SCHNEIDER A9Z51225 Residual Current Circuit Breaker RCCB Type AC 2P 25A 30mA

RCD Circuit Breaker SCHNEIDER A9Z51225 Residual Current Device RCCB Type AC 2P 25A 30mA

The A9Z51225 is a DIN rail-mounted residual current circuit breaker providing protection against direct and indirect contact hazards for 1-phase 2P AC systems at 230 VAC 50 Hz. The key feature that sets this product apart is its Type B-EV classification, representing the highest level of residual current protection capable of detecting all types of leakage currents.

Specifications
- Type B-EV Protection: The most prominent feature is the ability to detect leakage currents with smooth DC components, essential for EV charger safety
- Voltage Independent: The tripping mechanism operates independently of voltage, allowing it to trip even under abnormal voltage conditions (except when voltage falls below specified limits)
- VisiSafe: A green strip on the toggle indicates that contacts are fully open and safe for maintenance
- VisiTrip: Mechanical trip indicator allows instant identification of faulty circuits, reducing troubleshooting time. Installed together with MCB: a device that must
- Install together with a Miniature Circuit Breaker (MCB) for overcurrent and short-circuit protection (acts only as earth leakage/electric shock protection)

Applications & Usage
- EV Charger: Primarily and specifically designed for this application to comply with strict safety requirements for residential and commercial electric vehicle charging.
- Systems with Inverters/Converters: Used in circuits supplying power to equipment with power conversion, such as high-grade UPS systems, solar inverters (in certain installations), or other power electronic devices that may generate DC leakage current.
