Description
About the Product
The AU RCBO 16A FP 415V AC 10kA 30mA C Curve is a four pole residual current breaker with overload protection that integrates both MCB & RCCB functionalities in a single unit. It is specifically designed for three phase systems requiring comprehensive circuit protection.
With a 16A current rating, this RCBO is suitable for medium load three phase circuits. The 30mA leakage sensitivity ensures effective protection against electric shock, making it ideal for safety-focused commercial & industrial installations.
How the RCBO Works
This four pole RCBO operates as a combined protection system:
• Detects overload & short circuit conditions similar to an MCB
• Detects earth leakage currents like an RCCB
• Trips automatically when fault conditions are detected
• Disconnects all three phases & neutral simultaneously
This ensures complete isolation of the circuit & enhanced protection in three phase systems.
Electrical Configuration
• Rated current: 16A
• Poles: Four pole (FP – 3 phase + neutral)
• Rated voltage: 415V AC
• Breaking capacity: 10kA
• Sensitivity: 30mA
• Trip curve: C Curve
• Application: Overload, short circuit, & earth leakage protection
Construction & Design
The RCBO is designed for reliable three phase operation:
• Integrated MCB & RCCB functionality in one device
• Modular design suitable for DIN rail mounting
• Compact construction for efficient use of panel space
• High mechanical & electrical endurance
• Designed for accurate & consistent tripping performance
Safety & Protection
• Protects against overload & short circuit faults
• 30mA sensitivity provides protection against electric shock
• Detects & isolates earth leakage currents
• Four pole disconnection ensures complete system isolation
• Reduces risk of electrical hazards, fire, & equipment damage
Mounting & Durability
