C Circuit Design
A Load Circuits
C-A-1 Load Switching
In actual Relay operation, the switching capacity, electrical durability,
and applicable load will vary greatly with the type of load, the
ambient conditions, and the switching conditions. Confirm operation
under the actual conditions in which the Relay will be used.
A Resistive Loads and Inductive Loads
The switching power for an inductive load will be lower than the
switching power for a resistive load due to the influence of the
electromagnetic energy stored in the inductive load.
B Switching Voltage (Contact Voltage)
The switching power will be lower with DC loads than it will with AC
loads. Applying voltage or current between the contacts exceeding
the maximum values will result in the following:
1. The carbon generated by load switching will accumulate around
2. Contact deposits and locking will cause contacts to malfunction.
C Switching Current (Contact Current)
Current applied to contacts when they are open or closed will have a
large effect on the contacts. For example, when the load is a motor or
a lamp, the larger the inrush current, the greater the amount of
contact exhaustion and contact transfer will be, leading to deposits,
locking, and other factors causing the contacts to malfunction.
(Typical examples illustrating the relationship between load and
inrush current are given below.) If a current greater than the rated
current is applied and the load is from a DC power supply, the
connection and shorting of arcing contacts will result in the loss of
switching capability.

C-A-2 Electrical Durability
Electrical durability will greatly depend on factors such as the coil
drive circuit, type of load, switching frequency, switching phase, and
ambient atmosphere. Therefore be sure to check operation in the
actual application.
C-A-3 Failure Rates
The failure rates provided in this catalog are determined through
tests performed under specified conditions. The values are reference
values only. The values will depend on the operating frequency, the
ambient atmosphere, and the expected level of reliability of the
Relay. Be sure to check relay suitability under actual load conditions.
