Build in the protection and security you need

The COMBIFLEX mounting and engineering system

is a complete concept for engineering of relay and

control panels. Based upon this concept, complete

panels can easily be built.

COMBIFLEX components can provide simple custom

logic circuits via auxiliary relays, timers and standard

functions.

Measuring relays e. g. for currents and voltage

provide simple and fast system solutions. In addition,

some of the special measuring relays available offer

characteristics not available with standard protection

terminals.

All our products, however, have the advantage of

being designed and developed specifically for integra-

tion with the COMBIFLEX mounting and engineering

system. The COMBIFLEX system offers several

advantages.

Flexibility

Standard mechanical dimensions and connection

patterns. Availibility of all standard relay functions.

Comfort

Connections are based on terminal pins and sockets

with ready made conductors.

Simple transfer connection

Two conductors can be connected to virtually all

electrical points, making connection simplicity itself.

Personal safety

All connection point are insulated for human

contact and all routine tests can be made while

system is in service and energized, and without

changing any connections.

COMBIFLEX products

The revitalised range covers a wide spectrum of

products from measuring relays and time, auxiliary

and bistable relays to relay assemblies dimensioned to

meet forthcoming engineering requirements in power

systems and industrial applications. The full range of

new relays is presented on the pages 5-7 of this

brochure, and the range of available relays is shown

in the Byuers Guide catalogue.

Combitest relay test system

Even though modern microprocessor equipment has

built-in self-test and monitoring functions, it can be

necessary to use an injection test facility. This ensures

that all parts of the final assembly and overall system

work exactly as intended. The secondary injection testfacility can also be used to enable the relay system to

receive a simulated or recorded power system event

in play-back mode. This permits testing of cases

which may have caused confusion or concern in relay

operation or lack of operation. Numerical play-back is

further facilitated using test system simulation software.

be used stand alone in the form of measuring relays

for different applications, separate logic circuits as

well as comprehensive protective assemblies for a

variety of protection purposes. COMBIFLEX is also

compatible with components used for testing,

connection and designation purposes.

A part of the ABB SA Concept

The COMBIFLEX system is built for the future: new

technology provides new and additional functionality

and complements the other microprocessor protective

relay and control equipment families, for example the

500-series. The COMBIFLEX system is an integrated

part of the overall ABB SA concept for integrated IT-

solutions for the power industry. The reliability of the

COMBIFLEX system is documented through 25 years

of use in many different environments, including

nuclear power applications.

COMBIFLEX environment

The 500-series represents terminals for line distance,

differential, transformer protection as well as bay

lever control. These protection terminals are often

integrated with separate relays for backup measurement,

trip functions or contact replication. The terminals

combine easily with COMBIFLEX auxiliary equipment

such as test switches, auxiliary tripping relays, lock-out

relays and other units in the design of complete

protection and control cubicles.

The COMBIFLEX range covers products which may

Mounting and Engineering System with

overall coordination and integration

With the introduction of the 500-series protection, monitoring

and control equipment, each protection system offers a wide

range of internal flexibility. By utilising various combinations of

additional COMBIFLEX modular options the same basic

product can be used in a wide variety of applications, mountedin 19" racks, panels or walls.

The RAHx/RXHx 4xx-series of numerical products are

intended for general power system applications and as

back-up to 500-series terminals for all system voltage

levels including EHV. The relays are also suitable for

retrofit of installations using static or electromechanical

designs. Several mounting alternatives are available;

19" racks, panel mounting cases and DIN-rail adapters.

Ease of handling is an added benefit as well as the

easy integration with all other relays and test switches

of COMBIFLEX design.

Connection system

The COMBIFLEX connection system has been used over many decades and

has shown itself as a very reliable system, combining flexibility with installation

convenience. It is used for wiring panels and rack-mounting assemblies which

require dual snap-in terminals for each electrical point. Moreover, the terminals

are insulated from human contact, enhancing personnel safety. Safety is further

improved by the fact that all the terminals are locked in place. This connection system

lends itself to CAD-design as a tool when creating new relay and control systems.

Designation system

The COMBIFLEX designation system is part of the invisible mounting

and engineering system which nobody sees in everyday work but

which would be immediately noticeable if it was missing. Thedesignation system is the backbone of the process as it covers the

entire chain from marking of relays and other components on the

drawings to defining their connection points in circuit diagrams and

connection tables. This system facilitates computer aided design.

Mounting system

The COMBIFLEX mounting system for relay equipment has been shaped over

decades of practical experience from assembly of complete relay and control systems.

The system is based on the 19" rack standard which permits simple combinationof products using the same international standard. It offers various ways of building

up the relay and control panels. All the minor details of COMBIFLEX integrate

perfectly and form well-functioning panel designs.

New Panel Maounting Cases RGHP

The new RGHP panel mounting cases enables affordable cut out mounting of

indiviual COMBIFLEX modules in panels. Test switches, powersupplies, auxilary

relays and measuring relays of all types may thus be flush panel mounted. Anyrelay type of COMBIFLEX design can thus be mounted and used in existing

panels. Mounting in typical switch-board panel cut-outs is more affordable with

the new RHGP panel mounting cases.

New Retrofit Case for 900-series

A version of the size new case RHGP 4B is intended for mounting in the same cut out

space as the earlier 900-series relays made by ABB in Switzerland, e.g. the current

relays type IKC 9xx, IKT9xx, the voltage relays type UKT9xx and the Rxx9xx-series

etc. This is introduced to facilitate retrofit and extensions of earlier installations.
