2p 100a Tpn Mccb with Rcd Protection

2p 100a tpn mccb with rcd protection is a 100A 2 pole or four pole moulded case circuit breaker with residual current device. It could detect the imbalance of working current to cut off the power supply within milliseconds when the surface of the electrical equipment is electrified.

The 2p 100a mccb with rcd protection is widely applied on single phase electricity, such as residential and commercial circuit, lighting circuit, and small capacity electricity. Aditionally, the 2p means one pole for live wire and another for neutral wire.

The TPN mccb with rcd protection serves on three phase four wire system. Obviously, it is designed for industrial system, photovoltaic inverter output side, and other heavy loading. Compare with 3P mccb, the The TPN mccb with rcd protection could shut down the neutral line with 3 phase live line to supply a safer working environment.

2p 100a tpn mccb with rcd protection FAQ:

Q1: What does “100A MCCB with RCD protection” mean?

It refers to a moulded case circuit breaker rated at 100A that combines standard overcurrent and short circuit protection with a residual current device. In simple terms, it protects to against short circuit, overload, and earth leakage faults.

Q2: What is the difference between 2P and TPN in MCCB with RCD protection?

A 2P MCCB is designed for single phase systems, where it switches phase and neutral.

TPN is used in three phase four wire systems, where all three phases and the neutral can be isolated. The choice depends on the type of power distribution system.

Q3: What is the benefit to have RCD protection in an 100A MCCB?

The RCD function detects leakage current to earth and disconnects the circuit within milliseconds. It provides additional safety against electric shock and reduces the risk of electrical fires caused by insulation failure or ground faults.
