Siemens SENTRON Copper 3 Phase Busbar, 400 V AC, 80A, 18 mm Pitch, Pin Connection 5ST3710

The Siemens SENTRON 5ST3710 is a copper 3 phase busbar engineered for reliable power distribution in industrial and commercial electrical circuits. Designed to operate at a rated voltage of 400 V AC, this busbar is ideal for supporting 3-pole miniature circuit breaker installations, ensuring safe and efficient current handling in distribution boards and panel systems.

Manufactured from high-purity copper, the busbar provides superior electrical conductivity, minimal resistance, and optimized performance for both continuous and peak load applications. With an 18 mm pitch and pin-type connection system, it allows for flexible, modular, and secure fitment in a range of panel architectures, enabling easy cut-to-length customization for both single-phase and three-phase protective switch configurations, including integration with Siemens series 5SJ6 and 5SY switches.

The 3-phase design offers enhanced load balancing, supporting current ratings up to 80A, which meets the demands of commercial and light industrial distribution boards. Lug spacing is maintained at 18 mm to provide uniform connection points, while full insulation options promote safety and reduce risk of accidental contact during installation or maintenance.

Notably, this busbar requires no additional connection terminals for stranded cables up to 35 mm², improving accessibility for feeder cables and minimizing assembly time. With robust construction and compliance with CE, UKCA, and EAC standards, the SENTRON 5ST3710 ensures reliable operation in diverse industrial environments.

Application scenarios include distribution boards in manufacturing, commercial buildings, HVAC systems, and laboratory power panels. The type B and C short circuit response characteristics provide adaptable protection to circuits ranging from lighting and heating loads (moderate inrush) to motor control and industrial fluorescent installations (higher inrush currents).

Rated voltage of 400 V AC for universal panel compatibility. 80A current rating ensures high-load support. Pin type connection and modular design reduce installation effort. High conductivity copper construction optimizes energy transfer.

18 mm pitch and lug spacing make for flexible integration. No need for extra terminals up to 35 mm² stranded cables.
