Description
About the Product
The AU RCCB 40A DP 240V ADI 100mA is a high-quality Residual Current Circuit Breaker designed to detect earth leakage currents & provide effective protection for electrical systems. It focuses on safeguarding equipment & preventing fire hazards caused by leakage currents rather than direct personal protection.
Equipped with ADI (Advanced Detection Intelligence) technology, this RCCB delivers precise & stable leakage detection. With a 40A rating, it is suitable for medium to high load applications in residential & commercial environments.
How the RCCB Works
This RCCB provides dedicated earth leakage protection through continuous monitoring:
• Monitors the current balance between live & neutral
• Detects leakage due to insulation faults or wiring issues
• Trips instantly when leakage exceeds 100mA threshold
• Disconnects both live & neutral through double pole operation
This ensures quick isolation of faulty circuits & improved system safety.
Electrical Configuration
• Rated current: 40A
• Poles: Double pole (DP)
• Rated voltage: 240V AC
• Technology: ADI (Advanced Detection / Intelligent sensing)
• Sensitivity: 100mA
• Function: Earth leakage protection only
• Application: Equipment protection & fire safety
Construction & Design
The RCCB is engineered for durability & reliable operation:
• Dedicated RCCB functionality for accurate leakage detection
• Advanced ADI sensing for improved performance
• Modular design compatible with DIN rail mounting
• Compact structure for efficient panel space usage
• High mechanical & electrical endurance
• Designed for stable & consistent tripping
Safety & Protection
• Detects earth leakage currents effectively
• 100mA sensitivity suitable for equipment protection & fire prevention
• Double pole isolation ensures complete circuit disconnection
• Reduces risk of electrical fires caused by leakage faults
• Enhances overall electrical system safety
Mounting & Durability
• DIN rail mounting for quick & easy installation• Suitable for residential & commercial distribution boards
• Compact modular construction
• Designed for repeated operation & long-term use
• Built for reliable performance in moderate to high load conditions
Application Domains
• Residential distribution boards

• Appliance & equipment circuits
• Fire protection systems
• Electrical safety applications
Key Features
• 40A rated RCCB for medium to high load circuits
• Double pole design for complete circuit isolation
• 100mA sensitivity for equipment protection & fire safety
• ADI technology for advanced leakage detection
• Dedicated earth leakage protection device
• DIN rail compatible for easy installation
• Compact & durable construction
Applications
• Residential electrical systems
• Commercial installations
• Appliance circuits
• Distribution boards
• Fire safety & equipment protection systems
FAQs
1. What is the function of this RCCB?
Ans: It detects earth leakage currents & disconnects the circuit to prevent equipment damage & fire hazards.
2. What does 100mA sensitivity indicate?
Ans: It indicates the leakage current level at which the device trips & is mainly used for fire protection rather than personal safety.
3. Does this RCCB provide overload protection?
Ans: No, it must be used with an MCB or fuse for overload & short circuit protection.
4. Why is double pole protection important?
Ans: It disconnects both live & neutral, ensuring complete circuit isolation during faults.
5. Where is a 40A RCCB used?
Ans: It is used in medium to high load circuits such as residential & commercial distribution systems.
6. What is ADI technology?
Ans: ADI improves leakage detection accuracy & ensures reliable tripping performance.
7. Where should this RCCB be installed?
Ans: It should be installed in distribution boards to protect circuits from earth leakage faults.

Warranty
- All products listed in the price list are covered by a warranty against manufacturing defects for a period of 18* months from the date of purchase.
- For Lauritz Knudsen MCBs & Isolators mounted inside Lauritz Knudsen Distribution Boards, an extended warranty of 5 years is provided.
- In the event of a defect due to faulty workmanship or other associated reasons, the manufacturer will, at its discretion, remedy the defect or replace the faulty parts or the entire product as soon as possible, free of cost.
- This warranty is subject to proper usage and efficient maintenance and does not cover defects arising from fire, accidents, inefficient maintenance, faulty operation, or deliberate or accidental damage.
- The warranty does not cover damage to power electronic components such as thyristors & IGBTs, which primarily fail due to over-temperature or over-voltage. Users must take adequate precautions to eliminate such conditions.
- The manufacturer shall not be responsible or liable for any special, incidental, social, or consequential losses (including loss of profits), punitive damages, injury, or damages of any kind solely attributable to defect or failure of its products.
- The manufacturer shall not be liable in any manner for issues related to or failure in the performance of any other equipment to which the product is connected.
