The Allen-Bradley 40021-566-01 switch is a disconnect switch. The disconnect switch helps to fully de-energize an electrical circuit for a certain period of time. It is used in the industrial sector for device maintenance. The switch disconnect is also made to be a safety device because it offers different protection features including short-circuit protection, overload protection, excessive temperature protection, and over current protection. The 40021-566-01 disconnect switch comes with an open enclosure and it should be protected from water sprays and pollutants. The disconnect switch can handle voltage ratings of up to 600 Volts AC maximum and current rating of 60 Amps. The disconnect switch has a small form factor and it is designed to save space. It can be easily installed on a floor by using mounted holes on the bottom. The disconnect switch is fully compliant with environmental and industrial standards including the CE, CSA, and UL standards.

The Allen-Bradley 40021-566-01 disconnect switch is manufactured using high-quality materials. The line terminal is equipped on the top side of the unit. It is a 3-phase safety disconnect switch. The operating frequency of the unit is 50/60 Hertz. The disconnect switch has an interrupting capacity up to 200 kA that allows it to handle a single unit that can address many applications. The 40021-566-01 disconnect switch has fast opening and closing times, and it can work independently of the operators’ actions. The disconnect switch can close on a short circuit and on a high inductive load. The operating temperature  of the disconnect switch should be set between 0 and 70 degrees Celsius in a clean and relatively humid environment.
