Siemens SBLBD N 600V 6P BQD BLB Circuit Breaker

Siemens SBLBD N is a 6-pole mounting strap kit for Siemens panelboards designed to secure BL and BQD frame circuit breakers in 600 V installations. This installation accessory is not a standalone breaker but enables correct mounting of the corresponding BL/BQD frames in modular panel assemblies, often in 3- or 6-pole configurations. The unit height is 3.75 inches (95 mm), and it is designed for panel types such as P5 when used with strap-and-cover plate assemblies (for example SBLBD paired with HBQDGFCP). In practice, it supports twin mounting in Siemens panel systems and is intended for 600 V distribution where six-pole BQD/BL breakers are used.
