Max Hauri Build FI/LS 3P+N residual-current circuit-breaker, Type A detection, Type C tripping, 16 A, 30 mA, 6 kA, 4-pole for three-phase distribution boards.
The Max Hauri Build FI/LS 3P+N C 16A 30mA 6kA is a residual-current circuit-breaker with Type A residual-current detection and Type C tripping characteristic. It provides dedicated protection against electric shock and fire hazards in residential and commercial electrical installations.
Type A residual-current device detects both sinusoidal and pulsating DC residual currents, offering broader protection than Type AC devices
Type C tripping characteristic handles a wide range of fault current waveforms, including smooth DC components up to 6 mA
30 mA tripping threshold ensures rapid disconnection to prevent dangerous electric shock incidents
16 A rated current with 4 poles (3P+N) suits standard three-phase plus neutral distribution boards
6 kA short-circuit breaking capacity provides robust protection in modern low-voltage networks
Das zeichnet Max Hauri Build FI/LS 3P+N C 16A 30mA 6kA Type A aus
The Type A residual-current detection is the key differentiator: unlike Type AC devices, it reliably trips on pulsating DC fault currents that are increasingly common in modern electronic equipment and inverter-driven systems. The Type C characteristic further extends the range of detectable fault conditions, making this device suitable for circuits feeding computers, LED drivers, and similar electronic loads.
Ideal für...
Designed for installation in three-phase distribution boards in residential buildings, commercial premises, and light-industrial facilities where enhanced residual-current protection is required. It is particularly suited for circuits powering electronic equipment, HVAC controls, and automation systems that may introduce DC fault components.
Anwendung von Max Hauri Build FI/LS 3P+N C 16A 30mA 6kA Type A
Install in a distribution board on a 3-phase + neutral circuit with up to 16 A load current
Connect the three phase conductors and the neutral through the device terminals
Ensure the upstream short-circuit protection is rated for the 6 kA breaking capacity
Verify the 30 mA tripping threshold meets the installation requirements per local electrical regulations
Max Hauri Build is a Swiss electrical equipment brand offering residual-current devices and circuit-breakers for residential and commercial distribution systems. The product line focuses on reliable fault-current protection with modern Type A and Type C characteristics.
A Type A RCD detects both sinusoidal AC and pulsating DC residual currents. Unlike Type AC devices, it can trip on DC fault components that are common in modern electronic equipment such as inverters, LED drivers, and computers, providing broader and more reliable protection.
Type C tripping characteristic means the device can handle a wide range of fault current waveforms, including those with smooth DC components up to 6 mA. This makes it suitable for circuits feeding electronic loads that produce DC fault components.
The 6 kA short-circuit breaking capacity indicates the maximum fault current the device can safely interrupt. This rating ensures the circuit-breaker can protect the installation and personnel in modern low-voltage networks with typical short-circuit levels.
The delivery includes one Max Hauri Build FI/LS 3P+N C 16A 30mA 6kA Type A residual-current circuit-breaker. Mounting accessories and terminal connections are not included and must be sourced separately per the installation requirements.
A 30 mA tripping threshold is the standard sensitivity for personal protection. It ensures the device disconnects the circuit within milliseconds when a ground fault current exceeds 30 mA, significantly reducing the risk of dangerous electric shock to persons in the installation.
