ABB Australia announces the launch of its new SafeStart low voltage motor control centre (MCC) technology. SafeStart motor control centers improve safety, equipment reliability and ease of maintenance for operators of demountable type MCCs in the mining and minerals industry.
ABB conducted a series of market surveys in Australia and based the design of the SafeStart MCC on direct feedback, helping to address the key needs of operators and owners of local mine sites.
Underlining the importance of safety in the mining market, Kelvin Wong, Low Voltage Systems manager for ABB in Australia explains that the new module interlock system developed for SafeStart MCCs highlights the company’s ongoing commitment to safety in the mining industry. Several other design elements incorporated to address the needs expressed by ABB clients in relation to additional safety were successfully verified by conducting a series of additional arc fault tests, greatly exceeding the requirements of any Australian or IEC standards.
The SafeStart MCC modules are designed to improve safety for operators and electrical maintenance workers with enhanced protection against arc faults and interlocking mechanisms. This allows the main switch handle to be padlocked in the OFF position with the door open or closed, and also prevents insertion or withdrawal of the demountable module when the main switch is in the ON position.
ABB’s demountable SafeStart low voltage motor control centres have been designed to operate in harsh conditions such as ambient temperatures between -5°C and 50°C, and dusty environments, which demand protection ratings of up to IP54. Temperature rise tests and internal arcing fault tests have been conducted under the worst conditions of IP54 without extrapolation or assumptions.
The modular design of the SafeStart MCCs simplifies maintenance. All demountable modules come in standard sizes and are provided with facilities to allow for quick interchange or replacement of modules within the framework. Main busbars feature a maintenance-free construction and distribution bars are fully phase-segregated, dramatically reducing the probability of an arc flash.
