Tips: 16 amp 4 pole miniature circuit breaker applications

A 16 amp 4-pole miniature circuit breaker (MCB) is typically used in industrial and commercial electrical systems for protecting circuits against overcurrent and short circuits. Its 4 pole configuration is ideal for three-phase systems with a neutral line, protecting all conductors in the circuit (three phases and neutral).

Common applications include:

  • Power Distribution Panels: Protecting circuits that supply machinery or equipment, ensuring the safety of both electrical installations and operators.
  • Motor Protection: Safeguarding three-phase motors that require simultaneous protection of all phases and the neutral.
  • UPS Systems: Protecting uninterruptible power supplies, ensuring safe shutdown and preventing damage to sensitive electronics during faults.
  • Renewable Energy Systems: In solar or wind power installations, providing overcurrent protection to the inverter and associated wiring.

The 16 amp rating indicates it’s suitable for medium-sized systems, offering reliable protection without unnecessary tripping. Always ensure the breaker’s ratings match the circuit load to avoid damage.

This MCB is perfect for my applications.
This 16 amp 4 pole miniature circuit breaker can protect my solar controller from damage by disconnecting solar power panel until battery connection is made. Perfect for my applications. Very pleased with this order and I would buy more if I need.

Worked perfectly for my application.
I bought this miniature circuit breaker last week. I used it as a switch on the DC input side of my PV charge controller. The DIN rail is wide enough for installing a protector next to it. I am happy with this purchase. I will buy again from ATO.com.
