1494C-DH622-A4-B1-F

The Allen-Bradley 1494C-DH622-A4-B1-F Switch is a 1494C cable-operated disconnect switch. It has a switch size and current rating of 200 Amps and an IEC-rated insulation voltage of 250 Volts or 600 Volts. It has Class H fuse clips with a painted metal handle and 1 N.O. auxiliary contact. It is a fusible disconnect switch with a right-hand mechanism that has a kit that includes a trailer fuse block, a non-metallic handle, and switch and fuse clips (for the kit to be complete, the users must add the cable mechanism code). The Allen-Bradley 1494C-DH622-A4-B1-F Disconnect Switch has a 4-foot cable length. The operating handles have various degrees of protection and they can be Painted Type 1, 3R, 4, and 12 handles and non-metallic Type 1, 3R, 4, 4X, and 12 handles. The cable-operated switch has a mechanical life of about 8000 operations and a switching frequency of about 300 operations per hour maximum. Also, it has an electrical lifespan of about 6000 operations at the rated current.

The Allen-Bradley 1494C-DH622-A4-B1-F Disconnect Switch has an ambient temperature range of -20 to 60 degrees Celsius (-4 to 140 degrees Fahrenheit) when it is open, -20 to 40 degrees Celsius (-4 to 104 degrees Fahrenheit) when it is enclosed, and  -40 to 65 degrees Celsius (-40 to 149 degrees Fahrenheit) when it is in storage. The 1494C-DH622-A4-B1-F disconnect switch is classified with the Class H fuses and it has a short circuit withstand capability of 10,000 Amps of current. It complies with the NFPA 79 standards by being connected to the switch throughout. It has an operating altitude of 2000 meters and a maximum relative humidity of 90% at 20 degrees Celsius (68  degrees Fahrenheit) and of 50% at 40 degrees Celsius (104  degrees Fahrenheit) according to the IEC 947-1 standards.
