Siemens Sentron VL160X 20A 3-Pole Circuit Breaker (3VL1702-1DD36-0AA0)
The Siemens VL160X (Part Number: 3VL1702-1DD36-0AA0) is a 3-pole Molded Case Circuit Breaker (MCCB) engineered for primary plant, line, and feeder system protection. Designed within the proven Sentron 3VL family, the VL160X frame delivers high interrupting capacity in an exceptionally compact footprint.
Rated for a nominal continuous current of 20 Amperes at a calibration baseline of 50°C, this unit incorporates a thermal-magnetic trip unit (TM, LI function) featuring an adjustable inverse-time thermal overload release and a fixed instantaneous magnetic trip release. Built with a standard “N” breaking capacity rating, it clears severe short-circuit currents up to 55 kA at 415 V AC (IEC 60947-2). Its ruggedized mechanical architecture, high vibration tolerance, and multi-voltage ratings make it a reliable choice for marine switchboards, motor control centers (MCC), sub-distribution panels, and offshore marine engineering plants.
