Safety Switch OTA600P3B (1SCA144287R1001)

ABB 1SCA144287R1001 — EMC safety switch, 3-p. 415V AC23 540A, 315kW. Mounted auxiliary contact: 2NO2NC. Aluminium enclosure. IP65. Black Pistol handle. Interlocked cover. Defeatable interlocking. The dye casted aluminum alloy (silumin) enclosure is extremely rigid, and well suited for harsh environment. The surface is polyester coated and well protected from corrosion. Installation is made easy, thanks to the key hole type wall fastening, screwed cover and the included rubber type cable glands. The enclosure is arc proof. The cover is interlocked, and the interlocking can be defeated if needed. There are two or four cable entries, and one cable entry for the control cable. The unit is also EMC type, and no additional EMC cable glands are needed. Earthing of the cable shield is done via the pullstopper. Neutral and PE terminals are included.
