Altivar Soft Starter ATS480
Altivar Soft Starter ATS480 Soft starters for asynchronous motors Selection from ATS48 commercial reference, selection criteria
Selection criteria
From an ATS48 commercial reference ATS48 and ATS480 have the same commercial reference structure: b The product range e.g. ATS48 b The current rating e.g. C17 b The voltage e.g. Q (Q for 230/415 V or Y for 208/690 V) To select the ATS480 commercial reference corresponding to the ATS48 reference: 1 – Replace the ATS48 product range with ATS480 2 – Keep the same rating 3 – Always put Y to represent the operational voltage Examples:
ATS48 C17 Q
From
“480” instead of “48”
= always “Y”
ATS480 C17Y
To
b ATS48M12Q becomes ATS480M12Y b ATS48D62Y becomes ATS480D62Y
Selection criteria for Altivar Soft Starter ATS480 b The mains voltage b The rated motor power and rated motor current b The type of application: normal duty or heavy duty
Select normal duty or heavy duty application Examples of normal duty and heavy duty applications are given on page 14. Normal duty and heavy duty are differentiated by the required overload that is defined by the following: b Service duty: continuous or intermittent b Service factor b Overcurrent value b Overcurrent duration From an application standpoint, the overload is defined depending on the service duty of the motor - S1 (continuous operation) or S4 (intermittent operation) - according to the following table: Service type Overload (starting) Service cycle Overcurrent Duration No. of starts/h Conduction Normal duty S1 Continuous operations after starting
