Integrator note: 80 A MCCB with TM210 release
The Siemens 3VA1116-4FD42-0AA0 is a SENTRON molded case circuit breaker (MCCB) rated at 80 A continuous, configured as a 4-pole unit with a TM210 thermal-magnetic overcurrent release. The TM210 designation indicates a fixed thermal pickup and a magnetic trip threshold set at 10× the rated current (800 A magnetic instantaneous), which governs short-circuit protection for line-feeder and distribution applications. Breaking capacity is specified across multiple voltage levels: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. These figures define the maximum fault current the breaker can safely interrupt at each voltage — essential for verifying SCCR coordination with upstream gear in a panel schedule. Thermal derating is published across a 40 °C to 70 °C ambient band: the breaker carries 160 A continuously at 40 °C, 45 °C, and 50 °C, then derates to 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. For a panel enclosure running at 55 °C ambient, the effective continuous rating drops to 158 A — a factor to confirm against the connected load before committing the BOM line.
Dimensions and panel fit
Physical footprint: 130 mm height, 101.6 mm width, 70 mm depth. The 4-pole width (101.6 mm / 4 in) is standard for a 4-pole MCCB in this frame size; verify the DIN-rail or mounting-plate spacing in the existing panel if replacing a different make. IP40 on the front face means the breaker is protected against solid objects >1 mm but not against water ingress — suitable for indoor panel mounting, not washdown zones.
Lifecycle and compliance posture
Rated insulation voltage is 800 V, and maximum power loss is 38 W. The breaker is designed for line protection (not motor or generator protection), with no undervoltage release, no trip indicator, and no communication function. These omissions are by design for a basic thermal-magnetic feeder breaker — the absence of a trip indicator means fault-event diagnostics rely on external metering or a separate indication auxiliary.
