The Schneider Electric A9C61316 is a Reflex iC60N Ti24 integrated control circuit breaker from the Acti9 range — a 3-pole, 16 A device with a B-curve thermal-magnetic trip unit. It combines overcurrent protection with remote control capability in a single DIN-rail module, so you can both switch and protect a distribution or control circuit from one panel position.
The control circuit accepts several voltage options: 230 V AC, 24 V AC, 48 V AC, 24 V DC, or 48 V DC. That flexibility saves stocking multiple coil-voltage variants — one part number covers the common panel voltages. Control can be maintained (continuous ON/OFF), impulse (pulse-triggered), or maintained very low voltage, which maps to different PLC output types without extra interface relays. The local signalling LED shows device ON (green), tripped (flashing), overheat (flashing), and fault (red) — you get the status at a glance without a multimeter or a bus read. For lockout/tagout, the padlock provision in the OFF position lets you secure the breaker during line-side work.
The 3-pole footprint is what you expect for a 3P breaker; no surprises on the panel layout. The tropicalisation class 2 treatment handles humidity up to 93 % at 40 °C without derating, which matters for un-air-conditioned plants in hot climates.
