IDS - Model ACOS 300 - Protection Devices
Short circuits and earth faults do not only lead to grid outages and, consequently, incalculable risks, but also cause damage to switchgear and, in the worst of cases, to persons. More than ever, efficient solutions for protection and control are required to meet these and other challenges that have arisen from the injection of renewable energies into the power grids. The ACOS 300 protection devices from IDS offers reliable protection for medium- and high-voltage grids and installations, including their operation and monitoring.
Benefits of ACOS 300
- A complete portfolio of protection functions, combined with new functions for decentralised energy production networks (QU protection, automatic under-frequency load shedding))
- Compact protection and bay control devices for all sorts of tasks
- Fast adaptations to changing market requirements
- Modular structure: all devices are based on a uniform hard- and software, thereby reducing service and maintenance costs
- Uniform engineering workflow
- User-friendly and targeted operating concept
- Flexible solutions for secondary equipment in existing installations
Types of Protection Devices
The ACOS 330 Series
The ACOS 330 series features small-size and compact protection devices that are economical and can be universally used, which makes them ideal for concepts where the focus is on protection functions.

- ACOS 333 Directional overcurrent protection
- ACOS 334 Distance protection
- ACOS 335 Line differential protection
- ACOS 338 Voltage/frequency protection
The ACOS 350 / 390 Series - Compact Protection Devices
The ACOS 350/390 series features modular, scalable and versatile protection devices for individual applications. These compact protection devices are suitable for new installations and for automation tasks in modern switchgear, in any type of environment.
- ACOS 351 Non-directional overcurrent time protection
- ACOS 353 Directional overcurrent protection

- ACOS 395 Transformer differential protection (three-winding transformers)
Protection Functions for all Applications
The multifunctional protection devices from IDS feature a wide range of protection function blocks (LINK protection function matrix) which enable the implementation of extensive protection concepts. These blocks are based on primary protection functions which, in part, are able to operate directionally.
- Overcurrent protection
- Earth fault protection
- Distance protection
- Differential protection
- Motor protection
- Transformer protection
Supplementary Functions for “New“ Smart Grids
Rapid changes in power grids require independent protection elements. Thanks to certified protection blocks in our devices, IDS is able to fulfil the respective market requirements.
- Reactive power-undervoltage protection (QU protection)
- Automatic under-frequency load shedding (UFLS protection)
