Product overview

SYMAP® is a flexible microprocessor-based digital protection device for use in low, medium and

high voltage power systems.

Because of its integrated protection functions and human machine interface capabilities it is an

efficient and cost-effective solution for all types of switchboards. With three powerful microproces

sors SYMAP® offers comprehensive protection functions for generators, motors (synchronous and

asynchronous), transformers, power lines and distributions.

All protection functions can be activated simultaneously. With SYMAP® five main breaker controls

can be activated with all necessary functions such as display, control and blocking for optimal

breaker manage ment. A small integrated PLC allows individual functionality, such as interlocks

from controlling functions. For flexibility in commissioning and during use, both digital and analog

outputs can be used to connect the SYMAP® control unit to main switchboard controls. Addition

ally, a variety of serial interfaces with different kinds of protocols can be used for communication

between SYMAP® units and the central control system.
