Machine safety

The drives feature a built-in safe torque off (STO) function as standard which

disables the power semiconductors. As such, the drive cannot power the

motor making it torque-free. More safety functions, such as safe stop 1. safe

brake control, safely limited speed, safe speed monitor and safe direction, can

be implemented with external safety system options.

Benefits of using TIM foils in comparison to thermal grease are easier installa tion and more durable heat

transferring properties for longer periods of time. Durability par ticularly improved in a cyclic application.

The ABB FS450R12KE3/AGDR-71C is a robust and versatile automation controller designed to meet the

demanding requirements of the power industry, petrochemical sector, and general automation applications.

Known for its outstanding durability and performance metrics,

the FS450R12KE3/AGDR-71C stands out as a reliable solution for various industrial environments.

The IED offers directional and non-directional overcurrent and thermal overload protection as

well as directional and non-directional earth-fault protection. 

Some standard configurations allow as an option admittance-based, harmonics-based or wattmetric-based earth-fault protection to be

used in addition to directional earth-fault protection. 

Further, the IED features sensitive earth-fault protection, phase discontinuity protection, transient/intermittent earth-fault protection, 

overvoltage and undervoltage protection, residual overvoltage protection, positive-sequence undervoltage 

and negativesequence overvoltage protection. 

Event recording

All events are stored with a resolution of 1 ms in the central unit and in the BUs.

System, protection and test events can be generated.

Protection events refer to the protected busbar and include the changes in the disconnector and breaker positions,

trips, etc. Test events are recorded during testing with the test signal generator.

System events describe the diagnostic and fault messages of the NBP system as a whole.

Frequency protection, including overfrequency, underfrequency and frequency rate-of-change protection,

is offered in IEDs with standard configurations H and J. 

The IED also incorporates optional three-pole multi-shot auto-reclose functions for overhead line feeders.

Enhanced with optional hardware and software,the IED also features three light detection channels 

for arc fault protection of the circuit breaker, busbar and cable compartment of metalenclosed indoor switchgear.

The arc-fault protection sensor interface is available on the optional communication module.

Fast tripping increases staff safety and security and limits material damage in an arc fault situation.
