FAQ for G3NB-225B-1

Is G3NB-225B-1 suitable for inductive loads?
It is primarily selected for resistive loads; inductive applications require additional protection and verification of relay characteristics.
What is the benefit of SSR for high switching frequency?
SSR operation avoids mechanical contact wear and bounce, allowing consistent performance under frequent switching.
Can I use it in temperature controllers output stage?
Yes, this is a common integration pattern for driving heater circuits from PID or PLC control outputs.
Do I need thermal management?
Yes. Current level and ambient temperature determine heatsink requirements for reliable continuous operation.
