Core Product Advantages and Features
S3 Framework Design
Adopting the SIRIUS S3 frame specification, the structure is robust and suitable for the protection needs of high-current motor circuits.
Current adjustment range 45-63A
The rotary dial can be set within the range of 45 to 63A, corresponding to the motor's rated current for precise overload protection.
Class 10 overload characteristics
It is designed to meet IEC overload protection Class 10 standards, balancing general motor starting characteristics with protection sensitivity.
Auxiliary contact 1NO+1NC
It has one set of normally open and one set of normally closed auxiliary contacts built in, which facilitates feedback of the motor's operating status to the control circuit.
