Wieland Electric 57.904.6755.0 Fused Terminal Block 250V 10A

Product Description

The WIELAND ELECTRIC 57.904.6755.0 is a fused terminal block designed for single-tier, single-circuit wiring applications in industrial and commercial electrical panels. Part of the Selos Series, it accepts a 1/4 inch x 1-1/4 inch fuse and handles wire ranging from 22 to 10 AWG with screw connection terminals. Rated at 250 volts and 10 amps, this block suits low-voltage control circuits found in HVAC equipment, automation panels, and building systems. The thermoplastic housing is gray and mounts directly to standard DIN rail or G-profile rail. Electricians and controls technicians install this block during panel builds or service upgrades where fused protection at the terminal point is required.

This fused terminal block fits single-tier DIN rail panel layouts in both residential and light commercial applications. It is commonly installed in HVAC control panels, motor control centers, and industrial enclosures where individual circuit fusing at the terminal is specified. The screw connection contact style allows solid and fine-stranded conductors to be terminated cleanly within the stated wire range. The block width of 0.24 inches (6 mm) allows dense component spacing on the rail.

Key Features

• Accepts 1/4 inch x 1-1/4 inch fuse for individual circuit protection at the terminal point
• Rated 250 volts and 10 amps for low-voltage control circuit applications
• Wire range 22-10 AWG accommodates both solid and fine-stranded conductors via screw connection
• Mounts on standard DIN rail or G-profile rail for quick panel installation
• Thermoplastic gray housing with a block width of 6 mm (0.24 inches) for dense rail spacing
• Part of the Wieland Selos Series for consistent modular panel design

Compatibility

Designed for use in standard DIN rail panel assemblies as a single-tier, single-circuit fused terminal block. Compatible with DIN rail and G-profile rail mounting systems. Model type WK 4/THSI6,3 GL 250U/V0.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize the panel and verify zero voltage at all conductors before installing or replacing terminal blocks. Ensure conductor cross-section falls within the stated range of 0.5 to 6 sq-mm solid or 0.5 to 4 sq-mm fine-stranded before terminating. Install the correct 1/4 inch x 1-1/4 inch fuse rating for the circuit load before energizing.
