Schneider Electric 50A Rail Mount Fuse Holder for 14 mm x 51 mm, 3P-Pole, 690V ac DF143C

Schneider Electric DF143C Rail Mount Fuse Holder offers a high-quality, industrial-grade protection solution for electrical circuits requiring 50A current rating and 690V AC voltage. Its compact, three-pole design fits standard 35 mm DIN rails, ensuring a straightforward installation within electrical control panels and automation systems.

The fuse holder accommodates 14 mm x 51 mm fuse cartridges, providing robust protection and clear indication of fuse status through an integrated indicator. The device is engineered to withstand high short-circuit stresses up to 120kA at 400V, making it reliable for industrial power distribution and motor control applications.

Constructed to operate efficiently in environments ranging from -20°C to 60°C, this fuse holder is suitable for high-temperature operations, ensuring durability and consistent performance. Screw clamp terminals allow secure and reliable cable connections, supporting conductors from 2.5mm² to 25mm² for single wires and 2x10mm² for dual wires.

This product complies with standards CSA, UL512, IEC 60947-3 and is RoHS certified, meeting international quality and safety norms. Its impulse-withstand rating of 8kV provides protection against transient voltage spikes common in industrial power supplies.

Applications include motor starter panels using tubular fuse links, distribution blocks in manufacturing switchgear, and control systems requiring remote trip signalling. Its design allows easy clipping onto DIN rails with vertical mounting tolerance of ±23°, providing flexibility in panel installations.

This fuse holder features screw clamp terminals for secure conductor connections. It mounts on standard 35 mm DIN rails for ease of installation. The fuse condition indicator provides clear visual status of fuse health. Designed for operation in temperatures ranging from -20°C to 60°C.

Withstands short-circuit stresses up to 120kA at 400V for enhanced safety. Suitable for use in motor starter panels and manufacturing switchgear distribution blocks. Compatible with tubular fuse links and fuse cartridge strikers for remote trip signaling.

Impulse withstand capability of 8kV ensures resilience to transient industrial overvoltages. Ideal for both AC and DC control systems and retrofitting on DIN rails.
