What this MCCB does and where it fits
The Siemens 3VA2116-5HL32-0CH0 is a SENTRON molded case circuit breaker (MCCB) rated for 160 A continuous current, with a 3-pole configuration and a line-protection design. Its breaking capacity hits 187 kA at 240 V AC and 121 kA at 415 V and 440 V, tapering to 75.6 kA at 500 V and 3.7 kA at 690 V — so it handles high-fault scenarios typical in industrial distribution panels feeding motor control centers or heavy machinery. The 160 A rating holds flat from 40 °C through 70 °C, meaning no derating is needed in a warm enclosure. An undervoltage release (UVR) is built in, and the auxiliary switch complement includes two auxiliary switches plus one trip alarm switch (HQ).
Panel fit and dimensions
The 3VA2116-5HL32-0CH0 measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard SENTRON 3VA footprint that drops into existing MCCB panel cutouts without rewiring if the previous breaker was a 3VA2 series unit. The 3-pole block occupies three module widths on a DIN rail or direct-mount backplate.
