The Siemens 3VA1196-5ED26-0AA0 is a SENTRON 2-pole molded case circuit breaker (MCCB) rated 16 A with a TM210 thermal-magnetic overcurrent release, designed for line protection in distribution panels. Its headline breaking capacity — 187 kA at 240 V AC and 121 kA at 415 V AC — means it can safely interrupt fault currents up to those levels without upstream damage, making it suitable for high-fault-capacity installations like industrial switchboards or transformer secondaries where SCCR headroom matters.
Ratings and fit
Rated current holds at 16 A from 40 °C through 55 °C ambient, then derates to 15 A at 60–70 °C — so in a warm enclosure you still get full rating up to 55 °C, which covers most panel interiors without a derate factor. The 2-pole construction handles single-phase or line-to-line loads. Insulation voltage is 500 V, operating voltage 415 V AC or 250 V DC. Dimensions are 70 mm deep, 50.8 mm wide, 130 mm tall — a standard 2-pole MCCB footprint that fits existing SENTRON or 3VA panel bases without re-drilling.
What the IP40 means on the front
IP40 on the front means the breaker face is protected against tools and wires over 1 mm — typical for a panel-mounted MCCB where the front is behind a closed door. The body itself is not sealed for washdown, so keep it inside the enclosure, not on the gland plate.
