857 which is a door
mounted device.
When considering a migration path to the E300, the door cutout used for the mounting of the Bulletin 857 must be covered. One option is the
utilization of the space on this cover plate to mount the E300 components. The E300 components can easily fit on the rear of the cover plate
used to cover the cutout used for the Bulletin 857. Additional space would not then be required on the panel. Since the control and analog
wiring is already routed to this area, making the associated electrical connections is also easily facilitated.

E300 Relay Mounting Location
Since the E300 is a modular style of system, where the individual modules can easily be mounted using a DIN rail, multiple modules could be
mounted on the filler plate used to cover the hole from where a Bulletin 857 was removed. Shown below is one example of a typical hardware
retrofit solution.
When considering a migration path to the E300, the filler plate used for the door cutout, used to cover the mounting hole for the Bulletin 857,
can be utilized as a mounting location for the E300 modular components. Utilizing this space permits a simple physical installation of the
E300 components. Additional space would not then be required on the control panel. Since the control and analog wiring is already routed to
this area, making the associated electrical connections is also easily facilitated without the requirement of redressing or rerouting the wire
harness bundles.
Alternatively, the E300 components could be mounted on the control panel space if there is physical space to mount the components.
Because each module is interconnected to the next, the components do not have to be located side by side.

Frequently Answers and Questions

What is the purpose of the Allen-Bradley 857 Protection Relay to E300 Electronic Overload Relay Migration Guide?

This guide assists customers in migrating from the discontinued Bulletin 857 relay to the E300 electronic overload relay. It provides information on selecting appropriate E300 components and adapting wiring configurations for a smooth transition.

Does the E300 relay offer the same functionality as the Bulletin 857 relay?

The E300 relay does not directly replace all the capabilities of the Bulletin 857 relay. It offers basic motor protection functionality, diagnostic features, and networking capabilities. Refer to the 'Comparison of Primary Protection Elements and Capabilities' section in the viewed document for a detailed comparison.

What are the physical differences between the Bulletin 857 and E300 relays?

The Bulletin 857 relay is a single base unit with an optional external RTD scanner, while the E300 relay uses a modular approach with individual components connected via a CAN bus network. The E300 is panel mounted or DIN rail mounted, while the Bulletin 857 is a door mounted device. The E300 also requires specific zero sequence current transformers (193-CBCTx) unlike the Bulletin 857.
