The Siemens SENTRON 3WL1216-4CB34-4AN2 is a fixed-mounted, 3-pole air circuit breaker designed for reliable protection and control in demanding low-voltage power distribution systems. Rated at 1600 A and suitable for IEC applications up to 690 V AC at 50/60 Hz, this circuit breaker is built for industrial and infrastructure environments where high breaking capacity and operational safety are essential.

This size II circuit breaker offers an ultimate short-circuit breaking capacity (Icu) of 100 kA at 500 V, ensuring dependable performance under fault conditions. It is equipped with front connections at both top and bottom using dual-hole terminals, enabling flexible integration into switchgear assemblies. The electronic overcurrent release ETU 25 with LSI protection provides adjustable settings from 0.4 to 1 x In, allowing precise coordination and system selectivity.

The operating mechanism supports both manual and motorized operation, featuring a spring charging motor for AC 208–240 V or DC 220–250 V. Activation is possible via AC 230 V or DC 220 V. The breaker includes a second auxiliary release with instantaneous undervoltage protection (F3) and 2 NO + 2 NC auxiliary contacts, supporting advanced monitoring and control functions.

As part of the Siemens SENTRON range, this circuit breaker reflects proven German engineering and high-quality manufacturing standards. Please note that this model is marked as obsolete, making it primarily suitable for replacement projects, system extensions, or maintaining installed bases where compatibility is required.
