160 A MCCB with flat thermal derating and high interrupting capacity
The Siemens 3VA2116-6HL32-0AE0 is a SENTRON molded case circuit breaker rated for 160 A continuous current, holding that rating flat from 40 °C through 70 °C ambient — no derating needed across the typical panel environment. Three-pole construction with an adjustable thermal-magnetic trip range of 240 A minimum to 1 600 A maximum, making it suitable for feeder or main breaker duty in distribution panels where the load can be sized within that window. Interrupting capacity follows the voltage curve: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V — the 690 V figure is low enough that this breaker should not be the primary fault-clearing device on a 690 V bus unless upstream coordination is confirmed.
Configuration and integration notes
This variant ships without undervoltage release, ground-fault monitoring, communication module, or trip indicator — it is a bare line-protection MCCB. Four auxiliary switches (HQ type) are included for status feedback to the PLC or panel indication. Footprint is 105 mm wide by 86 mm deep by 181 mm tall — standard 3-pole MCCB envelope for DIN-rail or panel-mount installation. Rated insulation voltage is 800 V, so it can be applied on 480 V and 600 V class systems without voltage derating concerns. Maximum power loss of 25.5 W at rated current — account for this in enclosed panel thermal calculations, especially when grouping multiple breakers in a single enclosure.
Lifecycle and sourcing posture
Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. The storage minimum matters for unheated warehouses in cold climates — the breaker can sit at -40 °C without damage.
