The Clipsal MAX9 1P+N 20A RCBO 30mA Type A (MAX9R3120) is an essential component for residual current protection and overload protection in single-phase electrical circuits. With a 30mA sensitivity rating, 20A current capacity, and Type A protection, it offers comprehensive safety for residential, commercial, and light industrial installations. Its dual protection capability ensures the safety of both the electrical system and the users while preventing damage to sensitive equipment from earth leakage and overcurrent faults.
Dual Protection: Offers both overload protection (via MCB) and earth leakage protection (via RCD) in a single device, saving space and simplifying electrical system design.
Enhanced Safety: The 30mA sensitivity ensures personal protection by cutting off the circuit if an earth leakage current above the threshold is detected.
Type A Protection: Provides enhanced protection for modern circuits that may include electronic devices and DC components that can cause pulsating DC leakage.
Compact and Space-Saving: The DIN rail mountable design ensures a compact form factor, helping save space in switchboards and electrical distribution boar
FEATURES:
The MAX9R3120 provides two-in-one protection by combining an overcurrent protection (MCB) and residual current protection (RCD) in a single device. This makes it convenient and space-efficient for protecting circuits against overload, short circuit, and earth leakage faults.
The Type A RCD protection is designed to detect AC and pulsating DC residual currents, providing protection against faults that are commonly found in circuits with electronic devices like computers, washing machines, and other appliances with rectifiers or DC components.
The 30mA sensitivity rating of the RCD is designed to protect against electric shock by disconnecting the circuit if it detects an earth leakage current greater than 30mA. This is the recommended value for personal protection in residential and commercial environments.
The MAX9R3120 is rated for 20A, making it suitable for use in circuits that require a 20A current capacity. It ensures safe operation in circuits that may have equipment or devices consuming up to 20A of current.
The 1P+N configuration means that the MAX9R3120 is designed for use in single-phase circuits with neutral, making it suitable for typical residential and light commercial electrical installations.
