Question
What types of load are there (resistive loads, inductive loads, lamp and capacitor loads)?
Answer
The load types and their characteristics are as follows.
1. Resistive Loads
Nichrome heaters and other loads to which the same current continues to flow when voltage is applied
2. Inductive Loads
Motors, solenoids, and other loads with inrush current
3. Lamp and Capacitor Loads
Loads with inrush current even larger than with inductive loads
AC Loads and Inrush Current:
Type of load | Ratio of inrush current to steady-state current | Waveform | |
Solenoid | Approx. 10 | ||
Incandescent bulb | Approx. 10 to 15 | ||
Motor | Approx. 5 to 10 | ||
Relay | Approx. 2 to 3 | ||
Capacitor | Approx. 20 to 50 | ||
Resistive load | 1 |
DC Loads and Inrush Current:
Best-selling, general-purpose relays that can be selected based on operating environment and application
Power-switching Compact General-purpose Relays
Compact, Slim-profile SSRs with Heat Sinks. Solid State Contactors for Three-phase Heaters Reduced Installation Work with DIN Track Mounting.
