Eaton PFIM-100/4/003-A 100A 4P 30mA

FAQ (customer)

• Q: Is this device suitable for a typical home socket circuit?
  A: Yes, the 16 A rating with C characteristic and 30 mA RCD sensitivity is suitable for standard single-phase socket and mixed circuits in residential installations, provided the wiring is correctly sized.
• Q: Can I use this RCBO in a 3-phase installation?
  A: This specific model is designed for single-phase 230 V AC circuits; for 3-phase installations you need corresponding multi-pole devices.
• Q: Do I still need a separate RCD if I install this product?
  A: No, this RCBO combines overcurrent and residual current protection in one device, eliminating the need for a separate RCD for that particular circuit.
• Q: Is it compatible with standard DIN rail consumer units?
  A: Yes, it is designed for mounting on 35 mm DIN rail and fits regular modular consumer units used in Europe.
• Q: What type of loads can I connect to this breaker?
  A: It can supply typical household loads such as sockets, lighting, small appliances, and electronic equipment within the 16 A limit and appropriate wiring.
• Q: Does it protect against electric shock?
  A: Yes, the 30 mA residual current protection offers enhanced protection against indirect contact and reduces the risk of electric shock.

FAQ (expert)

• Q: What type of residual current does the A-type module detect?
  A: It detects sinusoidal AC residual currents and pulsating DC residual currents, which is suitable for many modern loads with single-phase power electronics.
• Q: What is the rated short-circuit capacity of this RCBO?
  A: The device has a 6 kA breaking capacity, appropriate for typical domestic and small commercial installations with coordinated upstream protection.
• Q: Can this RCBO be used as the main incomer protection?
  A: It is primarily intended for final circuits; main incomer protection usually requires appropriately rated main breakers and often selective RCDs depending on system design.
• Q: Is there any selectivity or coordination information for upstream MCBs or fuses?
  A: Coordination should follow Eaton’s coordination tables and local standards, ensuring the upstream device has an equal or higher breaking capacity and suitable time-current characteristics.
• Q: What ambient temperature range should be considered for rating adjustments?
  A: Standard rating assumes typical indoor ambient conditions; for elevated temperatures, apply general derating guidelines provided in Eaton technical documentation for modular protection devices.
• Q: Are there accessories like phase busbars compatible with this series?
  A: Yes, Eaton modular devices in the xPole Home system are generally compatible with standard phase busbars designed for that system; selection depends on pole configuration and number of devices.

Reviews

• Reliable RCBO that fits easily into standard DIN rail consumer units; installation was straightforward and labeling is clear.
• After replacing separate MCB and RCD with this single device, the board is tidier and there is more space for additional circuits.
• Provides stable operation with no nuisance tripping, even with several electronic appliances on the same circuit.
• Good quality housing and solid terminal connections give a professional impression during installation.
• The combination of 16 A, C curve, and 30 mA sensitivity is ideal for typical home socket circuits in my projects.
• Works well in renovation projects where saving space in older consumer units is critical.
• Trustworthy brand and clear technical data made it easy to include in electrical design documentation.
• After several months of use there have been no issues; testing with an RCD tester confirms proper trip times.
• Neat design that aligns well with other Eaton xPole devices, giving a uniform look in the distribution board.
• Electricians appreciate the integrated protection concept, reducing wiring complexity and potential points of failure.
