610 serie ABB Feeder Protection REF610 Product Guide

Inputs/Outputs

• Four current transformers 

• Two digital inputs 

• Three additional digital inputs on an optional I/0 module 

• Three normally open heavy duty output contacts 

• Two change-over signal output contacts 

• Three additional signaling contacts on an optional I/O module 

• One dedicated IRF contact 

• Input/output contacts freely configurable

Communication

The protection relays are connected to the fiber-optic communication bus directly or via bus connection modules and gateways. The bus connection module converts the protection relay's electrical signals to optical signals for the communication bus and, vice versa, the communication bus' optical signals to electrical signals for the protection relay.

Mounting methods

Using the appropriate mounting accessories, the standard relay case for the 610 series relays can be flush mounted, semi-flush mounted or wall mounted. The flush mounted and wall mounted relay cases can also be mounted in a tilted position (25°) by using special accessories.

Further, the relays can be mounted in any standard 19” instrument cabinet by means of 19” mounting panels available with cut-outs for one or two relays.Alternatively, the relays can be mounted in 19” instrument cabinets by means of 4U Combiflex equipment frames.

For routine testing purposes, the relay cases can be equipped with test switches, type RTXP 18, which can be mounted side by side with the relay cases.

Mounting methods 

 • Flush mounting

 • Semi-flush mounting

 • Semi-flush mounting in a 25° angle

 • Rack mounting • Wall mounting

 • Mounting to a 19" equipment frame

 • Mounting with an RTXP 18 test switch to a 19" rack

Relay case and plug-in unit

As a safety measure, the relay cases for the current measuring protection relays are provided with automatically acting contacts for short-circuiting the CT secondaries, when a relay plug-in unit is withdrawn from the relay case. In addition, the relay case is provided with a mechanical coding system to prevent the current measuring relay plug-in units from being inserted into a case for a voltage protection relay unit and vice versa, that is the relay cases are associated to a certain type of relay plug-in unit.

There is, however, a universal relay case available, which is not associated to a certain plug-in unit type. When a relay plug-in unit is plugged into such a relay case for the first time, the relay case automatically adapts to that particular protection relay type, that is the short-circuiting contacts are activated as well as the mechanical blocking system. Hereafter, the relay case is permanently associated to a certain protection relay type.

Selection and ordering data

When ordering protection relays and/or accessories, please specify the following information: order number, HMI language set number and quantity. The order number identifies the protection relay type and hardware and is labelled on the marking strip under the lower handle of the protection relay.

Use the ordering key information in F i g u r e 7 to generate the order number when ordering complete protection relays.
