Siemens SENTRON 3VA2116-6HL32-0CH0 — 160 A MCCB with Undervoltage Release
The Siemens SENTRON 3VA2116-6HL32-0CH0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current, designed for line protection in distribution panels and industrial switchboards. It carries a breaking capacity of 242 kA at 240 V AC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V — so the interrupting rating you need to match against the available fault current at the installation point varies significantly with system voltage.
Key Ratings and What They Mean for Fit
The 160 A continuous rating holds across the full ambient temperature range from -25 °C to 70 °C — no derating curve to chase for standard panel environments. The 3-pole construction suits three-phase line protection; the unit is not fitted with ground-fault monitoring or communication functions, so it is a straightforward thermal-magnetic or electronic trip MCCB for feeder protection. Maximum power loss is 28 W at rated current — a figure to check against enclosure thermal rise if the panel is densely packed. Dimensions are 86 mm deep, 105 mm wide, 181 mm high, fitting standard MCCB mounting footprints in switchboards. The unit ships with an undervoltage release (UVR) and a 2-auxiliary-switch plus 1-trip-alarm-switch configuration — the UVR means the breaker trips if control voltage drops below the dropout threshold, which is typical for emergency-stop or undervoltage protection schemes. The auxiliary contacts provide status feedback for PLC or indication circuits.
Panel Integration and Deployment Context
As a SENTRON MCCB, it mounts into standard switchboard or panelboard cutouts with screw-clamp or plug-in connections depending on the base. The 105 mm width and 86 mm depth fit typical MCCB slots in distribution panels; verify the busbar or cable connection method against the panel's existing design.
