Enamelled wire resistor
The RSE is a wire resistance wound on a ceramic elliptical support coated with vitreous enamel with clamps beneath the coating. The purpose of the coating is to (1) ensure the mechanical protection of the wire, (2) allow a uniform heat distribution and (3) limit thermal expansion of the coils. The coating does not have an electrical insulation function. Vitreous enamel ensures total waterproofing of resistance. The RSE is available in the low inductance version; in this case, it is called RSEN; it is available with an adjustment slider; in this case, it is called RSER; and with a fixed intermediate socket, in this case, it is called RSEP. The latter cannot be purchased through e-commerce, please contact our sales department:

1. In what sectors is this resistance used?
The main areas of application are industrial automation, energy and railway sector.
2. For what types of applications is it used?
The product is used: as a dynamic terminating resistor, as a basic element in harmonic filter circuits as a charge and discharge capacitor resistance in RC as heating resistances for electrical or anti condensation panels.
1. What are the electrical specifications?
The RSE family has 4 models with power ratings from 31 W to 91 W and the ohmic value ranges between 4.3 Ω and 75 k Ω. The maximum voltage of use varies depending on the model.
2. What are the overload conditions?
The resistance can be overloaded with respect to its nominal power based on the working cycle (insertion and rest time). For duration pulse less than one second, the overload permissible also depends on the ohmic value. For non-repetitive pulses the relation is 5 times the nominal power for 10 seconds.
3. What is the temperature of the resistance?
The temperature of the resistance depends on the power that it will dissipate. Numerous factors influence the dissipation capacity; please consult our technical data sheet for detailed information. The graph of the data sheet on page 3 shows the relationship between the temperature on the resistance and the power applied for a heating element placed horizontally.
1. How must I install the product?
The resistance can be mounted with its SP3 with hole, SP1 with slot and SPD with spacer; in this regard, see the related products data sheet. For a better heat distribution we suggest mounting it horizontally. The terminals made in nickel-iron alloy enable electrical connection through tinning. On request (not to be purchased via e-commerce) it is possible to provide a male faston cable lead. If installed in a group we recommend keeping a distance between the resistances of at least 20 mm.
