Switching, Protecting and Measuring with SENTRON

3WL Air Circuit Breakers

SENTRON 3WL air circuit breakers offer a very flexible applicability and integrated communication capability. They optimally meet the increased requirements placed upon air circuit breakers particularly with regard to the operation and monitoring of network processes in connection with electronic control systems. The quality of this range sets new standards worldwide.

3VL Molded-Case Circuit Breakers

Featuring a particularly compact design, the SENTRON 3VL molded-case circuit breakers meet all requirements placed upon space-saving electrical distribution systems – in a power range from 16 A to 1600 A.

3LD Main and EMERGENCY-STOP Switches

The application options of SENTRON 3LD disconnector units are manifold. In addition to isolation from the mains, they ensure the safe disconnection of the entire electrical equipment and can be employed for switching three-phase motors as well as air-conditioning systems up to 45 kW.

3KA/3KE Switch Disconnectors

The SENTRON 3KA/3KE switch disconnectors are the experts for fuseless disconnection operations in all low-voltage networks. Available as three- or four-pole version, they perfectly master “disconnection” tasks and “switching under load” in distribution boards employed in residential and functional buildings as well as in industrial power distribution boards.

3KL/3KM Switch Disconnectors with Fuses

3KL/3KM switch disconnectors are ideally suited as main and EMERGENCY-STOP switches. Thanks to their fused design, they additionally provide short-circuit and overload protection. In connection with SITOR semiconductor fuses, they even master high requirements.

3NJ62 In-Line Plug-In Switch Disconnectors with Fuses

In contrast to the 3NJ4 in-line fuse switch disconnectors, the devices of the 3NJ6 range are equipped with an integrated switching element with single- or double-break. They are particularly suitable for applications in which many cable outlets for power distribution have to be accommodated in minimum space.

3NJ4 In-Line Fuse Switch Disconnectors

Our 3NJ4 in-line fuse switch disconnectors combine the functions "load switching" and "disconnecting" in a single system. Thanks to an integrated LV HRC fuse, they additionally provide reliable overload and short-circuit protection. The very compact disconnectors can also be optimally mounted in confined spaces thanks to manifold connection options.

3NP Fuse Switch Disconnectors

Our 3NP range offers reliable protection against overloads and short circuits. The devices are perfectly suited for high requirements, for example thanks to their large and clear inspection window, through which the inserted fuses can be clearly recognized as well as due to the soundly visible isolating distance, which is highly advantageous for maintenance.

8US Busbar Systems

Mounting current-limiting (protection) devices such as fuse switch disconnectors and circuit breakers as well as complete load feeders directly onto busbars has become a commonly used technique. Our 8US busbar system – in 40 mm or 60 mm depending on your requirements – provides an efficient solution.

SENTRON PAC3200

is a multi-function meter for recording and displaying electrical parameters and energy. It is used to record and display all relevant network parameters of an electrical plant, and monitors these permanently.
