Description
WH SMICO Blade Fuse High-Rupturing Capacity HRC Low Voltage Protection Link (NT00 / NT00-C / NH2 / 63A to 400A) Industrial Switchgear Superior Safety
The SMICO Blade Fuse series provides high-rupturing capacity (HRC) low-voltage protection links engineered to safeguard commercial and industrial distribution networks from severe overcurrents and short-circuit faults.
Installed within fuse switch disconnectors, feeder pillars, and switchboard distribution panels, these fuses act as critical sacrificial defense components that safely interrupt fault currents before electrical equipment or downstream cables sustain thermal or mechanical damage.
Manufactured with high-grade ceramic bodies, silver-plated copper blade contacts, and high-purity quartz sand arc-extinguishing media, the SMICO Fuse range delivers outstanding breaking capacity up to 120kA at 500V AC.
Built in accordance with international standards including IEC 269, VDE 0636, and CE certifications, these fuses provide consistent time-current tripping characteristics and low power loss.
Key structural and functional advantages of the SMICO Blade Fuse series include:
-
High Breaking Capacity: Engineered to safely handle high-level short-circuit currents up to 120kA at 500V AC.
-
Durable Ceramic Construction: High-strength thermal ceramic housing withstands intense heat and pressure shocks during heavy fault interruptions.
-
Low Contact Resistance: Silver-plated blade contacts ensure efficient current transfer and reduced power dissipation across terminal connections.
-
Versatile Model Range: Available in standard NT00 size, compact NT00-C profile, and heavy-duty NH2 size across current ratings from 63A to 400A (Order Codes: S-NT00-63A through S-NH2-400A).
Whether deployed in main distribution switchboards, motor control centers (MCC), or outdoor utility feeder pillars, the SMICO Fuse series ensures dependable circuit protection and operating safety.

Frequently Asked Questions (FAQ)
Q1: What is the primary function of a SMICO Blade Fuse in an electrical system?
A : A SMICO Blade Fuse functions as an HRC (High-Rupturing Capacity) protective link.
It protects cables, transformers, and switchgear by melting its internal element during overloads or short circuits, interrupting up to 120kA fault currents safely.
Q2: What is the difference between standard NT00 and compact NT00-C sizes?
A : Both models fit standard Size 00 fuse bases and operate at 500V, but differs in housing dimensions:
-
NT00 (e.g., S-NT00-63A): Standard body width and length.
-
NT00-C (e.g., S-NT00-63A-C): Features a slimmer/compact ceramic body profile designed for installations with space constraints.
Q3: Can the SMICO NH2 400A fuse (S-NH2-400A) be used in 400A outdoor black boxes?
A : Yes, the NH2 / NT2 400A blade fuse is fully compatible with standard Size 2 / NH2 fuse bases, including 400A 3-pole outdoor fuse switch disconnectors and APDM 400A boxes.
Q4: What do the IEC269 and VDE0636 standards indicate?
A : These certifications confirm that SMICO blade fuses meet rigorous international standards for low-voltage fuse performance, breaking capacity, temperature limits, and electrical safety.
Q5: How do I know if a blade fuse needs to be replaced?
A : Blade fuses feature a top indicator/striker pin or window that changes state or pops up when the fuse element melts following a fault.
Once blown, the entire fuse link must be replaced with a unit of matching current rating and physical size
