- Description
The ABB 1SDA073877R1 is a kit of 4 phase-separation barriers, 100 mm high, for fixed-mounting SACE Emax 2 E1.2/3 and Tmax XT7/XT7M 3-pole air circuit breakers, inserted between poles to raise the internal clearance and creepage distance between phases. It is sized for the low (lower-terminal) position on a 3-pole fixed breaker.

Selection Notes
These low partitions sit between the breaker poles on the terminal side, raising phase-to-phase clearance where the installation or local wiring rules call for extra segregation beyond the breaker's standard pole spacing. The H=100 mm height and 4-piece kit size are specific to the 3-pole fixed E1.2/3-XT7-XT7M mounting; a 4-pole breaker needs a different kit count. Fit it at commissioning rather than retrofitting live, since the barriers mount directly against the pole housings.
