ABB KXT1HTC-3 Safety Relay

ABB KXT1HTC-3 is a high-terminal insulating cover for the Tmax XT1 3-pole molded-case circuit-breaker family. As an HTC, it is designed to shield the exposed high-terminal connections on three-pole XT1 devices, reducing the risk of accidental contact during installation and maintenance. The part appears in ABB catalogs as KXT1HTC-3 and is also listed under the SACE Tmax XT accessory lineup (alternate catalog number 1SDA066664R1), confirming its role as a protective terminal cover for the XT1-3P configuration. This cover aligns with ABB’s line of insulating terminal covers that accompany the Tmax XT family, providing a dedicated enclosure for terminal connections on XT1 units. Ideal for panel builders and maintenance teams, the KXT1HTC-3 complements other XT1 accessories to ensure safe servicing in electrical distribution panels and control cabinets, while preserving the accessibility needed for wiring termination when servicing 3-pole XT1 breakers.
