What this MCCB carries and where it fits
The Siemens SENTRON 3VA2116-5HL36-0AD0 is a 3-pole molded case circuit breaker (MCCB) sized for line protection in distribution panels. Its continuous current rating holds flat at 160 A from 40 °C all the way through 70 °C — no derating needed across the typical switchgear ambient range, which simplifies panel coordination in a warm enclosure. Breaking capacity is the headline: 187 kA at 240 VAC, 121 kA at 415 VAC and 440 VAC, 75.6 kA at 500 VAC, and 3.7 kA at 690 VAC. That 187 kA at 240 V means it can handle a high-fault utility feed or a large transformer secondary without upstream fuses — useful when you are retrofitting a panel with a stiff source and want to keep the existing buswork. Dimensions are 181 mm tall, 105 mm wide, 86 mm deep — a standard MCCB footprint that drops into most SENTRON panel mountings without re-drilling. Insulation voltage is rated 800 V, so it can be used in 690 V systems with headroom.
Sourcing and lifecycle
No ground-fault monitoring built in (specified as 'without'), and no undervoltage release or communication function on this variant. It carries three auxiliary switches (HQ type) for status feedback to a PLC or annunciator. Rated insulation voltage 800 V, operating temperature range -25 °C to 70 °C, storage from -40 °C to 80 °C. Max power loss at rated current is 25.5 W — relevant for thermal calculations in a sealed enclosure.
Panel fit and integration
Mounts on a standard DIN rail or panel-mount base in a SENTRON distribution board. The 105 mm width means it occupies three pole spaces. No voltage-trip or shunt-trip accessory on this variant — if you need remote tripping, you will add an external undervoltage release module (not included). The basic switch part number is 3VA21165HL360AA0, which is the internal mechanism; the auxiliary switch set is a 3-switch HQ block. If you are replacing an older 3VA1 frame, verify the auxiliary wiring — the HQ contact arrangement may differ from the previous generation.
