3RU2126-4EC1
The Siemens SIRIUS 3RU2126-4EC1 thermal overload relay features an S0 frame, a current adjustment range of 27 to 32 amps, spring-loaded screwless terminals, and independent mounting, eliminating the need for direct mounting to the contactor and enabling quick wiring.
Product Positioning
The Siemens SIRIUS 3RU2126-4EC1 has a current adjustment range of 27 to 32 amps, uses spring-loaded (screwless) terminals, and is designed for independent mounting, not directly attached to the contactor, making wiring faster.
Core Product Advantages and Features
Spring-loaded quick-connect terminals
Both the main circuit and the auxiliary circuit use spring clip terminals, allowing for wiring connections without the need for screws.
Independent installation design
The non-contact front-mounted type can be fixed to the guide rail or base plate according to the configuration requirements of the control panel.
27-32A Adjustment Range
It covers applications of medium-current motors and meets the overload protection settings of common three-phase induction motors.
Class 10 protection features
It operates according to the IEC thermal overload action curve, taking into account both start-up tolerance and abnormal overload response.
