Siemens 3RV1041-4KA10 Overview

The Siemens 3RV10414KA10 is a circuit breaker designed for motor protection. It belongs to the S3 size category and has a Class 10 A-release, with a range of 57 to 75 A. The short-circuit release is rated at 975 A and features screw terminals for easy installation. It has a standard switching capacity. These products are manufactured in Germany and are designed for Automotive, aerospace, power generation, and electronics usage. They come with a 2-year warranty from MRO Electric. We also carry Contactors from other manufacturers such as FANUC and Yaskawa.


As part of the SIRIUS product brand, the 3RV10414KA10 is designed as a circuit breaker for motor protection. It includes general technical data such as an auxiliary switch for additional functionality. The power loss for the rated value of the current is 38 W in the hot operating state, with 12.7 W per pole. It has a surge voltage resistance of 6,000 V and an IP20 protection class on the front, indicating limited protection against solid objects.

The circuit breaker is built to withstand mechanical stress, with a shock resistance of 25g/11 ms. The mechanical service life of the main contacts is typically 50,000 switching cycles, ensuring long-term durability. It has a continuous current rating of 75 A.

In terms of ambient conditions, the circuit breaker can be installed at altitudes of up to 2,000 m above sea level. It operates within an ambient temperature range of -20 to +60 °C during operation, and it can withstand storage and transport temperatures ranging from -50 to +80 °C.

The main circuit of the 3RV10414KA10 consists of three poles, and it features an adjustable current response value for the current-dependent overload release, ranging from 57 to 75 A. It is rated for an operating voltage of 690 V, with a maximum AC-3 rated value of 690 V. The operational current at AC-3 is 75 A, and the operating power at 400 V is 37 kW. The circuit breaker has a maximum operating frequency at AC-3 of 15 cycles per hour.

The auxiliary circuit of the 3RV10414KA10 does not include any CO (changeover) contacts for auxiliary functions. However, it does provide protection and monitoring functions such as phase failure detection. It is classified as a Class 10 trip class, indicating its response time in the event of a fault.


The circuit breaker has a thermomagnetic design for both the overcurrent release and the short-circuit release. It has a maximum breaking capacity for short-circuit current (Icu) of 100 kA at 240 V, 50 kA at 400 V, 8 kA at 500 V, and 5 kA at 690 V.


Installation and mounting of the 3RV10414KA10 can be done in any position, and it can be fastened using screw and snap-on mounting onto a standard 35 mm mounting rail according to DIN EN 50022. Its dimensions are 165 mm in height, 70 mm in width, and 174 mm in depth. When mounted side-by-side, it does not require any spacing at the back or sides.


The connections and terminals of the circuit breaker feature removable terminals for the auxiliary and control circuits. The main current circuit uses screw-type terminals with box terminals, while the auxiliary and control circuit also uses screw-type terminals. The electrical connectors for the main current circuit are located on the front side of the device.

The connectable conductor cross-sections for the main contacts include solid wires ranging from 2.5 to 16 mm², stranded wires ranging from 10 to 50 mm², and finely stranded wires with core end processing ranging from 2.5 to 35 mm² and 2.5 to 50 mm². For AWG cables, the main contacts can accommodate sizes ranging from 10 to 1 and 10 to 2.

In summary, the Siemens 3RV10414KA10 is a circuit breaker designed for motor protection. It offers reliable protection against overloads and short circuits in motor circuits. With its adjustable current response value and thermomagnetic design, it ensures efficient and safe operation. The 3RV10414KA10 provides a range of technical specifications, including power loss, surge voltage resistance, shock resistance, and mechanical service life. It is suitable for installation in various ambient conditions and can be mounted in any position. The circuit breaker features screw terminals, removable terminals for auxiliary and control circuits, and a compact design. With its robust construction and reliable performance, the Siemens 3RV10414KA10 is a trusted choice for motor protection applications.
