Fuseholders are essential components in many electrical and electronic systems, supplying protection and reliability. The R25400-1STRM is designed to provide reliable and secure mechanical support and electrical connection for fuse links. The R25400-1STRM offers features such as snap-fit mechanical retention of fuse link, flexible design for DIN and metric size fuses, and simple push in or pull-out operation.

Application Field and Working Principle

The R25400-1STRM fuseholder is designed for both non-time delay plug-in fuse links and time delay plug-in fuse links up to 32 VDC and 10 A. It is suitable for various kinds of fuse protection, including Fast-Acting, Very Fast-Acting, and Dual-Element Fuses. The R25400-1STRM provides a secure mechanical support for the fuse terminal base, which helps maintain the stability and reduce strain on the fuse contacts. It is suitable for use in panel mounting, rail mounting, or direct mounting.

The R25400-1STRM consists of two parts: a base and a terminal base. The base is made of durable polyamide material with a highly secure snap-fit retention and the terminal base is made of sturdy polyamide material with plug-in spring support. The R25400-1STRM uses an integrated spring-locking system to secure the fuse link, and a tool-free finger-only operation to remove or insert the fuse link. This ensures that the fuse is securely retained and avoids the danger of accidental fuse connection becoming loose. The base and the terminal base are electrically connected through the press-fit contacts, which provide a reliable connection between the fuse terminal and the fuse holder.

The R25400-1STRM offers a variety of protection functions, such as over-temperature protection, current overload protection, and short-circuit protection. The over-temperature protection automatically disengages the fuse when the temperature exceeds the fuse’s rated value. The current overload protection is designed to protect the fuse holder and the connected components from current damage. The short-circuit protection in the R25400-1STRM is designed to prevent a short-circuiting, protecting the fuse holder and the connected device from damage.

The R25400-1STRM is highly reliable, cost-effective, and easy to install. The terminal base easily plugs into the fuse holder and allows for a secure mechanical and electrical connection. The terminal base also includes a grounding post which provides a reliable connection to a ground circuit in order to ensure safety. Additionally, the terminal base is designed to withstand vibration, drops, and shock without compromising the electrical connection. The R25400-1STRM can also be easily adapted to metric size fuses, allowing for easy installation and interchangeability.

In summary, the R25400-1STRM fuseholder is a reliable and cost-effective solution for fusing electrical and electronic systems. It provides secure mechanical support and electrical connection for fuse links and offers a variety of protection features such as over-temperature protection, current overload protection, and short-circuit protection. The R25400-1STRM is easy to install and is suitable for use in panel mounting, rail mounting, or direct mounting.
