Rated for 690 V AC and 500 V DC, it handles motor feeder isolation, bus coupler duty, or DC load switching in control cabinets where a visible break is required. At 70 mm deep, 76.2 mm wide, and 130 mm tall, this 3-pole unit fits the standard 3VA1 frame footprint — same depth and width as the 100 A line-protection variant 3VA1010-2ED32-0JA0, so a panel laid out for that breaker accepts this switch disconnector without re-drilling or re-spacing.","metaTitle":"Siemens 3VA1112-1AA36-0HC0 SENTRON Switch Disconnector, 125","metaDescription":"Siemens 3VA1112-1AA36-0HC0 SENTRON switch disconnector, 125 A rated continuous current, 3-pole, IP40 front, shunt trip release.
