The Siemens 3RV2031-4EB10 circuit breaker is an electrical device for motor overload and short-circuit protection.
With a structure size of S2 (55mm wide), its rated current (AC-3) is 32A, current setting range is 27 - 32A, breaking capacity Icu (KA) is 65kA. The tripping device type is B, with 3 poles and no auxiliary contacts. It uses screw terminals. The mechanical and electrical life vary according to different current specifications: at 52A, both are 50,000 times; at 80A, both are 20,000 times. The maximum frame-level rated current is 80A.
As a motor protection component, it can promptly cut off the circuit when the motor encounters abnormalities such as overload or short-circuit, protecting the motor from damage. With Siemens' reliable technology and exquisite craftsmanship, this circuit breaker has stable performance and is widely used in the industrial field to ensure the safe operation of motors.
