It is configured for line protection — meaning it protects cables and busbars from overload and short-circuit, not motor or generator circuits. The ETU350 gives you adjustable long-time, short-time, and instantaneous pickup settings, plus ground-fault alarm capability (though this variant ships without ground-fault monitoring hardware). Breaking capacity is the headline: 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 4.25 kA at 690 V. That high interrupt rating at 240 V tells you this breaker is designed for high-fault-current panels — think large transformer secondaries or busway-fed switchboards where available fault current runs north of 100 kA. The 690 V figure (4.25 kA) is lower, but still adequate for most 690 V motor control centers where the transformer impedance typically limits fault current. Rated insulation voltage is 800 V, so it can be used in 690 V systems without derating the insulation path. The auxiliary contact configuration is 1 auxiliary switch + 1 trip alarm switch (HQ type), which gives you one N/O or N/C signal for breaker position and a separate alarm contact that closes only on a trip event — useful for remote annunciation without wiring through the breaker status. ## Thermal performance and panel integration The breaker carries its full 160 A rating from 40 °C up to 50 °C ambient. Above that, it derates linearly: 154 A at 55 °C, 148 A at 60 °C, 142 A at 65 °C, and 136 A at 70 °C. If your panel ambient runs hot — say, a non-ventilated enclosure near a furnace line — you need to account for that 10–15 % reduction at the top end. The maximum power loss is 25.5 W, which is moderate for a 160 A frame; factor it into your enclosure thermal budget. Dimensions: 86 mm deep, 105 mm wide, 181 mm tall. That 105 mm width is standard for a 160 A frame in the SENTRON 3VA platform — it occupies three 35 mm DIN spaces (3 x 35 mm = 105 mm). The front IP40 rating means it's protected against tools and wires >1 mm, but not against moisture; keep it inside a sealed enclosure if washdown is nearby. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. The storage limit governs handling during transport in cold climates — the breaker can sit in an unheated warehouse at -40 °C, but don't energize it until it warms above -25 °C. ## Lifecycle and sourcing reality For procurement: this part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — the high breaking capacity and ETU350 trip unit make it a common specification for 160 A feeder breakers in industrial switchboards, so lead times are generally manageable but vary with global semiconductor availability for the electronic trip unit.","metaTitle":"Siemens 3VA2116-5HN32-0AF0 SENTRON MCCB, 160 A, 3-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2116-5HN32-0AF0 molded case circuit breaker, 160 A rated current, 3-pole, ETU350 electronic trip unit.
