£45.29
The TE Connectivity 1SNA115333R1000 is an MB10/10.L8 grey distribution terminal block assembly from the established Entrelec SNA screw terminal range. Designed for organised electrical distribution in industrial control panels, switchgear and automation equipment, it provides a factory-configured solution for distributing a common potential across multiple connection points.
The MB10/10.L8 is an eight-block interconnected distribution assembly using proven screw-clamp connection technology. By providing a ready-made interconnected terminal arrangement, it can simplify panel construction compared with assembling and bridging individual terminals on site, while maintaining accessible screw connections for installation, testing and maintenance.
With a 10 mm² IEC cross-section, 63 A IEC rated current and compact 10 mm terminal spacing, the 1SNA115333R1000 is designed for dependable industrial power and control distribution. The complete L8 assembly measures 82.5 mm wide and can be installed on G32, TH35-7.5 or TH35-15 mounting rails.
Distribution terminal assemblies provide a practical way to distribute a common electrical potential across several connection points while keeping panel wiring organised and serviceable. The MB10/10.L8 uses eight interconnected terminal blocks in a factory-configured assembly, reducing the need to select and install separate bridging components for an equivalent distribution arrangement.
The MB10/10.L8 combines a 63 A IEC rating with screw-clamp connections and support for common G32 and TH35 rail formats. Its modular SNA construction makes it suitable for panel builders, machine manufacturers and maintenance engineers requiring an established Entrelec distribution solution in industrial electrical systems.
