3RH1 SIRIUS contactor relay is a switch device used for control circuits and auxiliary circuits, which can be used to control, provide signals, and interlock switch devices and switch screens. Undoubtedly, this contactor type relay has standard designated connections, which are both time-saving and cost-effective, meeting on-site needs. The 3RH1 SIRIUS contactor relay and the S00 sized motor contactor are of the same specification and have the same external design. This means great advantages, especially when using attachments.

This contactor type relay can be used for AC and DC control, and adopts a screw or cage type connection system. The basic model has 4-pole contacts, but can be extended to 8-pole contacts through a snap on auxiliary contact set.

The 3RT10 three pole contactor is best suited for one of the most common applications: switching three-phase motors. 7 specifications, covering power range from 3 to 250 kW/400 V, with AC and DC control. For electrical applications with extremely high service life requirements, heavy-duty starting, and 1000 V applications, 3RT12 contactor is your first choice.

The SIRIUS 3RT contactor comes in three specifications: S6, S10, and S12, providing unprecedented flexibility: the coils in the installed contactor can be replaced without the need for tools or removal of the main wiring.
The contactor coil can use conventional UC coils, electronic coils with/without remaining life indication or AS communication interface, and air and vacuum contactors can be used interchangeably.
SIRIUS overload relay has two options: thermal sensitive and electronic, which can be used in demanding applications to provide current overload protection for loads (such as motors) in the main circuit and switching and protection devices in the load feeding device.
Due to the harmonious correspondence between overload relays and other components of SIRIUS modular systems (contactors, soft starters, etc.) in terms of electrical, mechanical, and external design, SIRIUS overload relays can be used to configure compact load feeding devices, which are very simple and space saving.
The modular SIRIUS system also includes standard accessories that are size independent and can be adapted to 3RU11 thermal overload relays and 3RB10 electronic overload relays. Greatly simplified engineering design and reduced inventory costs.

1�� Characteristics of HSM1 series circuit breakers

The main technical performance of HSM1 series plastic shell circuit breakers has reached the international level of the 1990s. It has the characteristics of compact structure, small size, high short-circuit breaking capacity, no arcing, modular installation of internal accessory devices, enhanced safety with terminal protective covers, and different colors for the "base" and "cover plate" to enhance aesthetics.
The moving and stationary contacts and contact rods (connecting plates) of this series of circuit breakers are designed in a parallel shape, fully utilizing the electric repulsion before the short-circuit current of the line reaches its maximum value, causing the moving and stationary contacts to be repelled and limiting the increase of arc current; In addition, aromatic insulation materials that can release gas under the scorching heat of the arc are installed around the static contact to absorb arc energy, cool the arc, shrink the arc column, and greatly reduce the backward spraying of the arc. At the same time, an arc extinguishing device with arc gas dissociation is used to achieve zero arc distance. The application of the above new technologies greatly improves the short-circuit breaking capacity of circuit breakers and reduces the volume of complete electrical equipment.
The modular insertion installation of auxiliary devices and the provision of protective covers for terminals make the use of circuit breakers safer and more reliable.

2�� Purpose and Scope of Application
