Lauritz Knudsen Tripper, RCCB, 40A | 4 Pole | 30mA | Finger proof IP20 terminals | 415V AC | ISI Certified

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.

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.
