ABB, Tmax XT, 1SDA06 Molded Case Circuit Breaker 3-Pole 85A, Breaking Capacity 85 kA, Fixed

This moulded case circuit breaker provides three-pole protection for industrial and commercial electrical installations, disconnecting circuits under overload or short-circuit conditions. It is intended for fixed mounting in distribution panels and controlgear, offering a Compact solution for managing three-phase power up to high voltage levels in automation and electrical systems.

• 85A continuous current rating for steady operational loads • 85kA fault interruption capacity to limit system damage • Rated for 690V AC operation across three phases • 500V DC capability for mixed AC/DC installations • Front Terminal arrangement for straightforward wiring access • Lever reset actuator enabling quick manual reclosure

• Suitable for protecting three-phase motor feeders in factories • Ideal for distribution boards in process automation plants • Used with control panels requiring AC and DC compatibility • Can be used for switchgear in electrical maintenance fleets • Suitable for retrofit in Tmax XT range-compatible systems

It is designed for fixed mounting and should be secured to the panel or enclosure busbar arrangement specified by the switchgear manufacturer.

Front terminals permit access from the panel face, simplifying connection and removal of supply and load conductors during installation and service.

The device is manufactured to recognised CE, IEC and RoHS standards, indicating conformity with applicable safety and material directives.

The breaker occupies a moderate footprint with a width of 105mm and a depth of 82.5mm, allowing calculation of panel real estate and clearance requirements.
