Holder Fuse
In industrial electrical systems, the Holder Fuse is the final executing unit of the fuse protection link, and its technical performance directly determines the effectiveness of the entire protection system. This product serves as a dedicated installation base for NH type knife type fuses, creating a precise electrical pathway between the busbar/cable and the fuse. During normal operation, it achieves ultra-low loss energy transmission, ensuring safe disconnection of the fuse and reliable isolation of the faulty circuit in case of a fault.

Product Introduction
Holder Fuse is a core conductive and supporting base designed for NH series knife-type fuses, and is a key basic component in industrial power distribution, equipment protection, and system safety. It uses high-purity copper as the main conductive component, undertaking four core functions of circuit conduction, fuse fixation, fault isolation, and temperature rise control. It is a key component that determines the safety, stability, energy efficiency, and lifespan of the entire distribution circuit. Contact Blade is positioned as an industrial grade high reliability electrical connection solution, aimed at engineering projects that require long-term continuous operation, high load, and high environmental requirements. It focuses on solving common pain points in the industry, such as poor contact, local overheating, high conductivity loss, vibration loosening, tedious maintenance, and short lifespan.
Specific parameters
Rated Current
The common rated current specifications for Holder Fuse include 63A, 100A, 250A, 400A, 630A, etc. Different specifications are suitable for circuits with different load currents. Users can choose the appropriate fuse holder according to their actual needs.
01
Rated Voltage
Generally available in 500V, 690V, 1000V, etc., this parameter determines the voltage range within which Fuse Copper Holders can operate safely. When using, it is necessary to ensure that the circuit voltage does not exceed its rated value.
02
Contact Resistance
High quality Fuse Copper Bases typically have a contact resistance of less than 50 μ Ω. Low contact resistance can effectively reduce heat generation and improve the efficiency and stability of electrical systems.
03
Mechanical Lifespan
After design optimization, the mechanical lifespan of Ceramic Fuse Holder can generally reach more than 5000 opening and closing cycles, which means that it can maintain good performance and reliability even under frequent operation.
04
Protection Level
Some Copper Holders for Fuse Bases have a protection level of IP20 or above, which can prevent solid foreign objects with a diameter greater than 12mm from entering and protect internal electrical connections from interference and damage from external objects.
05
Product advantages
Wide adaptability
NH Fuse Bases can adapt to various specifications of NH type fuses, meeting the protection needs of different electrical equipment and circuits, and have a wide range of applications.
01
High reliability
The sturdy structural design and stable electrical connections ensure reliable operation in various complex environments, effectively reducing the risk of electrical accidents caused by Fuse Holder for NH Fuse failures.
02
Convenient installation and maintenance
The simple opening and closing structure of Fuse Blocks Holder facilitates the installation and replacement of fuses, reducing maintenance costs and time. Clear identification also facilitates users to quickly identify and operate.
03
Long service life
High quality copper materials and surface treatment processes give it good corrosion resistance and wear resistance, extending the service life of Cartridge Type Fuse Clip, reducing replacement frequency, and lowering usage costs.
04
Customization Process
The customer provides Holder Fuse drawings in PDF/CAD/3D format - our company conducts process and price evaluation - after the price is approved, the customer places a sample order and pays 50% of the mold fee in advance - our company starts mold production - we provide free 1-20 sample express delivery to the customer for testing - after the sample passes the customer's test, the customer pays the remaining 50% of the mold fee - the customer issues a bulk order and pays 30% of the payment in advance - our company evaluates the delivery time and starts production - after the product is produced, we provide a packaging list to the customer and require the customer to pay the remaining 70% of the payment - our company delivers the goods according to the customer's specified payment.
