What is the ABB SHD202/40 switch disconnector used for?
The ABB SHD202/40 is a 2-pole, 40A switch disconnector designed for isolating and manually switching electrical circuits. It supports both AC (up to 415 V) and DC (up to 125 V) systems, commonly used in control panels, distribution boards, and machinery circuits for maintenance and safety isolation.
What are the electrical ratings of the ABB SHD202/40?
It has a rated current of 40 A and operates up to 415 V AC or 125 V DC. The rated conditional short-circuit current (Inc) is 10 kA, and the rated impulse withstand voltage (Uimp) is 4 kV at 2000 m altitude or 5 kV at sea level. It functions at 50/60 Hz frequency and supports overvoltage category III.
What utilization categories does the SHD202/40 comply with?
The device meets AC-22A and DC-21A utilization categories. This means it is suitable for switching mixed resistive and inductive loads, including moderate overloads, and for frequent actuation in both AC and DC circuits.
What are the endurance ratings of the ABB SHD202/40?
It offers an electrical endurance of 10,000 AC cycles and a mechanical endurance of 20,000 operations, ensuring long service life in industrial and commercial applications.
What type of terminals and cable connections does it support?
The SHD202/40 uses screw-type cable clamp terminals. It accepts flexible conductors of 0.75 – 16 mm² and rigid or stranded conductors up to 25 mm². The recommended tightening torque is 2 N·m using a Pozidriv 2 screwdriver.
What are the installation and mounting features?
It has a compact modular width of 2 modules (35 mm) with dimensions 85 mm × 69 mm × 35 mm (H×D×W). It can be mounted in any position and uses a toggle-type red actuator marked “I/O,” with a grey insulated housing (RAL 7035).
What are the insulation and material properties of the switch?
The actuator is made of insulation group II material, while the housing is insulation group I, ensuring safe isolation and mechanical strength. It is sealable and designed for reliable operation under industrial conditions.
Does the ABB SHD202/40 have any accessories or covers?
No additional accessories or covers are available for this model. It is supplied as a complete enclosed switch unit ready for DIN-rail mounting.
Where can I buy the ABB SHD202/40 in India?
