The Siemens SENTRON 3VA2116-5JQ32-0KA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, with a full-scale current of 160 A and a maximum breaking capacity of 1 600 A. It delivers 187 kA interrupting capacity at 240 V, dropping to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — so the available fault current at the panelboard determines which voltage rating governs the installation. The breaker carries its full 160 A continuously from 40 °C through 70 °C without derating, which simplifies panel sizing in warm enclosures.
Dimensions and integration
The breaker occupies 105 mm width, 181 mm height, and 86 mm depth — a 3-pole MCCB footprint that fits standard Siemens SENTRON panelboard mounting. The 86 mm depth leaves clearance for rear-connected busbars and wiring gutters in a typical 200 mm deep enclosure.
Auxiliary and protection features
This variant includes a shunt trip (STL) auxiliary release for remote tripping, and a voltage trigger for undervoltage or overvoltage detection. Ground-fault monitoring uses summation current formation on the L-conductor. No undervoltage release is fitted. Communication function is present, enabling integration with higher-level monitoring systems. Maximum power loss is 25.5 W — account for this in thermal calculations for a sealed or high-fill panel.
