The busbar system with pin-type terminals can be used for all 5SJ6 ...-.KS and 5SY miniature circuit breakers with or without mounted auxiliary switch (AS) or fault signal contact (FC).
Busbars are available in 10 mm2 and 16 mm2 versions.
The 5ST3 7 busbar system with busbars that can be cut to any length required.
The extremely flexible 5ST3 6 busbar system with fixed lengths enables installation in any length as the busbars can be overlapped. No further need for time-consuming tasks, such as cutting, cutting to length, deburring, cleaning of cut surfaces and mounting of end caps.
Any free pins on the busbars can be made safe by covering with touch protection.
For further information on bus-mounting miniature circuit breakers with residual current operated circuit breakers, please refer to the chapter "Residual current protective devices".
Benefits
Between the devices, the busbar, located at the bottom and behind the conductor, provides an optimum wiring space with easy view of the inserted conductor. This enables easy control of connections.
The ability to overlap the busbar mounting enables a crosssection enlargement of up to 32 mm2 using the respectivecomponents, 10 and 16 mm2.
By overlapping the busbars with fixed lengths, it is possible to achieve device combinations with any number of devices.
The fact that the connection of the conductor is always clearly visible facilitates control and insertion of conductors of all pole types and considerably reduces mounting times.
