Statistics tiastar ™ Arc Resistant MCCs ____________________________ Arc flashes are responsible for about 80 percent of electrical accidents in the U.S. each year1. In human terms, they are responsible for hundreds of deaths, thousands of serious injuries, and significant lost work time every year.2 ____________________________ Bureau of Labor Statistics Census of Fatal Occupational Injuries

Arc Flash tiastar ™ MCCs Arc flashes are responsible for about 80 percent of electrical accidents in the U.S. each year. Personal Protective Equipment (PPE) can help avoid or reduce the severity of injuries Electrical equipment manufacturers have applied strengthened structural design to improve the safety potential of its Switchgears. Standards for performance-testing arc-resistant features defined for switchgear not MCCs. Manufacturers are using those standards for testing arc-resistant MCCs.

Prevention tiastar ™ Arc Resistant MCCs The simplest and most effective measure to prevent an arc flash is to shut off all power to the equipment to be worked on. Siemens advises that individuals should only work on MCCs or other electrical equipment after all power to the equipment has been turned off. Arc flash prevention, safety training and PPE can only go so far in keeping workers out of harm’s way should an arc fault occur. Although PPE can provide protection from an arc flash, it still cannot protect an operator from being struck by enclosure doors blown off or open from an arc flash – or from fragments ejected from a disintegrating enclosure.

Arc Mitigation & Arc Resistant Equipment tiastar ™ Arc Resistant MCCs Arc Mitigation & Arc Resistant Equipment Arc flash hazard mitigation and arc-resistant features. Designed to complement each other. Arc flash mitigation features: To keep the workers beyond the Arc Flash Boundary To shorten the arc flash duration Arc resistant equipment: To make sure that, in the event of an arc flash when the MCC’s doors are closed and latched, the equipment will contain the explosion, directing the arc blast, including its heat, plasma and pressure, away from workers.

Arc Flash Mitigation tiastar ™ MCCs Arc Flash Hazard Mitigation Features available in tiastar MCC: Dynamic Arc Flash Sentry (DAS): This is a patented feature available in both Siemens MCCs and type WL Low Voltage Switchgear. DAS (alternate parameter settings) can be activated using a variety of activation methods (keyed switch, occupancy sensors, light curtains, etc.). Visual verification of DAS activation can be as simple as a pilot light or more elaborate such as horn and strobe light.

tiastar ™ Arc Resistant MCCs Siemens is the first manufacturer in the industry to have Underwriters Laboratories (UL) observe and validate the testing of its arc-resistant tiastarTM MCC model. The tiastar arc-resistant MCC successfully met the testing criteria required by the standards, and a qualified, independent third-party has confirmed this satisfactory performance.

tiastar ™ Arc Resistant: Protecting your most valuable asset – your personnel Reinforced enclosure and doors, with bolted rear covers: Increased hinge and latching locations combined with additional structural supports ensure sections will withstand, contain and re-direct internal arcing fault incident energy. Insulated vertical bus bar system: Isolates energized components preventing inadvertent contact and propagation of arcing faults. Automatic shutters in plug-in unit compartments: Isolates the plug-in location to prevent inadvertent access and lowers the risk to personnel. Internal venting system: The structure components are designed to vent and channel arc flash gasses to the back and out the top of the MCC. 13 13

Features tiastar ™ Arc Resistant MCCs Arc flashes present a serious safety risk. The best protection is prevention by enforcing strict safety rules, mandate proper maintenance, and support that with regular safety training. Advances in technology have enabled electrical equipment the means to design and engineer much more arc flash safety features into their products and systems such as switchgear and MCCs. While standards continue to evolve, they inherently follow these kinds of innovations. It is important that the application testing of new safety features be validated by a qualified third-party like UL to ensure that the safety features work as intended and to prevent tragic accidents.
