Allen-Bradley, a part of Rockwell Automation, manufactures the 194R-NJ030P3 switch. The fused disconnect switch is rated for 600 volts AC and 250 volts DC. The 194R-NJ030P3 switch has a current rating of 30 amps and a DIN rail mounting style. The 194R-NJ030P3 switch has four poles and comes available in three-phase or single-phase configurations. The 194R-NJ030P3 switch should be operated in an optimally ventilated atmosphere. The machine operates in temperatures ranging from -2 to 55 degrees Celsius. The temperature range for ambient storage is -40 to 65 degrees Celsius. The ambient range of temperature for an enclosed switch is -20 to 40 degrees Celsius. According to the IEC 60947-1 standard, the unit should be maintained at a height limit of 2000 meters above sea level. Allen-Bradley fused disconnect switches, such as the 194R-NJ030P3, increase their current ratings to 1250 Amps for IEC compliance and 800 Amps for UL compliance. The 194R-NJ030P3 switch is appropriate as a motor terminating alternative as well as a way of isolating the service entry (UL). The 194R-NJ030P3 switch is available with a flange mounting option or a rotary grip. Additionally, the 194R-NJ030P3 switch supports cable actuation in addition to rod or shaft actuation. The 194R-NJ030P3 switch is rated at 200 kA and is NFPA 79 compliant. Fusible disconnect switches from Allen-Bradley have a high short circuit current rating and a touch-safe design. The 194R-NJ030P3 switch has electrically separated phases to ensure that phase-to-phase shorting is minimized. The device complies with RoHS regulations and has double break switching for the whole fuse line, as well as load side isolation whenever the switch is turned off.
