The Siemens Sentron 3WT8 is a premier industrial-grade Air Circuit Breaker engineered to deliver absolute protection and long-term service reliability in low-voltage distribution switchgears. Built around a highly robust, space-saving Size II frame layout, this 3-Pole, 3200A powerhouse shields expensive equipment, industrial machinery, and electrical installations against damaging network spikes.

Equipped with a precision push-button manual mechanism and internal micro-tripping components, the 3WT8 provides seamless, sparks-free current isolation under heavy load demands. Perfect for critical infrastructure, large-scale factories, heavy marine vessels, and primary power panels, it sets the standard for safe power distribution.

High Load Capacity: Rated for 3200 Amp continuous current, designed for heavy industrial low-voltage power networks.
Reliable Circuit Protection: Advanced microprocessor-based ETU (Electronic Trip Unit) offering comprehensive protection against Overload (L), Short Circuit (S), and Instantaneous Faults.
High Breaking Capacity: Engineered with a robust short-circuit breaking performance (Icu = 55kA / 66kA at 500V AC) to handle severe fault loads safely.
Flexible Draw-Out Version: Complete with side rails and secondary terminal connections for safe, simple maintenance, inspection, and hot-swapping configurations.
Globally Certified: Fully compliant with trusted international standards, including IEC 60947-2 and GB 14048.2 . [1, 2]
