Description
About the Product
The AU RCBO 25A FP 415V AC 10kA 30mA C Curve is a four pole protection device that integrates both MCB & RCCB functions into a single compact unit. It is designed for three phase electrical systems requiring comprehensive & reliable circuit protection.
With a 25A current rating, this RCBO is suitable for medium to higher load three phase circuits such as machinery, equipment loads, & commercial distribution systems. The 30mA leakage sensitivity provides effective protection against electric shock, making it ideal for safety-critical applications.
How the RCBO Works
This four pole RCBO operates as a complete protection system:
• Detects overload & short circuit conditions similar to an MCB
• Detects earth leakage currents like an RCCB
• Trips automatically when abnormal conditions occur
• Disconnects all three phases & neutral simultaneously
This ensures total circuit isolation & enhanced safety in three phase installations.
