Lauritz Knudsen Tripper, RCCB, 25A | 2 Pole | 30mA | Finger proof IP20 terminals | 240V

About the Product

The Tripper RCCB 25A DP 240V AC 30mA is a high-quality Residual Current Circuit Breaker (RCCB) designed to provide advanced protection against earth leakage faults. It is specifically engineered to safeguard users from electric shock & prevent electrical hazards caused by insulation failures or leakage currents.

With a 25A current rating & a 30mA sensitivity level, this RCCB is ideal for applications requiring human safety protection. The double pole (DP) configuration ensures simultaneous disconnection of both phase & neutral conductors, delivering complete circuit isolation during fault conditions.

How the RCCB Works

The RCCB continuously monitors the current difference between phase & neutral:

• Detects imbalance between incoming & outgoing current

• Identifies leakage current to earth

• Trips instantly when leakage exceeds 30mA

• Disconnects both phase & neutral conductors

• Prevents electric shock & reduces risk of fire

This ensures maximum safety for users & electrical installations.

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 protect against earth leakage. An MCB is required for overload & short circuit protection.

5. Where is a 25A RCCB used?
Ans: It is used in residential & commercial circuits such as lighting, sockets, & safety-critical installations.

6. Why is RCCB important?
Ans: It protects humans from electric shock & prevents hazards caused by leakage currents.

7. How is this RCCB installed?
Ans: It is installed on a DIN rail inside a distribution board or electrical panel.
