Industrial Shock Block Case Studies

The Industrial Shock-Block™ is a personnel protection device that effectively aids in safeguarding your people where equipment and water are present. The reliable performance and environmental considerations (humidity, ultraviolet, corrosion, and dust) of the SB6100 make it the perfect option for companies seeking high-quality protection for their employees. Below are a few examples of customers that discovered the many benefits of the Littelfuse Industrial Shock-Block™ SB6100.

Municipal Water Utility Company
Protects Workers from Shock Hazards

A municipal water utility company, that supplies water to more than three million residents, wanted to protect its workers from shock hazards. The facility had two tanks the size of Olympic swimming pools containing 7-10 hp submersible pumps running on 600 V. Once or twice a year the tanks must be cleaned by hand, and workers enter while the water is still present and the pumps are running. The solution was the Littelfuse Industrial Shock-Block™ SB6100 EGFPD. 電力会社は、各ポンプに電力を供給するモーター制御センターに EGFPD を設置しました。 The EGFPDs operate like an industrial ground-fault circuit interrupter. If a device senses a ground fault above a trip setting, it will open the circuit very quickly to protect workers from shock.

Large Solution Mining Company Protects
Employees from Electric Shock Near Pumping Station

溶液採掘には、一定の水の供給が必要です。 A large solution mining company has pump stations located near the water supply to pump the water in for processing. The water needs to be filtered before it is pumped to the mine so there is a filter screening the water intake. 2つ目のフィルターがポンプ場内に取り付けられていますが、それでも石、砂、破片がポンプ場に入り込みます。通常、年に一度、従業員は水中ポンプの助けを借りてサンプから破片を取り除く必要があります。 Having a submersible pump running while the employee is cleaning leaves them at risk for electrical shock. The Industrial Shock-Block™ was the solution. They mounted the EGFPD on the wall inside the pumping station along the river bank. Because the Industrial Shock-Block™ is lightweight, the wall-mount installation among the electrical cabinets worked for this application. Now when a worker goes into the pumping station to clean the sump, they will be protected by the Industrial Shock-Block™.

Brick Manufacturer Protects Workers
from Electrocution While Using Wet Saws

米国西部のレンガ製造工場では、住宅や商業用のレンガ、その他の建築材料として、粘土を加工しています。 Part of this process involves wet saws that operate at high voltage (480 V) and it is a wet process. The company managers wanted to make sure operators were safe from electrical ground faults. 工場の電気技師は、ユタ州ソルトレイクシティにあるリテルヒューズの販売代理店に懸念事項について相談しました。販売代理店の担当者は、リテルヒューズの機器漏電保護デバイス (EGFPD) の使用を提案しました。 The Industrial Shock-Block™ SB6100 was installed between the motor control center and the face-cut saws on a manufacturing line built in the 80s. そして実験してみたところ、30mAが厄介なトリップを防ぐ最低設定であることが分かりました。 If the device senses a ground fault at or above that threshold, it opens the circuit within 20 ms - fast enough to prevent worker injury or death from dangerous electrical shock.
