Siemens Copper SENTRON 3 Phase 63A Busbar, Rated Operational Voltage 400 V ac, 18 mm Pitch 5ST3740

Siemens 5ST3740 Copper SENTRON Busbar is a precision-engineered 3-phase busbar system designed for electrical power distribution in switchgear and distribution boards. Operating at a rated operational voltage of 400 V ac, it offers reliable current conduction with a current rating of 63A. Constructed from high-purity copper, this busbar ensures excellent electrical conductivity and durability in demanding industrial and commercial electrical setups.

The 5ST3740 busbar belongs to the SENTRON 5ST series, featuring an 18 mm pitch and lug spacing, facilitating efficient and neat connections in electrical panels. This design complies with EAC, UKCA, and CE standards, ensuring conformity with regional and international safety requirements.

Its cut-to-length design allows easy customization and installation, compatible with 1 or 3-phase line protective switches from series 5SJ6 and 5SY. The pin connection type minimizes the need for extra components, supporting stranded wires up to 35mm² without requiring additional terminals. The busbar ensures excellent accessibility for feeder cables, making maintenance and upgrades straightforward.

This busbar adapts to Type B characteristic circuit breakers providing instantaneous short circuit response suitable for circuits with moderate inrush currents, such as filament lamps and heating loads. It also supports Type C characteristic breakers suitable for circuits with higher inrush currents, including motor control and fluorescent lighting in industrial environments, preventing nuisance tripping.
