Schneider Electric NSYTRV42SF5LA Fused Terminal Block

Product Description

The SCHNEIDER ELECTRIC NSYTRV42SF5LA is a single-pole, fused DIN rail mount terminal block rated for 500 volts and 6.3 amps. Built from black polyamide, it provides reliable fused circuit protection within control panels, distribution boards, and industrial enclosures. The block accepts wire sizes from 26 AWG to 10 AWG (0.20 to 4 sq mm), giving electricians flexibility across a range of conductor sizes. With a temperature range of -40 to 266 degrees F, it holds up in demanding thermal environments. Three contacts per block support standard wiring configurations for fused termination applications. Licensed electricians and panel builders are the primary installers for this component.

This fused terminal block is suited for use in industrial control panels, machine wiring, and building automation enclosures. Its DIN rail mounting design allows for fast, tool-free rail assembly alongside other terminal blocks and components. The polyamide housing meets multiple international standards, making it appropriate for commercial and industrial projects that require certified components. Compatible wire sizes span a wide AWG range, accommodating both fine-stranded control wiring and heavier conductors in a single block design.

Compatibility

Designed as an OEM-style DIN rail fused terminal block for use in standard 35mm DIN rail control panel assemblies requiring single-pole fused termination.

Installation Notes

Installation should be performed by a licensed electrician following applicable NEC requirements for control panel wiring. De-energize the panel and verify the circuit is locked out before installing or servicing terminal blocks. Snap the block onto the DIN rail and ensure it seats fully before terminating conductors. Do not exceed the rated voltage or amperage of 500 volts and 6.3 amps for any connected circuit.
