Key Features

• 4-Pole Protection: Covers all three phases and neutral, ideal for three-phase installations.

• High Current Rating: Rated at 63A, suitable for medium to high-load circuits.

• 300mA Sensitivity: Designed for indirect contact protection and fire prevention, rather than personal protection (which usually uses 30mA).

• Type AC Leakage Detection: Handles sinusoidal AC leakage, appropriate for most general-purpose electrical systems.

• Compatible with iC60 Breakers: Designed to attach directly to Schneider iC60 series circuit breakers.

• Test Functionality: Integrated test button for routine maintenance and functionality checks.

• Quick Mounting: Tool-less DIN rail mounting simplifies installation and upgrades.

Applications

The Schneider A9V44463 is suited for a wide range of use cases, especially in scenarios where earth fault protection is required but high leakage levels are permissible.

Industrial Applications

• Suitable for factories, production lines, and heavy machinery setups where operational leakage may be higher than residential limits.

Fire Protection

• The 300mA sensitivity allows detection of leakage currents that could cause thermal stress and lead to electrical fires, even if not harmful to humans.

Three-Phase Systems

• Perfect for commercial buildings, large HVAC units, pumping stations, and three-phase distribution boards requiring residual current protection on all lines.

Panel Upgrades

• Easy to add to existing iC60 breakers, offering a straightforward way to enhance safety without replacing the full distribution system
