Wieland Electric 57.904.6555.0 Fuse Holder Block Selos

Product Description

The WIELAND ELECTRIC 57.904.6555.0 is a fuse holder terminal block in the SELOS series, designed for modular panel wiring applications. Designated as the WK 4 THSI 6.3 LED 24U V-O configuration, this block combines fuse-holding functionality with LED status indication and a 24-volt operating reference, making it suitable for control panel builders and industrial electricians who need reliable circuit protection with visible fault indication at the terminal level. It is manufactured in Germany to Wieland quality standards and fits into the broader SELOS modular terminal block ecosystem.

This fuse holder block is intended for use in industrial control panels, machine wiring, and building automation enclosures where modular DIN-rail terminal systems are specified. The SELOS series is a professional-grade terminal block family used by panel builders, controls integrators, and licensed electricians working on low-voltage control and power distribution assemblies. Its LED indicator allows technicians to quickly identify a blown fuse without removing the block from the rail or probing with a meter.

Installation Notes

Installation should be performed by a licensed electrician familiar with IEC or NEC panel wiring standards, depending on the jurisdiction. De-energize and lock out the panel before mounting or servicing any terminal block. Verify that the fuse rating matches the circuit protection requirements before inserting the fuse element. Do not exceed the block's rated current or voltage during operation.
