19mm Width RCBO Residual Current Operated Circuit Breaker Type A 30mA Trip Protection Module C & B Curve L19(B Curve,40A)

19mm Width RCBO Residual Current Operated Circuit Breaker Type A 30mA Trip Protection Module C & B Curve L19(B Curve,40A)

• 1. Dual safety protection: Equipped with overload/short circuit protection and leakage protection (30mA high sensitivity), one machine can handle multiple t-ypes of circuit risks.
• 2. Industrial grade durable structure: The shell is made of flame-retardant material and silver alloy contacts, which are resistant to arc impact and have a lifespan of over 10000 times
• 3. Wide voltage adaptive: supports voltage fluctuations of 80V-440V (conventional products only have 230V ± 10%), suitable for unstable power grid areas
• 4. Compact and space saving: Standard DIN rail installation (35mm), width only 36mm (1P+N specification), saving 50% space in the distribution box
• 5. One click self check function: Press the yellow test button (T button) every month to simulate leakage triggering power failure, ensuring that the protection function is always effective
