In machine building, downtime isn’t an option—and legacy thermal-magnetic breakers can't meet the speed, precision, or data visibility required in today’s control environments. E-T-A’s electronic circuit protection devices are engineered to align with IEC 60204-1, UL508A, and NFPA 79 requirements, helping you build smarter, more reliable machines.

Designed for 24VDC industrial control circuits, our electronic protectors enable selective channel-level shutdown, real-time fault diagnostics, and reduced integration complexity—empowering engineers to build safer, more efficient automation systems.

Precision Protection in Control Circuits | Faster Fault Isolation. Higher System Availability.

Millisecond-Level Response Times

Detect and disconnect overload or short circuit conditions faster than mechanical devices—protecting sensors, actuators, and PLC Iz/O modules.

Selective Load Disconnection

Only the affected channel is tripped—adjacent circuits remain powered and functional, reducing system recovery time and isolating fault zones.

Enhanced Diagnostics & Remote Reset

Local and remote status indication via digital output or IO-Link allows engineers to immediately identify the cause of trip events and restore function without manual intervention.

Ideal for distributed I/O architectures and safety-rated systems where uptime and data transparency are essential.. Want to learn more? Read the article "Improve Plant Production by Addressing 24 VDC Switch-Mode Power Supply Issues"

Simplified NEC Class 2 Circuit Design | Compliant Power Distribution Without Class 2-Rated Power Supplies

Use Standard 24VDC Power Supplies

Replace expensive Class 2 SMPS units—our devices limit output current at the load, ensuring power-limited circuit compliance.

Save on Conductor Sizing and Enclosure Space

Class 2 circuits can use reduced gauge wiring and simplified routing inside the panel or field enclosure.

Streamline UL508A Panel Certification

UL-listed Class 2 electronic circuit protectors simplify documentation, testing, and inspection processes.

Compatible with power busbars and modular DIN rail systems to support fast panel assembly and flexible expansion. Want to learn more? Check out the application note  "The Benefits of Electronic Circuit Protectors in NEC Class 2 Circuits"

Built for Industry 4.0 and Predictive Maintenance | High Transparency. Compact Design. No Extra Hardware.

Live Channel-Level Data

Replace expensive Class 2 SMPS units—our devices limit output current at the load, ensuring power-limited circuit compliance.

Compact 12.5 mm Footprint

Dual-channel modules reduce space in high-density enclosures—ideal for decentralized field junction boxes or cabinet-mounted control systems.

Tool-Free Configuration

Push-in connections and busbar mounting eliminate the need for terminal blocks or jumper accessories.

Enables decentralized control architectures aligned with modular machine design principles and the NAMUR Open Architecture (NOA) model. Want to learn more? Read the article  "Increase System Uptime with Intelligent Condition-based Monitoring Solutions & Planned Maintenance"
