Siemens Copper SENTRON 5ST Busbar 4 Phase 80A 400 V AC, 18 mm Pitch, MPN 5ST3715

The Siemens 5ST3715 Copper SENTRON 5ST 4 Phase Busbar is a premium electrical distribution accessory engineered for demanding installations. Combined with the SENTRON range, it is crafted from high-grade copper, offering exceptional conductivity, strength, and reliability in large-scale commercial and industrial power distribution systems. The busbar is designed specifically for 4-phase systems, allowing seamless integration with miniature circuit breakers to achieve precise control and efficient distribution of electrical power.

With an operational voltage rating of 400 V AC and a current rating of 80A, this busbar meets the requirements of heavy-duty installations. The fully insulated pin-type connection and 18 mm pitch spacing ensure secure and safe connections, while its cut-to-length bar simplifies installation and customization. Excellent accessibility for feeder cables allows for easy servicing and extended system flexibility.

The Siemens 5ST3715 is ideal for use in distribution boards, panelboards, switchgear, and industrial electrical panels. It is compatible with both 1-phase and 3-phase protective switches, particularly the Siemens 5SJ6 and 5SY series miniature circuit breakers. No additional connection terminal is needed for stranded connections up to 35 mm², supporting reliable operation and streamlined maintenance.

Industrial applications include commercial complexes, factories, power plants, utility substations, and large administrative buildings. The busbar is constructed for environments requiring robust short circuit protection - Type B and Type C characteristics ensure rapid response to overloads and inrush currents.

Compliant with EAC, CE, and UKCA standards, it also adheres to DIN 57606 and DIN 57659 norms. The busbar features lug spacing at 18 mm and is fully insulated for enhanced electrical safety. It provides pin connections for feeder cable management, and load capacity can be optimized by selecting cable cross-sections, such as 10 mm² for 50→90A or 16 mm² for 65→120A.

For buyers seeking reliability, efficient power distribution, and proven technical standards from Siemens, the Copper SENTRON 5ST busbar is an essential component for modern electrical installations.
