Description
About the Product
The Tripper RCCB 40A FP 415V AC 30mA is a high-performance Residual Current Circuit Breaker (RCCB) designed for use in three phase electrical systems. It provides effective protection against earth leakage faults, helping prevent electric shock & ensuring safe operation of electrical installations.
With a 40A current rating & a highly sensitive 30mA residual current threshold, this RCCB is ideal for applications that require protection for human safety. The four pole (FP) configuration ensures simultaneous disconnection of all three phases along with the neutral conductor, providing complete isolation of the circuit during fault conditions.
How the RCCB Works
The RCCB continuously monitors current flow across all phases & neutral:
• Detects imbalance between incoming & outgoing current
• Identifies leakage current flowing to earth
• Trips immediately when leakage exceeds 30mA
• Disconnects all three phases & neutral simultaneously
• Protects users from electric shock & electrical hazards
This ensures maximum safety in three phase electrical systems.
Technical Specifications
• Rated current: 40A
• Poles: Four pole (FP – 3 phase + neutral)
• Rated voltage: 415V AC
• Residual current sensitivity: 30mA
• Function: Earth leakage protection
• Application: Three phase circuits requiring human safety protection
Construction & Design
The RCCB is engineered for durability & precision:
• Four pole design for complete three phase & neutral isolation
• Compact modular construction
• DIN rail mountable for easy installation
• High-precision tripping mechanism
• Robust internal components for long service life
Safety & Protection
• Protects against earth leakage faults
• Provides protection against electric shock
• Ensures complete disconnection of all phases & neutral
• Reduces risk of electrical fire hazards
• Improves safety & compliance in three phase systems
Mounting & Durability
• DIN rail mountable for quick & easy installation
• Suitable for distribution boards & control panels
• Compact design for efficient panel space usage
• Designed for long mechanical & electrical life
• Reliable under continuous operation
Application Areas
• Industrial & commercial electrical systems
• Three phase distribution boards
• Motor & equipment protection circuits
• Safety-critical installations
• Commercial infrastructure
Key Features
• 40A rated RCCB for three phase applications
• Four pole (FP) configuration for full isolation
• 30mA sensitivity for human safety protection
• Accurate earth leakage detection
• Compact DIN rail mountable design
• Durable & reliable construction
Applications
• Three phase electrical systems
• Industrial & commercial installations
• Motor & equipment safety circuits
• Electrical safety panels
• Distribution boards
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 FP mean?
Ans: FP (Four Pole) means it disconnects all three phases along with the neutral 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 FP RCCB used?
Ans: It is used in three phase systems such as industrial panels, motor circuits, & commercial installations requiring safety protection.
6. Why use a four pole RCCB?
Ans: A four pole RCCB ensures complete isolation of all phases & neutral, improving safety during faults & maintenance.
7. How is this RCCB installed?
Ans: It is installed on a DIN rail inside a distribution board or control panel.
