People Electric · Residual Current MCCB
Product overview
People Electric RDM1L combines overload and short-circuit protection with residual-current operation in a moulded-case breaker. The125AF configuration is documented in the manufacturer Chinese secondary-distribution handbook. Its125L35/25kA ratings and12kV impulse withstand are independently confirmed by the original100A3P product nameplate.

The listing is limited to the125AF non-delay distribution configuration. Select the breaking grade,current,pole/neutral arrangement and required residual-current setting. Confirm the exact residual-current waveform sensitivity and protection coordination. Delayed versions, other frames,neutralC/D arrangements and accessories are not inferred from the older English table.
Typical applications
- Compatible AC400V50Hz distribution circuits requiring coordinated overload,short-circuit and residual-current protection.
