Integrated control circuit breaker for distribution and control
The Schneider Electric A9C52316 is an Acti9 Reflex iC60N integrated control circuit breaker, combining overcurrent protection with local and remote switching in a single 3-pole unit rated at 16 A with a C-curve trip characteristic.
Control and signalling
The control circuit accepts multiple voltages — 230 V AC, 24 V AC, 48 V AC, 24 V DC, or 48 V DC — giving flexibility for different panel control voltages without an extra transformer. Supports ON/OFF pushbutton, remote pulse, or maintained (toggle) control, so it can be wired for local manual operation or integrated into a PLC-driven remote shutdown scheme. Local signalling includes a red LED for fault, green for device ON, and flashing patterns for overheat, ready, and tripped states — useful for quick visual diagnostics on the panel door.
Durability and environmental ratings
Rated for 50,000 electrical cycles under AC-1 resistive load and 50,000 mechanical cycles — this is the endurance figure for a panel that sees daily switching, not just fault protection. IP20 finger protection (IEC 60529) means it is safe for installation inside a locked or tool-accessible enclosure but not for exposed outdoor or washdown locations. Pollution degree 3 rating allows use in industrial environments with conductive or dry non-conductive pollution — typical for control panels near production floors. Tropicalisation level 2 and 93% relative humidity at 40 °C mean it handles warm, humid conditions without internal condensation issues.
