Allen-Bradley 194R-NJ030P3 3-Pole Disconnect Switch

Allen-Bradley 194R-NJ030P3 is a three-pole disconnect switch intended for safe isolation of three-phase power in industrial control panels and motor-control centers. It is rated for 30 A and supports voltages up to 600 V AC or 250 V DC, allowing it to interrupt both AC motor circuits and DC control circuits as part of a larger protection scheme. The NJ030P3 designation identifies the specific 3-pole, 30-amp variant within the 194R family and signals a compact, panel-mountable form factor designed to be installed in electrical cabinets or MCC enclosures. This device provides a clear, mechanical means to open or close a circuit, enabling maintenance, servicing, or safety procedures with the circuit isolated from power sources. In typical installations, it is used upstream of loads that require a dependable disconnect as part of a broader protective strategy, often alongside fusing or other overload protection and within a properly sized enclosure to protect against dust, moisture, and incidental contact. The 194R line is chosen for its robust construction and straightforward disconnection capability in demanding industrial environments.
