HNXD63B100

The Siemens HNXD63B100 circuit breaker serves as a robust solution within electrical distribution systems. It is a low voltage molded case circuit breaker with an impressive current rating of 1000 A and is designed to operate at a voltage of 480 VAC. With three poles, this device effectively manages 3-phase power applications.

The trip unit is thermal-magnetic, which means it provides reliable overload protection, responding to both moderate and severe fault conditions. The interrupting capacity stands at 65 kA, ensuring that the circuit breaker can handle significant short-circuit currents without sustaining damage. It operates effectively within a frequency range of 50 to 60 Hz, making it versatile across different electrical systems. Additionally, the trip range is adjustable, facilitating operation from 5000 to 10000 A, which enhances its ability to protect against a wide range of fault scenarios.

For installation, this circuit breaker utilizes a bolt-on connection type, which ensures a secure fit within a panel. It is suitable for wire sizes ranging from 250 to 500 kcmil, providing flexibility for substantial wiring arrangements. The HNXD63B100 also operates in ambient temperatures of up to 40 °C, making it capable of performing in a variety of environmental conditions. Furthermore, this model is RoHS compliant, reflecting Siemens’ commitment to environmentally responsible manufacturing practices.
