Description
About the Product
The Tripper RCCB 40A DP 240V AC 30mA is a high-performance Residual Current Circuit Breaker (RCCB) designed to provide advanced protection against earth leakage faults. It safeguards users from electric shock & helps prevent electrical hazards caused by insulation failure or leakage currents.
With a 40A current rating & a 30mA sensitivity, this RCCB is ideal for circuits that require human safety protection. The double pole (DP) configuration ensures simultaneous disconnection of both phase & neutral conductors, delivering complete isolation during fault conditions.
How the RCCB Works
The RCCB continuously monitors the difference between incoming & outgoing current:
• Detects imbalance between phase & neutral
• Identifies leakage current flowing to earth
• Trips instantly when leakage exceeds 30mA
• Disconnects both phase & neutral simultaneously
• Prevents electric shock & reduces fire risks
This ensures high-level safety for both users & installations.
Technical Specifications
• Rated current: 40A
• Poles: Double pole (DP)
• Rated voltage: 240V AC
• Residual current sensitivity: 30mA
• Function: Earth leakage protection
• Application: Circuits requiring human safety protection
Construction & Design
The RCCB is designed for durability & precision:
• Double pole configuration for full isolation
• Compact modular design
• DIN rail mountable for easy installation
• High-precision tripping mechanism
• Robust internal construction for long service life
Safety & Protection
• Protects against earth leakage faults
• Provides electric shock protection
• Reduces the risk of electrical fires
• Ensures full disconnection of phase & neutral
• Improves safety & compliance in electrical systems
Mounting & Durability
• DIN rail mountable for quick installation
• Suitable for distribution boards & panels
• Compact footprint for efficient panel usage
• Long mechanical & electrical life
• Reliable under continuous operation
Application Areas
• Residential electrical systems
• Commercial installations
• Socket & lighting circuits
• Bathroom & wet area safety circuits
• Distribution boards
Key Features
• 40A rated RCCB for higher load circuits
• Double pole (DP) configuration for full isolation
• 30mA sensitivity for human safety protection
• Accurate earth leakage detection
• Compact DIN rail mountable design
• Durable & high-reliability construction
Applications
• Residential safety protection circuits
• Socket & lighting systems
• Bathroom & kitchen wiring
• Electric shock protection

FAQs
1. What is an RCCB?
Ans: An RCCB is a device that protects against earth leakage currents & electric shock but does not provide overload or short circuit protection.
2. What does 30mA sensitivity mean?
Ans: It means the RCCB trips when leakage current exceeds 30mA, providing protection against electric shock.
3. What does DP mean?
Ans: DP (Double Pole) means both phase & neutral are disconnected simultaneously.
4. Does this RCCB protect against overload?
Ans: No, RCCBs only provide earth leakage protection. An MCB is required for overload & short circuit protection.
5. Where is a 40A RCCB used?
Ans: It is used in residential & commercial circuits such as lighting, sockets, & safety-critical areas.
6. Why is RCCB important?
Ans: It protects users from electric shock & prevents hazards caused by electrical leakage.
7. How is this RCCB installed?
Ans: It is installed on a DIN rail inside a distribution board or electrical panel.

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.
