Frequently Asked Questions

Q1: What does the HR5 fuse-disconnector series include in terms of rated current options?

The HR5 fuse-disconnector series is available in four rated operational current ratings: 100A, 200A, 400A, and 630A, catering to a wide range of industrial power distribution applications.

Q2: What is the difference between signal device type "0" and "1" in the HR5 model code?

"0" indicates a non-fused signal device type, designed for use with a fuse link equipped with a fuse indicator. "1" indicates a fused signal device type, intended for use with a fuse link equipped with a tripping mechanism for automatic disconnection.

Q3: What pole configurations are available for the HR5 fuse-disconnector?

The HR5 series supports both 2-pole and 3-pole configurations, making it suitable for single-phase and three-phase electrical systems in commercial and industrial environments.

Q4: What rated operational voltages does the HR5 support, and what utilization categories apply?

The HR5 supports two rated operational voltage levels: 400V (utilization category AC-23B) and 660V (utilization category AC-22B). The AC-23B category is suitable for switching motor loads, while AC-22B covers mixed resistive and inductive loads.

Q5: What is the rated short-circuit breaking capacity of the HR5 fuse-disconnector?

The HR5 has a rated short-circuit breaking capacity with a root mean square current of 50KA and a power factor (COSΦ) of 0.25, with each switching operation performed once per cycle, ensuring reliable protection under fault conditions.

Q6: How do I determine the correct mounting dimensions for my HR5 model?

Mounting dimensions vary by model. For example, HR5-200 models have a mounting hole pitch (f) of 130mm, while HR5-630 models use 200mm. Always refer to the Outline and Installation Dimension table and diagram for precise values of dimensions a, b, c, d, e, and f corresponding to your specific model number.
