Abb 40A 4P Isolator- R0040 Shd 204/40

SHD204/40 is a four-pole isolator switch, also known as a disconnect switch or isolating switch. It is designed to physically disconnect electrical circuits from their power source for maintenance, repair, or safety purposes., "40A" designation indicates the maximum rated current of the isolator switch, which in this case is 40 amperes. This means the isolator switch can safely handle electrical currents up to 40A., "4P" designation signifies that the isolator switch has four poles. In electrical terminology, a pole refers to a set of contacts that opens or closes the circuit., SHD204/40 may feature an enclosed design, providing protection for the internal components against environmental factors such as dust, moisture, and accidental contact., isolator switch is equipped with a handle that allows users to manually operate the switch, turning it on or off as needed.
