5SY6 Miniature Circuit
Breakers
SENTRON Protection, Switching, Measuring and
Monitoring Devices
Miniature circuit breakers are used to protect plants in buildings and infrastructures
for industrial applications. The devices can be used as main control switches for dis-
connecting or isolating plants.
Additional components offer
increased flexibility
Additional components, such as auxiliary
switches, fault signal contacts, shunt
releases, undervoltage releases, remote
controlled mechanisms and RC units
enhance the miniature circuit breaker's
overall functionality.
Quick and safe assembly
Integrated movable terminal covers located
at the cable entries ensure the terminals
are fully insulated when the screws are
tightened. Manual quick-assembly systems
guarantee convenient time-saving assem-
bly without requiring any tools.
Highlights
Touch protection when grasping the
device – exceeds VBG4/BGV A3
requirements
Busbar assembly devices are replaced
faster and with less effort
The infeed can be operated from the
top or bottom

5SY6 miniature circuit breakers
Overview
The devices are approved for worldwide use according to IEC
standards for systems up to 250/440 V AC. 60 V DC per pole is
permitted in DC systems.
For North America, we also have additional certification to
UL 1077 for use as "supplementary protectors" in systems up to
480Y/277 V AC. For use in ship building, the devices also have
numerous certifications according to shipping classifications;
BV, DNV, GL and LRS.
Benefits
• Optional top or bottom infeed as the terminals are identical
• Clear and visible conductor connection in front of the busbar
facilitates controls
• Large and easily accessible wiring space enables easy inser-
tion of conductor in the terminal.
• Integrated movable terminal covers located at the cable
entries ensure the terminals are fully insulated when the
screws are tightened
• The effective touch protection when grasping the device
considerably exceeds the requirements of VBG 4/BGV A3.

• Manual snap-on fixing and release systems that require no
tools enable fast assembly and disassembly of MCBs
• Marked labeling field on all modular installation devices for
uniform, quick and easy identification.
• Quick and easy manual removal of MCBs from the busbar as-
sembly if connections need to be changed.
• Time-saving replacement of parts as busbars no longer need
to be freed from adjacent devices.
• Double terminal chambers enable accommodation of 2 wires
of different cross-sections (up to 16 mm
2
in the bottom
chamber and 35 mm
2
in the top chamber).
Configuration
Switching capacity
Particular demands are made on miniature circuit breakers with
regard to switching capacity.
The values are standardized and are determined according to
the test conditions of IEC/EN 60898-1 or DIN VDE 0641-11.
For other test conditions, it is also possible to specify values that
are higher than those of IEC/EN 60898 or DIN VDE 0641-11.
One such standard is IEC/EN 60947-2 or DIN VDE 0660-101 for
circuit breakers.
