SENTRON 3VA2116-5HL36-0AJ0 — 160 A MCCB for Line Protection
The Siemens 3VA2116-5HL36-0AJ0 is a SENTRON molded case circuit breaker (MCCB) rated for 160 A continuous current, sized to protect main feeders or large branch circuits in industrial distribution panels. Its 3-pole design handles three-phase loads, and the line-protection trip curve (thermal-magnetic or electronic, depending on the internal trip unit) coordinates with downstream breakers to isolate faults without taking the entire panel down. Breaking capacity is the headline number here: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. That 187 kA at 240 V means this breaker can safely interrupt a fault current up to 187 000 A without welding contacts or rupturing the case — critical for high-fault locations like substation secondaries or large motor control centers where available fault current can exceed 100 kA. The 160 A rating holds flat across the full ambient temperature range from 40 °C to 70 °C — no derating needed up to 70 °C ambient, which simplifies panel layout in hot environments like foundries or boiler houses. Power loss at full load is 25.5 W, manageable for standard enclosure ventilation.
Panel Fit and Auxiliary Switching
Dimensions are 105 mm wide, 181 mm high, 86 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON panelboards and switchgear without re-drilling. The 86 mm depth (3.39 in) is shallow enough for shallow backpan enclosures; the 105 mm width (4.13 in) matches the typical 3-pole MCCB slot pitch. Factory-fitted auxiliary switch block carries 2 auxiliary switches plus 1 trip alarm switch (HP type), giving remote status of breaker position and fault trip without adding external relays. No undervoltage release or shunt trip is included (no voltage trigger), and no ground-fault monitoring — this is a straight line-protection breaker for non-GFCI applications.
