Motor Starters & Breakers
IPD is a one stop solution when it comes to motors, its control and protection. IPD offers ABB’s diverse range of motors from three phase synchronous motors to servo motors. ABB’s application specific Variable Speed Drives (VSDs) are dynamic and energy efficient. Furthermore, a range of diverse application specific ABB motor starters and breakers inclusive of Manual Motor Starters, Enclosed DOL Starters – DRAF, Universal Motor Controllers, Soft Starters, Contactors and overloads can be found. Motor breakers, as the name implies are used to protect the motor circuit against overload, short circuit, and phase failures by disconnecting the motor and blocking the flow of current.
Manual motor starters are thermal and electromagnetic motor breaker devices which are widely used in the industry to secure motor circuits. Apart from manually switching the motors ON and OFF, the motor starters manufactured by ABB, offer fuse less protection hence saving expenses as well as space. These three pole devices furthermore exhibit their benefits including the compact design, harmonized main accessory range, systematic installation procedure, and simple connecting links to construct direct-on-line (DOL) starters. Additionally, less machine downtime & reduced maintenance cost can be assured due to the equipment protection provided by the manual motor starters. The main features of ABB’s manual motor starters include manual control, rotary handle operation, adjustable current setting, disconnection function, temperature compensation, test function for testing of the trigger process, DIN rail mounting and up to 100 kA of short-circuit service breaking capacity.
Manual motor starters consolidate the functions of several modules such as circuit breakers, overload relays and disconnect switches. Therefore, they are offered with some accessories including auxiliary contacts, signaling contacts, undervoltage releases, shunt trips as well as power in-feed blocks. The features define three main ranges of manual motor starters namely, MS116, MS132 and MS165. Divided accordingly to simplify preference, coordination as well as installation, the above-stated motor starters provide comprehensive benefits fitted for every application.
The Universal Motor Control UMC100.3 is future-ready and equipped to take your motor control to the next level. With outstanding ease of use, unrivalled communication, and simple configuration, the smooth running of your operations has never been so simple. ABB’s intelligent motor controllers combine motor protection and control functions, fieldbus and Ethernet communication, and fault diagnosis in a single device. They provide detailed operational, diagnostic, and service data continuously, giving any plant an effective data source for predictive maintenance systems. DRAF is an enclosed direct-on-line starter embedding AF technology. It is used for motor starting up to 7, 5 kW and 10 hp and complies with both IEC and UL/CSA standards. TF42 thermal overload relays for motor protection should be selected and ordered separately according to motor's nominal current.
A soft starter is a device that starts motors with reduced power supplied at the beginning-up. Lowering the power decreases potentially damaging electrical and mechanical shocks on the system. Soft starters are a blend of a controller and overload protection. Soft Starters place a device called a reduced voltage starter, or soft starter, between the motor and the incoming utility line to control the amount of current fed to the motor.
Soft starters facilitate the AC induction motor to speed up in smaller steps, resulting in less current drawn than with a traditional motor starter. Due to decreased voltage, torque is also reduced resulting in a soft, or easy start. Soft starters are used on all types of AC and DC motors. They are most commonly used with the AC squirrel cage induction motor because of its simplicity, robustness and dependability. Because it offers soft starting and stopping, a soft starter is the ideal compromise between a direct-on-line or star-delta starter and a variable speed drive in many full-speed motor applications.
