What is the significance of the high rupture capacity?
The high rupture capacity allows the fuse to manage short-circuit currents effectively, protecting the downstream equipment from damage during fault conditions. This feature enhances overall system reliability and safety.
How does the gG characteristic benefit cable protection?
The gG characteristic is specifically designed to protect cables by providing a delayed response to overload conditions, preventing nuisance tripping while still offering protection against harmful fault currents.
What requirements should the fuse holder fulfil?
The selected fuse holder must be compatible with bolted tag designs, ensuring a secure connection. Ordering separately, holders like the CM100F (Camaster) are recommended for optimal performance.
What breaking capacity should I consider when using this fuse?
This fuse's breaking capacity is rated at 80kA, making it suitable for high fault current scenarios. Ensure that the chosen application environment can accommodate this specification for safety and compliance.
