ABB P14494-49 Enclosed Standard Braking Resistor, 15 Ohm, 2160 W, For Use With ACS150, ACS350 and ACS550 Series AC Drives
AC variable frequency drives are commonly used with a general purpose AC induction motor to form a reliable variable speed drive system. For applications that require faster deceleration rates or where motor speeds are exceeding the synchronous speed set by the output frequency of the drive (an overhauling load condition), a braking resistor is required. Braking resistors increase the braking torque capability of a variable frequency drive, producing faster and more controlled braking. The resistor dissipates regenerated power to keep the bus voltage from exceeding the rated limit of the drive. The type GCE enclosures are heavy gauge screened enclosures featuring a solid bottom and a built-in wiring compartment separated from the resistor assembly. The resistors are factory wired to a terminal block mounted in this compartment using high temperature PTFE or silicone wire. The terminal compartment also houses a normally closed thermal switch used for detecting resistor temperature overloads. During installation, standard 90 deg C rated wire is routed into the compartment through the removable 1/2 in conduit knockouts and connected to the factory wired terminal block.
