Description
About the Product
The Tripper RCCB 25A FP 415V AC 300mA is a robust Residual Current Circuit Breaker (RCCB) engineered for use in three phase electrical systems. It provides dependable protection against earth leakage faults, making it ideal for applications where fire prevention & upstream system safety are critical.
With a 25A current rating & a 300mA residual current sensitivity, this RCCB is designed primarily for detecting higher leakage currents that may lead to insulation failure or electrical fires. The four pole (FP) configuration ensures simultaneous disconnection of all three phases & the neutral conductor, delivering complete circuit isolation during fault conditions.
How the RCCB Works
This RCCB continuously monitors current balance across all phases & neutral:
• Detects imbalance caused by leakage current to earth
• Identifies abnormal current flow outside the intended circuit path
• Trips automatically when leakage exceeds 300mA
• Disconnects all three phases & neutral simultaneously
• Helps prevent fire hazards & protects electrical systems
This ensures safe & reliable operation in three phase installations.
Technical Specifications
• Rated current: 25A
• 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 designed for long-term durability & efficient performance:
• Four pole design for complete phase & neutral isolation
• Compact modular construction
• DIN rail mountable for easy installation
• High precision tripping mechanism
• High-quality internal components for long service life
Safety & Protection
• Protects against earth leakage faults
• Designed for fire protection applications
• Reduces risk of insulation-related hazards
• Ensures full isolation of all phases & neutral
• Enhances electrical system safety & reliability
Mounting & Durability
• DIN rail mountable for quick installation

FAQs
1. What is an RCCB?
Ans: An RCCB is a protective device that detects earth leakage currents & disconnects the power supply, but 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 personal safety.
3. What does FP mean?
Ans: FP (Four Pole) means the device disconnects all three phases along with the neutral simultaneously.
4. Does this RCCB provide overload protection?
Ans: No, RCCBs only provide earth leakage protection. An MCB is required separately for overload & short circuit protection.
5. Where is a 25A FP 300mA RCCB used?
Ans: It is used in three phase systems such as industrial panels, upstream distribution boards, & fire protection circuits.
6. Why use 300mA instead of 30mA RCCB?
Ans: 300mA RCCBs are designed for fire protection & system-level safety, while 30mA RCCBs are intended to protect against electric shock.
7. How is this RCCB installed?
Ans: It is installed on a DIN rail inside a distribution board or electrical panel for easy integration into electrical systems.
