Features of 300V 5×20mm Ceramic DMI Fuse
 
 

•High Breaking Capacity: Capable of safely interrupting severe fault currents within a compact 5×20mm ceramic body, providing superior protection for both sensitive instruments and users.

•Fast-Acting Performance: Instantaneous response to overcurrent conditions minimizes energy let-through, safeguarding delicate measurement circuits, precision shunts, and input protection components.

•300V AC/DC Rating: Suitable for both alternating and direct current measurement applications up to 300V, covering common industrial, automotive, and low-voltage electrical systems.

•DMI-Specialized Design: Engineered specifically for digital measuring instruments, ensuring precise and consistent tripping characteristics that do not interfere with measurement accuracy or cause nuisance blowing.

•Compact 5×20mm Form Factor: Standard miniature size compatible with most handheld multimeters, portable testers, and other space-constrained instruments.

•Ceramic Construction: Provides superior arc-quenching capability, high dielectric strength, and excellent thermal stability compared to glass fuses, reducing the risk of rupture under fault conditions.

•Wide Current Selection: Available in 250mA, 400mA, 500mA, 600mA (for low-current mA/μA inputs), and 10A (for high-current measurement ranges).
