Siemens 3RH5921 - 1CA10 Product Introduction

I. Basic Information

Brand: SIEMENS, as a world-renowned electrical and electronic company, Siemens has always been known for its innovation and high quality. Its products are widely used in many fields such as industry, energy, and medical care.

Model: 3RH5921 - 1CA10, this model accurately locates the unique specifications and functional configuration of the product.

Origin: Guangzhou, Guangdong, China, relying on advanced production bases and strict quality control systems to ensure stable and reliable product quality.

Material: Made of high-quality materials, with good electrical insulation performance and mechanical strength, able to adapt to complex working environments, and ensure long-term stable operation.

II. Product Features

Contact Configuration: Equipped with 1 normally open (NO) contact. The normally open contact is in a disconnected state when no external signal is applied. When a control signal is input, the contact quickly closes to realize the conduction and control functions of the circuit. This simple and efficient contact configuration is suitable for a variety of control logic requirements, can accurately transmit signals, and ensure that the electrical system operates according to the predetermined process.

Wiring method: Screw terminals are used. The screw terminal connection method is easy to operate. You only need to tighten the screws with a screwdriver to firmly fix the wire on the terminal. This connection method has reliable contact and can effectively avoid poor contact caused by vibration, looseness, etc., to ensure the stability and safety of circuit connection. It is especially suitable for use in occasions with frequent vibration in industrial environments.

Applicable contactor: Designed specifically for 3RT1 series contactors, it has a high degree of compatibility and matching with 3RT1 series contactors. When used together, the two can perfectly fit the overall architecture of the electrical system, give full play to their respective performance advantages, achieve efficient and stable control and protection functions, and provide solid guarantees for the normal operation of loads such as motors.

Electrical parameters

Rated working voltage: It can withstand voltages up to 690VAC (AC) and 600VDC (DC), can adapt to electrical systems of different voltage levels, and is widely used in various industrial and civil scenarios. Whether it is the common 220V, 380V AC power supply or the DC power supply system in some special occasions, the auxiliary switch group can work stably.

Rated working current: Excellent performance in different application scenarios. For example, in the AC-12 application category, the rated working current can reach 10 amps; in the AC-14/AC-15 application category, it is 6 amps; in the DC-12/DC-13 application category, it can also reach 10 amps. These parameters mean that the product can reliably control circuits of different types and load sizes to meet diverse electrical control needs.

Protection level: Reach IP20 protection level. The IP20 protection level means that the product can protect against the entry of solid foreign objects with a diameter greater than 12.5mm, such as accidental touches such as fingers, effectively avoiding short circuits, faults and other problems caused by the entry of foreign objects, and ensuring the safety of products and personnel. At the same time, its protection design also helps to extend the service life of the product and improve the reliability of the product under normal use conditions.

Environmental adaptability: It can work normally in the ambient temperature range of -25℃ to 60℃. This wide temperature adaptability range makes it suitable for various climatic conditions and industrial environments. Whether it is the cold northern region, the hot southern factory, or the outdoor place with large temperature changes, it can operate stably to ensure that the electrical system is not affected by the ambient temperature and works continuously and reliably.

III. Application field

Industrial automation: In industrial automation production lines, this auxiliary switch group is often used to control the start, stop and forward and reverse rotation of the motor. For example, in the automated assembly line, by cooperating with electrical components such as contactors and relays, according to the signal sent by the control system, the running state of the motor is accurately controlled to realize the automated operation of the equipment and the precise control of the production process, thereby improving production efficiency and product quality.

Mechanical equipment manufacturing: It is widely used in electrical control systems of various mechanical equipment. For example, in machine tool equipment, the 3RH5921-1CA10 auxiliary switch group controls the motor to realize the precise control of various actions such as tool feeding and spindle rotation, ensuring that the machine tool can perform processing operations according to the predetermined program to meet the processing needs of different workpieces.

Power system: In the field of low-voltage power distribution of power systems, it can be used to monitor and control the on-off status of circuits. For example, in the distribution box, as an auxiliary control element, it cooperates with circuit breakers, contactors and other equipment to realize remote monitoring and automatic control of power distribution, ensure the safe and stable operation of the power system, timely detect and handle circuit faults, and improve the reliability of power supply.

Building electrical: In the electrical control system of buildings, it is often used in lighting systems, ventilation systems, elevator control systems, etc. For example, in intelligent lighting control systems, through the cooperation of the auxiliary switch group and the controller, the functions of timed switching and brightness adjustment of lighting fixtures are realized, and energy saving and intelligent management are realized; in elevator control systems, it participates in the operation control and safety protection of elevators to ensure the normal operation of elevators and the safety of passengers.
