Schneider Electric Series DF Rail Mount Fuse Holder, 50A Current, 690V Voltage - DF143NC
This rail-mount fuseholder is designed to carry 14x51mm tubular fuses and to be installed on a 35mm DIN rail in industrial control and power distribution panels. It provides a compact, rail-mounted solution for three-phase Plus NEUTRAL arrangements at voltages up to 690V and is intended for use where clear fuse indication and straightforward switching are required.
Features & Benefits
• 50A rated operational current for high-load circuit protection
• Indicator fitted to show fuse status at a glance
• Screw-clamp terminals supporting up to 25mm² for secure connections
• Withstands 8 kV impulse voltage for transient resilience
• Short-circuit withstand up to 120 kA at 400V for fault survival
• Operates to +60 °C enabling high-temperature installations
• Indicator fitted to show fuse status at a glance
