RT18-32 Fuse Holder Overview
The GA&DA RT18-32 fuse holder is designed for the installation and isolation of 10x38mm cylindrical fuse links in low-voltage electrical distribution and control systems.
With a rated operational current of 32A and rated operational voltage of 400/690V AC, the RT18-32 provides a compact fuse protection solution for distribution boards, electrical control cabinets, industrial equipment and OEM electrical assemblies.
The modular design supports standard DIN rail installation, allowing installers to integrate the fuse holder into electrical panels together with other modular protection and control devices.
The RT18-32 series is available in 1P, 2P, 3P and 4P configurations, providing flexibility for different circuit layouts.
Two versions are available:
- RT18-32: Standard version without indication
- RT18-32Z: Version with indication
This makes the RT18-32 suitable for electrical distributors, panel builders, machine manufacturers, contractors and industrial buyers who require a reliable and easy-to-install cylindrical fuse holder.
Key Features of the RT18-32 Fuse Holder
32A Rated Current
The RT18-32 series supports a rated operational current of up to 32A, making it suitable for a wide range of low-voltage circuit protection applications.
Standard 10x38mm Fuse Compatibility
The holder is designed for standard 10x38mm cylindrical fuse links, one of the commonly used fuse sizes in modular low-voltage electrical systems.
Using a standardized fuse size makes fuse replacement and maintenance more convenient for installers and maintenance personnel.
Standard and Indicator Versions
Customers can select between the standard RT18-32 and the RT18-32Z indicator version according to maintenance and inspection requirements.
The indicator-equipped version makes it easier to identify fuse status during routine inspection.
DIN Rail Mounting
The RT18-32 is designed for standard DIN rail mounting, helping simplify installation inside modular distribution boards, electrical enclosures and control cabinets.
High Breaking Capacity with Fuse
When used with a suitable fuse link, the RT18-32 supports a breaking capacity of up to:
- 100kA at 500V AC
- 50kA at 690V AC
This makes the fuse holder suitable for electrical systems where dependable short-circuit and overcurrent protection is required.
