Product Positioning
The Siemens SIRIUS 3RV2021-4AA15 is an S0-size three-pole motor starter protector with a current adjustment range of 10~16A and comes pre-installed with front auxiliary contacts for easy and quick assembly line setup.
Core Product Advantages and Features
10~16A overload adjustable range
The thermal-magnetic trip design allows the overload current to be adjusted within the range of 10~16A, precisely corresponding to the motor's rated current and reducing the chance of false tripping.
Pre-installed front auxiliary contacts
The 3RV2901-1E pre-amplifier switch (1NO+1NC) is pre-installed at the factory, eliminating the need to purchase an additional installation kit. It can be directly connected in series with the control circuit signal.
High breaking capacity of 55kA at 400V
The rated short-circuit breaking capacity is 55kA at 400V (Ics 25kA), providing the short-circuit protection level required for industrial power distribution applications.
Phase loss detection protection
It has a three-phase phase loss sensing function, which can trip immediately when any phase current is abnormally missing, protecting the motor from the risk of single-phase burnout.
UL Type E Self-Protection Certification
It meets the UL self-protection modular motor controller (Type E) certification requirements and simplifies the motor circuit type testing process.
