4 125A Datasheet

The 4 125A Datasheet is a critical document for anyone working with electrical systems that require robust circuit protection. It provides detailed specifications and performance characteristics for 125A circuit breakers, devices designed to protect electrical circuits from overcurrent and short circuits. Understanding the 4 125A Datasheet is essential for selecting the right circuit breaker for a specific application, ensuring safety, and preventing equipment damage.

Decoding the 4 125A Datasheet Essentials

The 4 125A Datasheet contains a wealth of information about a 125A circuit breaker, but some key parameters are particularly important. These parameters define the breaker’s operating characteristics and suitability for various applications. Crucially, understanding these parameters allows engineers and technicians to make informed decisions about circuit protection. Properly interpreting the datasheet ensures that the selected breaker will reliably interrupt fault currents and prevent catastrophic failures. The following provides a simplified overview:

• Rated Current (In): This is the maximum continuous current the breaker can carry without tripping under specified conditions. For a 125A breaker, this value is 125 Amperes.
• Breaking Capacity (Icu/Ics): This indicates the maximum fault current the breaker can safely interrupt without being damaged. Icu is the ultimate breaking capacity, while Ics is the service breaking capacity (the breaker can interrupt this current multiple times).
• Voltage Rating (Ue): This specifies the maximum system voltage the breaker is designed to operate within safely.

Datasheets also detail the breaker’s trip curve, which describes the time it takes for the breaker to trip under different overload conditions. Different trip curves (e.g., B, C, D) are designed for different types of loads. A Type B curve might be suitable for resistive loads, while a Type D curve is better suited for inductive loads like motors. Furthermore, the datasheet provides information on operating temperature, environmental ratings (IP ratings for dust and water protection), and compliance with relevant safety standards (e.g., IEC, UL). Below is a short list about the trip curve types:

1. Type B: Trips at 3-5 times the rated current.
2. Type C: Trips at 5-10 times the rated current.
3. Type D: Trips at 10-20 times the rated current.

Finally, the 4 125A Datasheet includes physical dimensions, wiring diagrams, and installation instructions. This information is crucial for ensuring proper installation and integration of the circuit breaker into the electrical system. The below sample table represents the environmental information about the 4 125A circuit breaker.
