ABB’s IEC/EN 60947 series of electrical products are its core product line,covering key equipment such as circuit breakers,contactors,motor protectors,etc.,which are widely used in industries such as industry,energy,and construction.The following is a brief introduction to representative products based on the IEC/EN 60947 standard:
1.SACE Infinitus solid-state circuit breaker
Standard basis:Comply with IEC 60947-2 standard
Technical parameters:
The power supply circuit is switched on and off through semiconductor power electronic devices.The disconnection response speed is 100 times faster than that of traditional circuit breakers,and the service life is extended by 100 times.
No energy is released during the disconnection process,which almost eliminates the risk of arcing and improves the safety of personnel and equipment.
Application scenarios:
DC power distribution systems(such as energy storage,photovoltaics,UPS batteries,rail transit),especially suitable for occasions with extremely high requirements for disconnection speed and safety.
Advantages:
Small size,suitable for space-constrained environments(such as offshore systems,data centers).
2.Emax 2 air circuit breaker
Standard basis:Based on IEC 60947 standard
Technical parameters:
Rated short-circuit breaking capacity up to 200kA,rated current covers 630A to 6300A,and supports modular expansion.
Integrated intelligent functions(such as protection,logic editing,communication),and can be upgraded through ABB Ability Marketplace.
Application scenarios:
Industrial power distribution,new energy grid connection,data center power system,especially suitable for high current demand scenarios in complex environments.
Advantages:
Compact design(400mm wide unit can achieve 66kA breaking capacity),reducing installation space requirements.
3.AC contactor(A series)
Standard basis:Compliant with IEC 60947-4-1 standard
