SENTRON switching devices offer reliable disconnection and protection for people, machines, and electrical installations to maintain high system integrity at all times.
Empower your design process with simplified engineering, fast installation, and flexible retrofit options supported by high-quality CAx data.

They meet all the requirements for main control, EMERGENCY-STOP, and maintenance switches. Simple to install and easily retrofitted. LV HRC fuse links are available for up to 800 A available.

Suitable for main control, EMERGENCY-STOP, and maintenance switches. Offers versatile connection options and operating mechanism designs. Terminal covers ensure enhanced touch protection. Contact postions are visible at all times.

The portfolio includes automatic transfer switching equipment (3KC ATSE), a remote-controlled variant 3KC RTSE and a manually operated version 3KC MTSE for up to 1,600 A, all IEC 60947-6-1 and IEC 60947-3 compliant.

IEC 60947-3, DIN VDE 0660 Part 107, and EN 60947-3 certified manually operated switch disconnectors or On/Off, EMERGENCY-STOP, and main control switches according to DIN EN 60204-1. UL508 and UL489 compliant designs available.

The switches are available in five performance sizes up to 630 A and are very space-saving, thanks to their compact design. It’s easy to install these devices on mounting plates or rails or in busbar systems.

The 3NJ4 and 3NJ5 in-line fuse switch disconnectors combine load switching and disconnect functions in a single system. Thanks to their integrated LV HRC fuse, they also protect systems in the case of overload or short-circuits.

Feature an integrated switching device with single or double interruption capacity. Especially suited for applications where large numbers of cable runs for power distribution are housed in extremely confined spaces.

Switching devices can serve to switch lighting systems, motors, and other devices on and off. Switching devices for manual operations enable users to switch electrical loads on and off manually. No tools needed for installation.

Our remote control switches for chopper actuation, switching relays, or Insta contactors perform switching operations for electrical loads automatically. They enhance safety and convenience and reduce energy consumption.

We offer you a broad range of design variants to VDE, UL, CEI, or CEE standards. The short-circuit-proof transformers and power supply units for many voltages and power levels meet all requirements of extra-low-voltage systems.

The 3KC ATC6300 and ATC 6500 transfer control devices enables safe and fault-free switching between two power sources. The 3KC is deployed above all where a mains failure can have critical consequences.
