Why Choose the ABB 1SDA073858R1 PBC Pushbutton Protection?
The ABB 1SDA073858R1 is a genuine PBC pushbutton protection accessory designed for ABB SACE Emax 2 E2.2, E4.2 and E6.2 air circuit breakers. Identified as PBC Prot. Pushbuttons AP/CH E2.2...E6.2, it provides mechanical protection for the breaker opening and closing pushbuttons, helping restrict accidental or unauthorised manual operation.
Opening and closing pushbuttons provide direct control of an air circuit breaker, making controlled access important in switchboards where defined operating procedures are required. The PBC accessory protects these front-mounted controls while remaining integrated with the Emax 2 operating interface.
Designed specifically for ABB SACE Emax 2 E2.2 through E6.2 frames, the 1SDA073858R1 is suitable for industrial, commercial and infrastructure power distribution systems. Its dedicated ABB construction ensures mechanical compatibility with the intended circuit breaker platform and supports controlled switchgear operation.
