Fuse base 14x51mm 50A 3P DF143C

Safe and reliable protection of electrical circuits.

This three-pole fuse base, designed for 14x51mm fuses with a current of 50A, is a key element of electrical installations requiring high reliability and safety. Designed by Schneider Electric, it is an ideal solution for both residential, industrial buildings, and OEM manufacturers. DIN rail mounting ensures easy installation and integration with existing systems.

Functionality and technical parameters

This base is a low-voltage fuse disconnect switch, designed to work with gG (overload and short-circuit) or aM (for motor applications, protecting against high peak currents) fuses. Its construction provides protection against overloads and short circuits in circuits with a rated voltage of up to 690V. A width of 4.5 modules allows for efficient use of space in the switchboard. Made of high-quality materials, it ensures durability and resistance to environmental conditions (IP20 protection).

Protection of circuits with high load is ensured by a rated current of 50A. The device works with installations up to 690V and accepts standard cylindrical fuses with dimensions of 14x51mm. Mounting is convenient on a DIN rail, and the three-pole construction guarantees comprehensive protection. A width of 4.5 modules allows for optimal use of space in the switchboard, and compliance with IEC EN 60947-3 confirms the safety and reliability of the device.

Installation and application

The fuse base is adapted for connecting rigid and flexible copper conductors with a cross-section from 2.5mm² to 25mm². The tightening torque of the connections is 3.5 N.m (with a PZ2 screwdriver). Thanks to the possibility of mounting on a DIN rail, installation is quick and easy, which will be appreciated by both professional installers and people performing electrical work themselves. The device operates at an ambient temperature from -20°C to +60°C, which ensures its reliability in various operating conditions.
