The innovative SASY 60i busbar system provides maximum efficiency in the switching cabinet
Bonn, March 2008 – SASY 60i – safe and reliable: In combination with the new generation of Moeller’s motor protectors and circuit breakers, SASY 60i provides a universal UL-certified solution for switching, protecting and distributing power.
The modular SASY 60i busbar system by Moeller has been conceived for the efficient distribution of power in the switching cabinet. Thanks to busbar adapters, space-saving feed and output switches can be mounted quickly onto the busbar system.
Optimized busbar profile
The system offers many advantages. For example, the SASY 60i uses double-T-profile bars, thus reducing the time and effort needed to prepare the contact points. The profile uses very few busbar supports for very high rated peak withstand currents (Ipk); it thus optimally utilises the limited cabinet volume. In addition, power loss is discharged in the best possible manner thanks to the large surface area of the busbar profile. Thanks to the market-conforming 60 mm centre distance of the busbar, the system is compatible to other set-up components such as slide fuses or NH fuse switch disconnectors or the new D0-load disconnector switch using the D02-LTS/63/3-R type of fuse. The latter provides for all-pole switching of the load (quick break) independent from manual switching, and safe fuse replacement in a voltage-free status. The device comes as standard with a flashing signal and contact position indicator, which either inform the user about a faulty fuse or show the switching status 0 or I of the device. The plug-type technology without fuse carriers (fuse plug) not only reduces the power loss of the protective device while it is in operation, but also enables the user to replace a hot fuse after tripping without having to touch it with his hands. D02-LTS/63/3-R is available as a 3-pole and 4-pole version and it is extremely space-saving thanks to its overall width of 27 mm only. Retention springs making it easy to insert type D01 and cylindrical size 10x38 fuses in the fuse plugs are included in the scope of delivery. The load disconnector switch can of course be locked out and sealed.
Short installation time thanks to pre-assembly
Moeller offers direct and reversing starters up to 15 kW, fully mounted on busbar adapters. These fully assembled units consist of one PKZM0 motor protector and one or two DILM contactor(s). In order to mount these, they only need to be clicked in place on the busbar; this guarantees reduced assembly times and costs.
Special features of the device adapters
The device adapters offer a special functionality in that they can be mounted onto different profiles and busbar thicknesses. The adapters connect to the motor protector and circuit breaker directly over the busbars, comfortably and without requiring any boreholes, up to 630 A.
By reducing the width of the adapter to 45 mm, it has been possible to match it to the width of the motor protectors and contactors. The actual mounting surface on the busbar system is thus optimised, helping to save room in the switching cabinet.
Safety is always first priority
Safety for people and for the system is the most important factor with all our developments. Here, this prerequisite has been met with a comfortable connection on the rear side. It allows for a safe connection from the circuit breakers to the busbar adapters. In addition, mounting times are significantly reduced. Modular system covers guarantee optimised shock protection all around, and thus the highest possible level of safety.
A system designed for worldwide use
Together with its system components, the SASY 60i busbar system is designed for worldwide use in control cabinets for mechanical and system engineering. Its design has even taken into account the greater clearance and creepage distances that must be observed in the U.S. pursuant to UL 508A.
For busbar applications that have not been type-tested, UL508A allows an ampacity of 1000A/inch2 (1.55A/mm2). This value may be higher if the product or the application has been tested accordingly. Moeller has conducted extensive tests for the user’s maximum benefit in using SASY 60i busbar systems. The advantage of such tests is that one can use busbar systems designed for higher rated currents than the default value allows. A busbar of size 30x10 mm for example can be charged with 630A instead of 465A only.
Since SASY 60i requires fewer system components, the need to stock parts and to place orders is diminished with the new Moeller busbar system.
