100amp 4 pole rcd breaker

A 100A 4-pole RCD (Residual Current Device) breaker is a type of electrical breaker that is designed to provide both overcurrent protection and earth fault protection in a 4-pole circuit.

Here's a breakdown of the specifications:

• 100A: The maximum current rating of the breaker, which means it can handle up to 100 amperes of current flow.
• 4-pole: The breaker has four poles, which means it can control four separate circuits or phases. This is typically used in 3-phase or 4-wire systems.
• RCD: The breaker is a Residual Current Device, which means it is designed to detect and interrupt earth faults (i.e., faults between the live conductors and earth) in addition to overcurrents.

Some common applications for a 100A 4-pole RCD breaker include:

• Industrial power distribution systems
• Commercial building electrical systems
• Large residential electrical systems (e.g., in homes with multiple phases or high-power appliances)
• Agricultural or rural electrical systems

When selecting a 100A 4-pole RCD breaker, you should consider the following factors:

• Compatibility: Ensure the breaker is compatible with your electrical system's voltage, frequency, and wiring configuration.
• Rating: Verify that the breaker's current rating (100A) is sufficient for your circuit's maximum expected current.
• Trip characteristics: Check the breaker's trip characteristics, such as its trip time and sensitivity, to ensure it meets your system's requirements.
• Certifications: Look for certifications from reputable testing organizations, such as UL (Underwriters Laboratories) or ETL (Intertek), to ensure the breaker meets safety and performance standards.

It's always a good idea to consult with a licensed electrician or electrical engineer if you're unsure about selecting the right breaker for your specific application.
