ABB 3-Pole DIN Rail Non-Fused Isolator Switch, 40A, 560kW, IP20 OT40F3 1SCA104902R1001

ABB OT40F3 1SCA104902R1001 3-Pole DIN Rail Non-Fused Isolator Switch is designed for industrial electrical systems requiring safe disconnection and circuit isolation. This isolator switch allows users to disconnect power by turning the switch to the off position, preventing current flow for maintenance or emergency operations.

The device features a compact footprint with dimensions of 68 mm (length) by 56 mm (depth) and 35 mm (width), making it suitable for installation in confined switchboards and motor control centers. It is engineered for a 3-phase electrical system with a high switching current rating of 40A and a switching power capacity of 560kW. The IP20 rating protects against accidental contact with live parts and ingress of solid objects above 12 mm, enhancing user safety in industrial environments.

Manufactured to meet UL and IEC standards, this ABB isolator switch assures quality and reliability. It includes a red handle for clear indication of switch status and utilizes screw terminals to ensure robust electrical connections. Installation is quick and secure via DIN rail mounting, with alternative screw hole mounting available for horizontal or vertical surfaces.

Rated for AC switching at 600V and DC switching at 1000V, it can accommodate varied power system requirements. Its maximum operating temperature is 40°C, ensuring performance stability in industrial enclosures with moderate ambient heat.

The isolator switch finds applications in motor control centers, industrial switchboards, and automation systems to isolate power parts safely for maintenance. Compared to fused isolator switches, it requires less maintenance as no fuse replacement is necessary, reducing downtime and operational costs.

The device supports a 3-pole configuration for three-phase electrical systems. Rated at 40 amperes with a switching power of 560kW for heavy-duty use. IP20 rated enclosure provides protection against solid objects greater than 12mm and touch safety.

Compact design with dimensions of 68 x 56 x 35 mm for space-efficient installation. Equipped with a red handle for clear operational visibility and screw terminal type for secure wiring. Suitable for mounting on DIN rails with optional screw hole mounting for versatility.

Operates within a temperature range up to 40°C, rated for AC 600V and DC 1000V switching voltages. Compliance with UL and IEC standards ensures quality and safety. Ideal for isolating power circuits in motor control centres, switchboards, and industrial automation.
