SENTRON fuse systems

Why SENTRON fuse systems?

Prevent damage and downtime, and protect against serious accidents, fires, and financial losses with Fuse systems, which disconnect the circuit safely as soon as an overload or short-circuit occurs.

Siemens' complete range of SENTRON fuse systems offers an economical and reliable solution for versatile short-circuit protection.

Fuses and fuse systems include:

SENTRON 3NA COM LV HRC
SENTRON NEOZED
SENTRON DIAZED
SENTRON Cylindrical
SENTRON 3NA, 3ND LV HRC
SENTRON SITOR Semiconductor
SENTRON Photovoltaic

Key Benefits

Protect cables and lines 

Fuses protect electrical systems and devices and can also be used for backup protection of components like residual current circuit-breakers, miniature circuit-breakers and molded case circuit breakers.

Protect motor circuit switchgear

Economical and reliable, fuses have considerably lower cut-off currents and values as compared with other protection devices.

Protect semiconductors

Partial and full-range fuses combine semiconductor and cable protection — guarding against overload for diodes, thyristors, GTOs, IGBTs and more.

Featured capabilities

Renewable energy system support

Fuse systems protect photovoltaic and wind power systems from "reverse current" risks caused by faulty solar components.

Versatility and safety

In a variety of applications, fuse systems are a safe choice for disconnecting the circuit as soon as an overload or short-circuit occurs. This prevents damage to electrical equipment, installations and buildings.

Protection against overload

Our wide range of SENTRON fuse systems protect against the result of overload, helping to avoid accidents, fires and financial losses.

FUSE SYSTEM

SENTRON 3NA COM

The SENTRON 3NA COM offers overload and short-circuit protection, a smart, digital solution and, in combination with SICAM EGS, current direction detection for greater transparency and safety in distribution substations.

FUSE SYSTEM

SENTRON NEOZED

The easy-to-use NEOZED fuse system is used in distribution technology and industrial switchgear assemblies. The system is also approved for domestic installation.

FUSE SYSTEM

SENTRON DIAZED

The DIAZED fuse system was first developed by Siemens in 1906. Still considered the standard fuse system in many countries, it is widely used in the harshest industrial applications and environments.
