PowerLogic P5

The PowerLogic P5 is a protective relay for more demanding medium voltage applications. It offers users dedicated features for industry-leading protection relay functionality to reduce risks, improve reliability, all with advanced connectivity. The P5 presents a major step forward for protection relays, bringing a number of best-in-class features together in one device.

• Built-in arc-flash protection functions

  Arc flash events can occur when switching or during unexpected conditions. The protection function detects if an arc-flash exists and takes action within milliseconds to isolate the connected circuit breaker.

• Advanced cybersecurity

  62443 SL1 compliant, the P5 has been designed with an advanced cybersecurity package. This means reduced exposure to cyber threats and improved operational security. Included by default are important security features such as password management, port hardening, and secured communication compliant to the latest international standards.

• Intuitive withdrawable design

  With a handle built in as part of the design, the P5 can be quickly disconnected or exchanged to speed up maintenance. Wiring, data, communication, and settings (including backup) can be stored with the panel and will be there when the relay is reconnected.

• Improved recovery time

  When maintenance or testing is required, the P5 helps dramatically decrease your outage recovery time. The backup memory can automatically restore settings, you can continue your operations in as little as 10 minutes.

• Greater connectivity

  The P5 protection relay features a wide variety of communication protocols and can support up to 3 Ethernet protocols simultaneously, including dual redundancy with PRP/HSR and RSTP protocols. All communication modules can be added at any time, including on-site, during the product life cycle to allow you to upgrade your device in line with future network evolutions.

PowerLogic P3

The P3 is a complete range of protective relays for medium voltage applications. The innovative package boasts more than 40 protection functions and a wide variety of communication protocols for enhanced connectivity and interoperability, including:

• Universal protection from a single box, with feeder, motor, and transformer protection functions

• Motor, transformer, generator differential protection

• Nine communication protocols in one box, including IEC 61850

• Embedded virtual injection testing system

• Built-in optical arc flash protection

• Programmable logic and protection stages

An example of Schneider Innovation at Every Level, the built-in virtual injection testing system enables a safer configuration process and gives you and your customers on-going peace of mind. Additionally, the P3 allows you to monitor your protection relay and circuit breaker, enabling full visibility of the health of your electrical installation.

PowerLogic A125 and A3 Arc Flash Protection

• A125 Arc Flash Protection

  Arc flash events pose serious risks to both personnel and equipment. The PowerLogic™ A125 arc flash protection offers rapid detection—within just 2 milliseconds—to help mitigate damage and enhance safety. Designed for use in low voltage (LV) and medium voltage (MV) switchgear, the A125 supports up to 4 optical point sensors, which can be strategically placed in key compartments such as cable, breaker, and bus sections. The module is set with simple DIP switches and can be set up to deliver zones of arc flash protection. Installation is easy with a DIN rail or a door mount option.

• A3 Arc Flash Protection

  The PowerLogic A3 is Schneider Electric’s next-generation arc flash protection, engineered to protect both low-voltage (LV) and medium-voltage (MV) electrical systems. Building on the proven A125 platform, the A3 delivers ultra-fast 2 milliseconds arc detection, flexible multi-panel configurations, and scalable architecture supporting up to 50 sensors and 4 to 8 control outputs. It features light point and loop sensing, current condition monitoring, and preventive maintenance sensing—all with integrated communication capabilities. A3 arc flash provides reliable operation in harsh environments and is designed for easy installation.
