ABB Electrical 1SCA022257R5950 Switch Disconnector

ABB Electrical 1SCA022257R5950 Switch Disconnector

Basic Parameters

Rated current: 160A.

Rated Voltage: Suitable for 400-415V voltage level, can meet the common voltage requirements of general industry and civil low voltage distribution system.

Number of poles: 3-pole switch, which can effectively cut off or connect the three-phase circuit and ensure the isolation and safe operation of three-phase electrical equipment.

Installation: base mounting or DIN rail mounting, flexible and convenient installation, according to different use scenarios and electrical equipment layout to choose the appropriate installation method, easy to integrate and install in the distribution cabinet and other equipment.

Functional features

Reliable isolation function: It is mainly used to reliably isolate the part that needs to be operated from the power supply when the electrical equipment is overhauled, maintained or malfunctioned, forming an obvious and visible disconnection point, preventing the power supply from being accidentally switched on, ensuring the safety of the maintenance personnel, and providing a strong guarantee for the safe maintenance and overhaul of the electrical equipment.

Convenient operation: With the front operation design, the operator can easily perform the opening and closing operations on the front side of the switch, and the operation mechanism is simple and easy to understand, easy to grasp. At the same time, the operating handle is ergonomically designed to save effort and enable precise operation control to ensure reliable switching.

High safety performance: Equipped with corresponding safety protection devices, such as padlockable handles, the padlock further prevents misoperation and ensures that the disconnectors are always kept in a safe breaking state during overhaul or maintenance, which greatly improves the safety and reliability of the equipment. In addition, the switches are equipped with a clear indication marking of the opening and closing of the gate, which enables the operator to visually confirm the state of the switches and avoid miscalculations.

Excellent mechanical performance: Adopting high-quality materials and advanced manufacturing process, the switch has high mechanical strength and stability, and can withstand frequent operation and long-term use. Under normal use conditions, it can ensure a long service life and reduce the equipment downtime and maintenance costs caused by mechanical failure.

Good electrical performance: it has good electrical insulation performance, which can effectively prevent the occurrence of leakage and short-circuit faults. Its rated insulation voltage and other parameters to meet the requirements of the relevant electrical standards, in different working voltages and environmental conditions, can be stable and reliable operation, to ensure the normal power supply of the power system and the safe operation of equipment.

Applications

Industrial field: Widely used in various industrial places, such as factories, mines, metallurgy, chemical industry and other low-voltage power distribution system, used for motor, transformer, distribution cabinets and other electrical equipment for isolation and protection. In the process of industrial production, when it is necessary to carry out overhaul, maintenance or troubleshooting of the equipment, the isolation switch can be used to reliably isolate the equipment from the power supply, guaranteeing the safety of the maintenance personnel, while not affecting the normal operation of other equipment.

Commercial buildings: In the electrical systems of commercial buildings, such as shopping centres, office buildings, hotels, etc., it can be used in the distribution circuits of lighting, air-conditioning, lifts and other equipment as a service switch. During the maintenance and overhaul of these equipments, it can reliably cut off the power supply to ensure the safety of maintenance work and improve the reliability and safety of the electrical system of commercial buildings.

In the field of electric power system: in substations, distribution rooms and other electric facilities, it can be used as a disconnecting switch on the low-voltage side, which is used to isolate different electric intervals or equipment, facilitate the overhaul and maintenance of the equipment, and improve the reliability and safety of the electric power system. In addition, in some small distributed power generation systems, such as solar photovoltaic power generation system, wind power generation system, etc., it can also be used for isolation and protection of the system to ensure the safe operation of power generation equipment and power grid.
