Line protection MCCB, 16 A frame, TM210 release
It carries 16 A continuously at 40 °C with no derating needed up to 55 °C — only at 60 °C does it step to 15 A, so it holds full rating across most normal panel ambient conditions. Rated insulation voltage is 800 V, and breaking capacity runs 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V — numbers that matter for fault-current coordination studies on the secondary side of a distribution transformer. Three-pole, line-side and load-side lugs accept standard panel wiring. No trip indicator, so fault diagnosis relies on the breaker handle position or a downstream meter.
Width 76.2 mm (3 in), depth 70 mm (2.76 in), height 130 mm (5.12 in). That 3-inch width matches the standard 3-pole MCCB footprint in most North American and European panelboards — no adapter plate needed for a typical cutout. Verify busbar spacing against your existing distribution block before committing the BOM line.
Power loss and thermal budget
Maximum power loss is 10.6 W at rated current. That figure feeds into the panel heat budget — for a multi-breaker enclosure, sum the losses against the enclosure's dissipation curve to avoid nuisance tripping from ambient rise.
