ABB motor circuit breaker model parameters and application accessories

Overview of ABB Motor Circuit Breakers

ABB motor circuit breaker is a kind of protection device that can provide better and more complete protection for electrical systems and motors, and it also integrates motor control and protection functions. Usually, this equipment is mainly suitable for manual start and stop of motors, and can provide protection for different faults such as short circuit, overload, and lack. The non-fuse motor circuit breaker protection scheme can not only save cost and space, but also ensure a quick response when a short-circuit fault occurs, and it only takes a few milliseconds to complete the shutdown action of the motor.

The ABB motor circuit breaker MS116 model has a rated current range of 0.1A to 32A, which can provide high-efficiency and reliable protection against short circuits, overloads and phase failures of motors and circuits. The setting value of the motor circuit breaker should be consistent with the rated current of the motor, and the motor generally needs a higher current to complete when starting. At the same time, during the starting process, the circuit breaker will let the starting current pass without causing tripping. The figure below shows the international standard curve when the motor is started and running.

ABB motor circuit breaker solutions

1. Applied to motor starting solution

With complete specifications of circuit breakers and abundant accessories, it can meet different types of motor starting work, including direct starting, star-delta starting and reversible starting. The protective devices recommended here are as follows:

◆Motor circuit breaker (MMS);

◆Overload relay (TOL and EOL);

◆Intelligent Motor Controller (UMC);

◆Molded Case Circuit Breaker (MCCB);

◆Air circuit breaker (ACB);

◆Fuse.

2. Applied to electrical system solutions

In industrial applications with high short-circuit current, each motor branch generally requires special backup protection fuses or short-circuit current limiters. In this way, more space is required, and the upper-level circuit breaker must be able to achieve selective protection. The self-resetting S900-SCL-SR limiter has a high short-circuit backup protection capability, which can reach 100kA at 440V, 50kA at 690V, or 80kA at 690V. The short-circuit current limit with two series connection Device.
