⚡ Function in the Electrical System
A 15 Ω / 100 W resistor is used for the controlled limitation and dissipation of electrical current and energy.
Depending on the circuit in which it is installed, it may perform various functions, including:
- Current limiting
- Electrical energy dissipation
- Discharge and braking circuits
- Damping of transients and oscillations
- Inrush current limitation
- Protection and control circuits
-
Power electronics applications
The exact function depends on the design of the equipment in which the resistor is installed.
🏭 Construction & Installation
The component features an elongated metal body with a finned surface, designed to facilitate the dissipation of heat generated during operation.
Thermal dissipation is particularly important for a 100 W resistor, as a significant portion of the electrical energy is converted into heat.
During installation, adequate heat dissipation must therefore be ensured. Direct contact with heat-sensitive materials should be avoided, and the clearances specified by the original equipment should be respected.
The existing wires should be checked for insulation, mechanical integrity, and connection quality before reuse.
🌐 Applications
The REOHM BW154/100/15/S may be used as a replacement component in:
- Inverters and power converters
- Industrial drive systems
- Industrial electronic equipment
- Braking and energy dissipation circuits
- Power supplies and conversion systems
- Current-limiting circuits
- Protection and damping systems
- Industrial automation equipment
Replacement should be carried out by verifying that the 15 Ω, 100 W ratings and the mechanical characteristics correspond to the original component.

🛡️ Safety & Product Condition
⚠️ During operation, a 100 W resistor can reach high temperatures. It must therefore be installed in conditions that provide adequate ventilation and heat dissipation.
The component is used and shows cosmetic signs consistent with previous installation. The electrical condition of the resistive element cannot be determined with certainty from the photographs alone.
Before recommissioning, it is recommended to perform a resistance measurement, verifying that the value is consistent with the nominal 15 Ω, as well as checking the insulation and integrity of the connection wires.
