Siemens SENTRON 3VA2116-5HL32-0BA0 — 160 A MCCB with Undervoltage Release
The Siemens SENTRON 3VA2116-5HL32-0BA0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current, designed for line protection in distribution panels. Its 187 kA breaking capacity at 240 VAC means it can safely interrupt fault currents up to that level without cascading upstream — critical for high-fault installations like transformer secondaries or large motor control centers. The integrated undervoltage release (UVR) trips the breaker when supply voltage drops below a set threshold, protecting downstream equipment from brownout damage. Breaking capacity holds at 121 kA through 415–440 VAC and remains usable at 75.6 kA at 500 VAC, tapering to 3.7 kA at 690 VAC — a curve that suits 400 V class industrial distribution where most fault energy lands. Rated insulation voltage is 800 V, so the breaker is rated for 690 V systems with margin. Dimensions are 105 mm wide, 181 mm high, 86 mm deep — a standard 3-pole MCCB footprint that fits most Siemens SENTRON panelboards and switchgear without re-drilling. The 160 A rating holds flat from 40 °C through 70 °C ambient, so no derating is needed in warm enclosures.
Integration Notes
Mounts in standard SENTRON panelboard or switchgear cubicle — 105 mm width fits 3-pole MCCB cutouts. The undervoltage release coil draws power from the line side; ensure control voltage matches the UVR rating (not specified here — confirm from nameplate). No auxiliary contacts or shunt trip are included; add them via the accessory slot if needed. Operating temperature range is -25 °C to 70 °C; storage from -40 °C to 80 °C. Maximum power loss is 28 W at rated load — account for heat dissipation in enclosed panels.
