A fuse holder, also known as a fuse base, provides the mechanical mounting and electrical connection for a fuse-link. The holder must securely retain the fuse-link, provide low-resistance contact between the fuse-link end-caps and the circuit conductors, and contain arc energy during operation. The UKRT18 series cylindrical fuse holders support 10x38mm, 14x51mm, and 22x58mm fuse-links with rated insulation voltages up to 690V and conventional thermal currents up to 125A. These fuse holders support various fuse types (gG, aM, aR) per IEC 60269 standards, featuring a built-in fuse status indicator light and a 100kA short-circuit stability rating. Configured in multi-phase combinations, they provide the function of power isolation, featuring a secure 35mm DIN rail mounting structure for residential, commercial, and industrial distribution boards. This selection guide covers fuse holder type, rated current, fuse-link compatibility, and switching capability.
UKRT18 Fuse Holder Series Technical Specifications
Fuse Holder Type Selection by Application
Cylindrical fuse holders—specifically the UKRT18 series in 10x38mm, 14x51mm, and 22x58mm sizes covering 32A, 63A, and 125A—are used in residential, commercial, and industrial distribution boards, where their compact form factor fits onto a standard 35mm DIN rail. These fuse supports are designed for AC 50Hz systems with a rated insulation voltage up to 690V. The fuse holder must be rated for the same or higher current and voltage as the fuse-link it will contain.
UKRT18 Fuse Holder Isolation and Status Indication
The UKRT18 series fuse holders provide the function of isolating the power supply when configured in multi-phase combinations. Each unit is equipped with a built-in fuse indicator light that signals immediately when a fuse-link has blown. Constructed from high-quality, heat-resistant molded plastic shells with contact and fuse carrier components, these supports are built for reliable performance in standard electrical environments.
Fuse-Link Compatibility and Utilization Categories
The UKRT18 series supports various fuse-link types (such as gG, aM, aR, etc.) per IEC 60269 standards, providing strong adaptability for different load circuits like lighting and power distribution. gG fuse-links provide general-purpose protection, while aM and other specialized categories match specific industrial and equipment protection requirements within the specified current parameters.
Breaking Capacity and Short-Circuit Stability
UKRT18 series fuse holders have the ability to withstand conventional thermal currents and expected short-circuit impact currents up to 100kA dynamic and thermal stability.
