1336-B025-ECF

The 1336-B025-ECF is an out Frequency AC Drive designed by Allen-Bradley. It comes with a large frame that measures 11.13 by 8.76 by 18.75 inches. The Alternating Current (AC) drive, which belongs to the 1336 series, has a maximum torque of at least 2.26 Newton-meter (about 20 pounds per inch). The 1336-B025-ECF has a “B” drive rating, which means that the drive can run on three different input voltages: 460 Volts AC, 415 Volts AC, and 380 Volts AC. Its output is rated at 41.0 Amps. At 380 Volts AC, this Allen-Bradley AC Drive produces 27.0-kilo Volt-Amps (kVA), while at 415 Volts AC it produces 29.0 kilo Volt-Amps (kVA), and at 460 Volts AC, it process 33.0-kilo Volt-Amps (kVA). The drive’s “B” rating also indicates that the module has a frequency that ranges from 50 to 60 Hertz and incorporates 3 phases. In order to maintain an efficient flow of such a high voltage rating, the 1336-B025-ECF should possess a copper wiring temperature of 75 Degrees Celsius and the wire should be 16 millimeters in size. The drive also features a NEMA Type 4 enclosure with a protection index rating of 56.  The 1336-B025-ECF enclosure comes with a 25 or 30 Amp rating code which shows that it can withstand high-voltage discharge during the drive’s operation.

Some of the components (like printed logic circuits) that are attached to the 1336-B025-ECF are quite susceptible to high voltage, so it is important to turn off the drive before carrying out any maintenance servicing or part replacement so as to avoid severe damages to the system components. Note that at the terminals electronic discharge might go as high as 1.6 kV Direct Current, so make sure to use a well-calibrated equipment to measure the voltage across these terminals before disassembling the 1336-B025-ECF drive.
