ABB 3HAC0977-1 Resistor 10 Ohm 50W

1、 Product Overview

ABB 3HAC0977-1 is a high-power fixed resistor designed specifically for industrial automation systems and is a core component of ABB's industrial control product line. Its rated resistance is 10 Ω, with a power capacity of 50W. It adopts aluminum shell packaging and forced heat dissipation design, suitable for harsh environments with high loads and continuous operation. This product is mainly used in scenarios such as energy absorption, braking control, load testing, and circuit protection. It is commonly found in robots, servo drives, elevator control systems, and industrial power supplies.

Certified CE, UL, RoHS


Core functions

energy absorption

Used for energy release during servo motor or robot braking to prevent voltage spikes from damaging the drive. For example, in an elevator control system, when the motor stops, regenerative energy is consumed through this resistor to achieve smooth braking.

Current limiting and voltage divider

As a current limiting component in power circuits to protect sensitive electronic devices; Or provide precise voltage ratios in the voltage divider circuit to ensure stable control signals.

Load Testing

As a dummy load used for performance testing of power sources or inverters, it simulates power consumption under real working conditions.

EMC filtering

Combined with capacitors to form an RC filtering network, it suppresses high-frequency interference and improves the system's anti-interference ability.


Working principle

This resistor operates based on Joule's law: when current passes through the resistor, electrical energy is converted into thermal energy(P=I two×R). 

The aluminum shell packaging design achieves efficient heat dissipation through the following methods:

Material characteristics: The thermal conductivity of aluminum is as high as 237W/(m · K), which can quickly conduct heat from the resistance wire to the shell.

Structural design: The shell surface usually has heat dissipation fins to increase the heat dissipation area; Internally filled with thermal conductive silicone to reduce thermal resistance.

Thermal management: When the temperature exceeds the rated value, the power automatically decreases to ensure safe operation.


Key advantages

high reliability

Adopting winding technology, it has strong resistance to impact current (up to 3 times the rated current), and MTBF (mean time between failures) exceeds 100000 hours.

Precision control

The low temperature coefficient (± 200ppm/° C) ensures stable resistance over a wide temperature range, making it suitable for precision control circuits.

Compactness

The volume is 20% smaller than similar products, with high power density, saving control cabinet space.

Easy to integrate

Support standard rail installation, compatible with ABB and third-party control systems, reducing installation costs.
