Key Features
-
Time-delay design tolerates short inrush currents (such as those from transformers or solenoids) without blowing prematurely.
-
Current-limiting behavior reduces damage caused by heating and magnetic effects during a short-circuit event.
-
High interrupt rating (200 kA at 600 V AC) ensures robust protection in fault-intensive environments.
-
Class CC rejection-style end caps prevent improper substitution of lower-rated fuses, supporting code-compliance and system safety.
-
Compact cartridge size (10 × 38 mm approx) allows installation in tight panel spaces while maintaining high performance.
