■
Overview
These miniature circuit breakers are used for the protection of
plants with switched neutral conductors in distribution boards
with little space. They are just a single modular width.
Compact busbars facilitate installation in space saving distribution
boards.
The devices are approved for worldwide use according to IEC
standards for systems up to 250 V AC. 60 V DC per pole is
permitted in DC systems according to IEC standards.
■
Benefits
•
Auxiliary switches and fault signal contacts from the high-capacity
range can be freely mounted on these miniature circuit breakers.
This increases availability and cuts down on logistics.
•
By actuating the latching slide, the miniature circuit breakers
can be quickly and easily removed from the assembly.
•
For 3-pole busbars, the 5ST3 6 busbar system is used – a
universal system, suitable for all miniature circuit breakers.
•
The infeed can be implemented either from the top or the
bottom. Additional terminals with lateral insertion of conductors
facilitate mounting when using large conductor cross-sections.
