Siemens Braking resistor

Siemens Digital Industry Brake Resistor JJY:023434020002. Manufacturer: Siemens Digital Industry. Description: Brake resistor 21.00 Ohm, Type: JJY:023434020002. Type of accessory/replacement part: Brake resistor. Additional details: Brake resistor for power modules PM240-2 FSE P_MAX=55kW/12S/5% ED R=21 Ohm P_CONTINUOUS=2750W. Accessory for frequency converter brake resistor for the Power Module PM240-2 for the modular frequency converter SINAMICS G120. The brake resistors dissipate the excess energy from the intermediate circuit. They are intended for use with the Power Modules PM240-2 and PM240 (mounted on the side next to the Power Modules), which have an integrated brake chopper and cannot feed back generated energy into the grid. For regenerative operation, such as braking a flywheel with a large moment of inertia, a brake resistor must be connected to convert the generated energy into heat. For the Power Module sizes FSD to FSGX, the brake resistors should be placed outside the control cabinet or outside the switchgear room to dissipate the generated waste heat from the area of the Power Modules. This reduces the air conditioning effort. Each brake resistor is equipped with a temperature switch. To avoid consequential damage in the event of thermal overload of the brake resistor, the temperature switch should be monitored. The brake resistor is available for sizes FSA to FSC as well as for the Power Module PM240-2 (size FSC to FSF). For size FSGX, there is an optional plug-in braking module. SINAMICS - simply my drive.
