Product Description:
The 175U3014 brake resistor is manufactured by Danfoss as part of the VLT Brake Resistors series. It connects to the DC link of a VLT drive so that kinetic energy from a decelerating motor is converted into heat instead of raising the bus voltage. By providing controlled energy dissipation, the component helps protect drives that regulate conveyors, elevators, or pump systems in general industrial automation.
The resistor’s continuous thermal load capacity is 280 W, meaning it can absorb that amount of power continuously without exceeding its base temperature rating. For short braking events, it supports a pulse load of 2.8 kW at a 10% duty cycle, giving drives additional capacity during emergency stops. A fixed resistance of 145 Ω sets the current that flows from the DC bus, and the enclosure is rated IP21, allowing installation inside protected control panels with limited exposure to dripping water or accidental contact. The extruded housing measures 160 mm in length, so it fits beside compact microdrives. A normally closed temperature switch mounted on the core opens the circuit if internal heat rises excessively. The switch can be wired with 4 mm² conductors, while the main power terminals accept cables with cross-sectional areas up to 16 mm².
During repetitive deceleration sequences, the device can handle 0.7 kW at a 40% duty cycle, balancing mass and surface area against cabinet space constraints. The aluminum body weighs 1.3 kg, minimizing the added load on DIN rails or bulkhead plates. Thermal protection is triggered at 180 °C, and the normally closed contact is rated for control circuits up to 250 V AC at 2 A. The temperature switch can interrupt the control circuit when excessive heat is detected, allowing the connected drive or relay logic to respond to an overtemperature condition.
