Key ratings and what they mean for fit
The Siemens SENTRON 3VA2116-6HL32-0DA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current Iu of 160 A at ambient temperatures up to 50 °C — meaning it can carry full load without derating in a typical 40 °C panel, and only begins to step down above 55 °C (154 A at 55 °C, 148 A at 60 °C, 142 A at 65 °C, 136 A at 70 °C). Breaking capacity hits 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 5 kA at 690 V — these are the maximum fault currents the breaker can safely interrupt at each voltage level, critical for confirming SCCR compliance in high-fault panels like transformer secondaries or large motor control centers. Rated insulation voltage Ui is 800 V, and the operating temperature range spans -25 °C to 70 °C, with storage from -40 °C to 80 °C — the storage limits govern handling during transport, not running conditions.
Lifecycle and sourcing posture
Lifecycle stage is marked as current — meaning this is an active, in-production part from Siemens. No phase-out or last-time-buy notice applies. The part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
Panel integration and mechanical fit
Dimensions: 105 mm wide, 181 mm high, 86 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures. The 105 mm width is the critical dimension for multi-breaker lineup spacing; verify busbar and phase barrier clearance before committing the panel layout. Maximum power loss is 28 W — a modest thermal load for a 160 A breaker, but if multiple units are ganged in a sealed enclosure, factor the cumulative heat into the cabinet cooling budget.
