The R29-23250-1, manufactured by Sensata Technologies/Airpax, is a hydraulic-magnetic circuit breaker. These breakers are designed to provide reliable circuit protection by responding to overcurrent conditions while remaining unaffected by ambient temperature variations, unlike thermal circuit breakers. This makes them suitable for applications where stable and predictable performance is crucial.

Applications

• Power Supplies: Protecting power supplies from overcurrent conditions.
• Marine Applications: Providing circuit protection in boats and other marine vessels.
• Generators: Protecting generators from overload.
• HVAC Systems: Providing circuit protection in heating, ventilation, and air conditioning systems.
• Industrial Equipment: Protecting sensitive electronic equipment in industrial environments.

Features

• Hydraulic-Magnetic Technology: Provides trip characteristics that are independent of ambient temperature.
• Accurate Trip Point: Offers a precise and repeatable trip point for reliable overcurrent protection.
• Variety of Current Ratings: Available in a wide range of current ratings to suit different applications.
• Voltage Ratings: Suitable for both AC and DC voltage applications.
• Reset Mechanism: Features a manual reset mechanism to restore circuit operation after a trip.

Benefits

• Reliable Circuit Protection: Provides reliable and accurate protection against overcurrent conditions.
• Temperature Independent: Performance is not affected by changes in ambient temperature.
• Long Service Life: Designed for long-term reliability and minimal maintenance.
• Safe Operation: Protects equipment and personnel from electrical hazards.
• Versatile Applications: Suitable for a wide range of applications due to its robust design and stable performance.

Additional Details

The R29-23250-1 circuit breaker's trip time curve depends on the magnitude of the overcurrent. It is typically designed to trip quickly under severe fault conditions and more slowly under minor overloads. The specific interrupting capacity, voltage rating, and current rating for this model are critical parameters and must be verified in the Airpax datasheet. Installation should be performed by qualified personnel in accordance with applicable electrical codes and standards.
