AQ 200 & 300 Series Protection Relays
AQ 200 & 300 Series Protection Relays
AQ 210 and AQ 250 – Protection relays for the most demanding applications
Both AQ 210 and AQ 250 series provide optimal solutions for any electrical protection and control application, from utilities and power plants to wind power and heavy industry applications (offshore, marine) as well as industrial and institutional electrical systems. The series offer both integrated and segregated protection control, monitoring, and measuring solutions that include complementary and powerful monitoring, measuring, communication, and diagnostics information.
The AQ 250 series has many advantages: it offers a large full-color display that you can configure yourself, and is equipped with up to 14 expansion slots for option cards (compared to the six in AQ 200). AQ 250 is therefore ideal for applications that require a more integrated functionality.
All our protection relays are easy and fast to configure which reduces engineering costs, while the devices’ unique modularity reduces the lifecycle costs of your installation. The latest technologies give protection and control engineers new options and open a whole new dimension of protection and control!
The AQ 210 and AQ 250 series provide…
- complete line, feeder, capacitor bank, transformer, generator, and motor protection applications.
- the perfect choice for the most demanding protection applications (including rotating machines).
- a future-proof solution for distributed protection and control.

AQ 300 – Protection relays for high-performance protection
The AQ 300 protection relay series combine a powerful and modern design with decades of proven relay protection history. The series provides a long-term technology solution for all transmission protection and control applications, extending to sub-transmission and distribution levels.
We offer a complete selection of line distance and differential protection, distributed and centralized busbar protections, and multi-winding transformer protection. Additionally, comprehensive generator protections and bay control units are available.
The AQ 300 series provides…
- a full range of solutions for any high-performance protection application, especially for transmission.
- high scalability with both standard and customized configurations, as well as additional I/O slots.
- an intuitive HMI, a high recording capacity, and an integrated WEB server feature.
