Description
About the Product
The Tripper RCCB 63A FP 415V AC 300mA is a heavy-duty Residual Current Circuit Breaker (RCCB) engineered for use in demanding three phase electrical systems. It delivers reliable protection against earth leakage faults & is ideally suited for fire protection & upstream system safety applications.
With a 63A current rating & a 300mA residual current sensitivity, this RCCB is designed to detect higher leakage currents that may result from insulation failure, thereby helping prevent electrical fires. The four pole (FP) configuration ensures simultaneous disconnection of all three phases along with the neutral conductor, ensuring complete circuit isolation during fault conditions.
How the RCCB Works
This RCCB continuously monitors current balance across all phases & neutral:
• Detects imbalance between incoming & outgoing current
• Identifies leakage current flowing to earth
• Trips automatically when leakage exceeds 300mA threshold
• Disconnects all three phases & neutral simultaneously
• Helps prevent fire hazards caused by sustained leakage currents
This ensures safe, stable, & reliable operation of electrical systems.
Technical Specifications
• Rated current: 63A
• Poles: Four pole (FP – 3 phase + neutral)
• Rated voltage: 415V AC
• Residual current sensitivity: 300mA
• Function: Earth leakage protection
• Application: Fire protection & upstream safety circuits
Construction & Design
The RCCB is built for durability & long-term performance:
• Four pole design for complete phase & neutral isolation
• Compact modular construction
• DIN rail mountable for easy installation
• High precision tripping mechanism
• Robust internal components ensuring reliability
Safety & Protection
• Protects against earth leakage faults
• Designed specifically for fire protection applications
• Reduces risk of insulation-related electrical hazards
• Ensures full disconnection of all phases & neutral
• Enhances system safety & reliability
Mounting & Durability
• DIN rail mountable for quick installation
• Suitable for distribution boards & control panels
• Compact design for efficient panel space utilization
• Designed for long mechanical & electrical life
• Reliable under continuous high-load operation
Application Areas
• Industrial & commercial electrical systems
• Main distribution & upstream protection circuits
• High load machinery & equipment
• Fire protection installations
• Three phase electrical distribution boards
Key Features
• 63A rated RCCB for high load three phase applications
• Four pole (FP) configuration with full isolation
• 300mA earth leakage sensitivity for fire protection
• Accurate leakage detection & rapid tripping
• Compact DIN rail mountable design
• Durable & heavy-duty construction
Applications
• Upstream distribution protection
• Fire risk mitigation systems
• Industrial & commercial installations
• Heavy equipment circuits
• Electrical distribution panels
FAQs
1. What is an RCCB?
Ans: An RCCB is a device that detects earth leakage currents & disconnects power supply, but it does not provide overload or short circuit protection.
2. What does 300mA sensitivity mean?
Ans: It means the RCCB trips when leakage current exceeds 300mA, mainly used for fire protection rather than direct protection against electric shock.
3. What does FP mean?
Ans: FP (Four Pole) means the device disconnects all three phases along with the neutral conductor simultaneously.
4. Does this RCCB protect against overload?
Ans: No, RCCBs only provide earth leakage protection. An MCB is required separately for overload & short circuit protection.
5. Where is a 63A FP 300mA RCCB used?
Ans: It is used in high load three phase systems such as industrial machinery, HVAC systems, & upstream distribution boards where fire protection is essential.
6. Why use 300mA instead of 30mA RCCB?
Ans: 300mA RCCBs are designed for fire protection & upstream safety, while 30mA RCCBs are used for protection against electric shock.
7. How is this RCCB installed?
Ans: It is installed on a DIN rail inside a distribution board or electrical panel.
