Schneider Electric NSYTRV42SF5LD Fused Terminal Block

Product Description

The SCHNEIDER ELECTRIC NSYTRV42SF5LD is a single-pole, fused DIN rail terminal block rated for 500 volts and 6.3 amps. The block is constructed from polyamide, a durable thermoplastic well suited to industrial panel environments. It accepts wire sizes from 26 AWG to 10 AWG (0.20 to 4 square millimeters), giving installers flexibility across a range of conductor gauges. The operating temperature range spans -40 degrees F to 266 degrees F, making it appropriate for both cold-storage and high-ambient electrical enclosures. Licensed electricians and panel builders install this component during control panel assembly or field wiring projects.

This terminal block is used in industrial control panels, machine wiring, and electrical distribution enclosures where fused termination at the DIN rail level is required. Its single-pole, single-row design keeps panel layouts compact. The black polyamide housing resists heat and common industrial contaminants. It is a practical choice for new panel builds and retrofit projects where per-circuit fusing at the terminal is specified or preferred by the design engineer.

Key Features

• Fused single-pole design provides per-circuit overcurrent protection directly at the terminal block
• Rated 500 volts and 6.3 amps for compatibility with standard industrial control voltages
• Accepts 26 AWG to 10 AWG conductors (0.20 to 4 square millimeters) for wiring flexibility
• Polyamide block material offers strong heat resistance across a wide temperature range
• DIN rail mounting simplifies installation and replacement in standard enclosures
• Meets CSA, UL, IEC 60216-1, VDE 0304-T21, GOST, and RoHS requirements

Compatibility

Designed for standard DIN rail installations in industrial control panels and electrical enclosures requiring fused terminal block terminations at 500 volts and 6.3 amps.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the NEC and any applicable local codes. De-energize the panel and verify zero voltage before installing or replacing terminal blocks. Confirm that conductor gauge and insulation rating are appropriate for the circuit before terminating. Do not exceed the rated voltage or amperage of the block.
