Product Description

ETA 106-P30-000040-3A is a thermal circuit breaker engineered for reliable protection in low voltage circuits, particularly for applications involving motors, transformers, and power supplies. It features a 3A current rating and is designed for single-pole operation, making it suitable for compact installations on DIN rails.

The thermal tripping mechanism reacts to sustained overloads and faults, with a typical slow response time of approximately 30 seconds at double the nominal current, benefiting inductive or reactive loads. Its trip-free function ensures the circuit cannot be reset manually while an overcurrent fault persists, enhancing safety and reliability.

This breaker accommodates up to 250V AC and 48V DC systems, broadening its usability for a range of industrial and commercial environments. The button reset actuator provides easy restoration after trips, minimizing downtime while maintaining operational integrity.

Terminal connection is achieved via blade type terminals, offering secure and straightforward wiring. The compact sub-miniature construction, with double insulation and PCB/single hole mounting, supports versatile integration in control panels and equipment.

ETA's circuit breaker complies with global standards including VDE, CSA, UL, BV, DEMKO, ABS, and LROS, ensuring it meets stringent safety and quality requirements. The typical operational life is rated at 5000 operations (up to 3A) and 1000 operations (above 3A), reflecting high durability in repetitive-cycle environments.

Applications include industrial automation panels, machinery protection, laboratory instrumentation, HVAC, water treatment systems, and commercial control installations. The combination of high breaking capacity (200A), precision reset, and robust construction renders it ideal for critical circuits requiring consistent performance and fault isolation.
