Low Voltage Fuse Bases

General features:

The dimensions of LV HRC fuse bases of sizes 00-3, 160A-630A for the counting wall are standardized according to DIN 43620-3.
Its technical values ​​are placed according to IEC / EN 60269.

They are designed for AC690V and DC440V voltages.
The bases are usually equipped with screw terminals for cable lugs.
The fuse bases are mounted on plates inside the low voltage distributors or installed in the insulation housings.

Medium Voltage HRC Fuse-Links

To prevent damage to the windings, transformers must be protected against thermal and dynamic defects caused by short circuits. JEAN MÜLLER medium voltage and high breaking fuses have been specially designed for this application. The standardized characteristics of these fuses are coordinated with other protection devices. Thus, there is no need for complex calculations of short-circuit currents.
JEAN MÜLLER fuses are designed according to the international standard IEC / EN 60282-1 and DIN VDE 0670-402.

Low Voltage Fuse-Links

While the maintenance-free fuse always limits the impact on systems and components if a short-circuit occurs, special applications require specific solutions. Here, fuses for safe work and semiconductor protection must break fault currents especially quickly, fuses to protect transformers are adapted to individual requirements and photovoltaic systems bring completely different challenges, as well as handling high DC voltages, our fuses have been optimised for the narrow band between the permitted operating current and typically low short-circuit currents.
In conjunction with our NH fuse-bases, the D and D0 fuse range and our HH fuse-links from the IKUS series, our products always bring you peace of mind.

Load Break Switch (SASIL)

The switch is equipped with an independent manual action mechanism.

A screw terminal for the connection is available on the output side.

Used for the three-phase system up to 690V and plates for the sub-distribution of low voltage assemblies according to IEC / EN 60439-1, for industries, power plants and service applications in a building. Its horizontal fit and compact dimensions allow a large number of sockets in a limited space. A uniform width, depth and grid dimension of 25mm strip height (75mm, 150mm) allows for quick engineering and assembly of components of different sizes used inside the cabinet. The line and control auxiliary of the circuit systems are automatically connected via the terminal strip connector system.
