People Electric · DC Moulded Case Circuit Breaker
Product overview
People Electric RDM8DC moulded-case circuit breakers protect DC distribution circuits with thermal overload and instantaneous electromagnetic releases. The manufacturer specifies five frame sizes, two- or three-pole construction and different short-circuit ratings by DC voltage and pole configuration.

Frame, pole count and operating voltage are combined to avoid unsupported configurations. Rated current is restricted to that frame. Specify polarity, earthing arrangement and the exact manufacturer connection diagram; pole count alone does not establish a permitted DC wiring arrangement. Confirm auxiliary accessories, operating mechanism and mounting dimensions before ordering.
Typical applications
- DC distribution and photovoltaic-associated DC circuits within the stated breaker voltage, fault-current and wiring ratings.
