(Avoid icing and condensation)

Unit weight

Single type: approx. 5 g, Twin type: approx. 9.5 g

Notes: *1.Depends on connection conditions. Also, this does not guarantee repeated switching. We recommend that you confirm operation under actual conditions.

*2.This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the actual load.

*3.The upper operation ambient temperature limit is the maximum temperature that can satisfy the coil temperature rise value. For details, please refer to the “Automotive

Relay Users Guide”.

Please inquire our sales representative if you will be using the relay in a high temperature atmosphere (110°C).

*4.Part numbers for electric discharge lamp loads or any other lamp loads and for capacitor loads only consist of “ACTB*L**”.

When using the lamp control type, connect N.O. to the “+ (plus)” side. Please inquire our sales representative for details.

* If the relay is used continuously for long periods of time with coils on both sides in an energized condition, breakdown might occur due to abnormal heating depending on the

carrying condition. Therefore, please inquire our sales representative when using with a circuit that causes an energized condition on both sides simultaneously.
