Product datasheet Performance Curves 

## RSB1A120BD 

## Electrical Durability of Contacts 

Durability (inductive load) = durability (resistive load) x reduction coefficient. Resistive AC load 

- X Switching capacity (kVA) 

- Y Durability (Number of operating cycles) 

Reduction coefficient for inductive AC load (depending on power factor cos ϕ) 

## Y Reduction coefficient (A) 

Maximum switching capacity on resistive DC load 

- X Voltage DC Y Current DC 

Note :  These are typical curves, actual durability depends on load, environment, duty cycle, etc.
