The world’s first, free to change the phase of the knife fuse switch , guard your electricity safety!
GRL Electric welcomes a new member to the DNH1 series – DNH1-□/21G(R)
DNH1-□/21G(R) fuse-type disconnect switches are mainly used in industrial control cabinets for overload and short circuit protection.
The product adopts the mounting method of hanging, can be freely adjusted phase design, can realize the fuse monitoring function, and also meets the remote monitoring function, which brings customers a safe and convenient use experience.
DNH1-□/21G(R) series are mainly available in DNH1-160/21G(R) and DNH1-250/21G(R) shells, suitable for NT00 and NT1 fuses, with rated voltages up to 690V and rated currents up to 160A-250A respectively.
The products have obtained CCC & CE certificates.
The DNH1- □/21G (R) series products bring customers three major upgrade experiences with their exquisite design and strict process flow.
Easy to install and flexible to use
The product adopts the installation of busbar hanging, free phase adjustment structure design, according to the actual use of the situation, flexible longitudinal adjustment of the phase (such as AB, AC, BC combination), convenient installation; knife fuse switch
Special fuse monitor can be assembled to realize fused signal output, real-time remote monitoring and easy management;
Optional microswitch can be installed to monitor the switch closure and disconnection status through the handle split and close operation;
Selection of materials and design
Shell material flame retardant grade V0, can be adapted to -40 ° C to +60 ° C ambient temperature, stable performance, heat-resistant and cold-resistant, to meet the extreme conditions of the operating environment;
The product adopts one-piece handle design, which is sturdy and durable and improves the mechanical life of the product; knife fuse switch
Reserved locking holes can be utilized for lead locking, preventing safety risks due to incorrect operation and eliminating the occurrence of opening and closing the gate privately; knife fuse switch
