1SAM340000R1003 ABB Control Manual Motor Protectors

ABB 1SAM340000R1003 is a protection unit designed with thermal-magnetic circuit breaker functionality for transformer primary protection. It features screw-clamp connections and offers an adjustable rated current ranging from 0.25A to 0.4A. The unit operates within an ambient air temperature range for operation of -25 to +70°C and for storage from -50 to +80°C. It is designed with an IP20 control voltage (DC), a rated impulse voltage (Uimp) of 6 kV, and a net width of 45 mm. This 3-pole (3P) protection unit provides short circuit protection, phase failure/loss, and transformer protection. It has a net depth of 86.75 mm, operates with a control voltage (AC), and has a rated insulation voltage (Ui) of 690 V. The unit is capable of 100,000 operations and features an ON/OFF/TRIP rotary knob for control. It mounts on DIN rails or mounting plates, supporting a primary current of 690 V and an operating mode of 100,000 operations. The angular positions offer thermal protection for overloads adjustable between 0.25A and 0.4A.
