1. Product Overview
2. Core Competitive Features
✅ Standard 35mm DIN Rail Snap-On Installation
Direct buckle mounting on universal 35mm DIN rail, no extra fixing tools needed, convenient dense arrangement together with circuit breakers and other modular electrical components.
✅ Built-In Replaceable Glass Fuse Holder
Integrated transparent glass fuse cavity, easy fuse replacement without dismounting the whole terminal block, real-time visible fuse status for quick circuit fault inspection.
✅ Thickened Full Pure Copper Conductive Fittings
All conductive contact parts adopt high-purity thick brass, excellent electrical conductivity, low contact resistance, no overheating under long-time stable load operation.
✅ Anti-Slip Screw Clamping Structure
Special thread screw design effectively prevents wire slipping after long-term vibration, ensures firm wiring connection and avoids loose contact heat risk.
✅ Reinforced Anti-Break Foot Structure
Strengthened plastic base foot, anti-fracture during repeated wire disassembly and assembly, durable for long-term frequent maintenance work.
✅ V0 Grade Flame Retardant Insulation Housing
Shell made of high temperature resistant V0 flame retardant PA plastic, anti-aging, insulation safe, effectively avoid fire hazard caused by abnormal circuit temperature.
✅ Stable Electrical Rating: 690V / 20A
Standard rated parameter matches most low voltage control circuits, applicable for signal circuit, control loop and small power auxiliary circuit protection.
✅ Factory Spot Stock & Bulk Discount Support
Source factory direct sales with abundant ready stock for fast shipment; more favorable unit price for large wholesale export orders, accept OEM private logo customization.

5. Installation & Operation Guide
- Snap the UK5-HESI fuse terminal block firmly onto standard 35mm DIN rail, lock the bottom buckle to fix the terminal stably.
- Loosen the wiring screw, insert stripped copper wire into the wiring cavity, tighten the anti-slip screw to clamp wire tightly without slipping.
- Open the red top fuse cover, put matched 20A glass fuse into the internal holder, close the cover to complete fuse installation.
- Connect power supply and load circuit respectively on two sides of the terminal block, the fuse will blow automatically to cut off circuit when overload or short circuit happens.
- After fault troubleshooting, open the top cover and replace the blown fuse to restore normal circuit operation.
