Product Description:
The 175U3049 from Danfoss’ VLT Brake Resistors lineup offers resistance of 19 Ω which controls discharge current and sets braking torque for kinetic energy dissipation. Its continuous power of 2200 W indicates the resistor’s steady-state dissipation capability and guides thermal mounting and ventilation requirements. Pulse load power (10% duty) values 27.3 kW defines short burst energy absorption and permits sizing for frequent brief braking cycles.
Also, the pulse load power (40% duty) is 6.8 kW establishes mid-duty pulse capability and informs duty cycle planning for repeated stops. Temperature switch is included and provides automatic thermal protection and enables safe shutdown on overtemperature. Terminal max wire cross-section 4.0 mm² (12 AWG) determines allowable terminal conductor size and supports secure connections. The power cable cross-section 16 mm² (6 AWG) sets the minimum power feeder size and supports rated current without overheating. It features the temp. switch cable cross-section 4.0 mm² (12 AWG) and that prescribes the control wiring gauge for reliable sensor signaling.
The number of temp. switches id “1” and can specify the single thermal cutout and simplifies wiring and monitoring. This module with minimum enclosure protection of IP20 restricts installation to cabinet mounting with basic access protection. This brake resistor 175U3049 also carries temp. switch type NC, 2 A, 250 V AC (aluminum-housed) to define switch ratings for safe thermal circuit interruption. Panel mounting is the drive’s mechanical attachment method. These compatible Danfoss VLT drives indicate matching for VLT braking circuits. Its weight is approx.11 kg and supports lifting and mounting calculations.
Frequently Asked Questions about 175U3049:
Q: What continuous dissipation rating applies to 175U3049?
A: The continuous power of 2200 W rating defines steady thermal load the resistor can dissipate indefinitely with proper cooling.
Q: How is the short duty pulse rating specified for 175U3049?
A: The drive’s pulse load power (10% duty) of the 27.3 kW figure represents peak energy absorption capability during short bursts and it helps size braking sequences.
Q: What intermediate pulse capability is provided by 175U3049?
A: This pulse load power (40% duty) of 6.8 kW value supports longer pulse intervals and informs permissible braking frequency under heavier duty cycles.
Q: Does 175U3049 include temperature monitoring?
A: Yes. A temperature switch can simply provide automatic detection of excessive resistor temperature and initiates protective actions.
Q: What terminal conductor size should be used with 175U3049?
A: The terminal conductor of 4.0 mm² (12 AWG) limit ensures secure termination and acceptable voltage drop at control wiring points.
