1. Product Overview
RT36-00 NH00 knife blade fuse belongs to NH series low voltage fuses, also known as knife contact fuse. It is widely adopted in low-voltage AC and DC power distribution systems to offer reliable overload and short-circuit protection for electrical equipment.
The complete assembly consists of NH00 ceramic fuse link and supporting fuse holder. The fuse body uses high-strength explosion-proof ceramic material; knife contact is made of thick pure copper to ensure low contact resistance and stable power transmission. This product strictly complies with GB/T 13889.2 and HD 60269-2 international standards. It works stably in industrial distribution cabinets, motor control equipment, photovoltaic combiner boxes and other scenarios. As a professional electrical manufacturer, we maintain full stock of all current specifications and support bulk export orders.
2. Core Competitive Features
✅ High Breaking Capacity
AC500V breaking capacity up to 120kA, effectively block short-circuit current and protect circuit devices.
✅ Wide Rated Voltage Range
Suitable for AC690V alternating current and DC290V direct current circuits, applicable for photovoltaic DC side protection.
✅ Explosion-Proof Ceramic Housing
High temperature resistant ceramic shell effectively prevent arc splash when fusing, improve operation safety.
✅ Pure Copper Knife Blade Contacts
Low contact resistance, less heat generation, stable conductivity under continuous full-load working condition.
✅ Multiple Current Specifications Optional
Available ratings:16A,32A,63A,100A,125A,160A,200A,250A,315A,400A,500A,630A to satisfy various load requirements.
✅ Flexible Installation Method
Support surface mounting; DIN rail mounting optional with matched base, easy to install inside electrical cabinets.
✅ Standard Universal Size
Standard NH00 dimension, interchangeable with mainstream NH00 fuse in global market.
✅ Separate & Complete Set Supply
Customers can purchase fuse link individually or complete assembly (fuse link + fuse holder).
