People Electric · Moulded Case Circuit Breaker
Product overview
People Electric RDM1 moulded-case circuit breakers are used for distribution switching and fault protection with the specified release and accessories. The series includes different frames, breaking levels and pole/voltage versions. Select the exact documented combination before choosing current; a common frame number does not establish a common breaking rating or pole arrangement.

Only combinations explicitly listed in the main technical tables are offered. Parenthesized special 6A (63A frame) and 10A (125A frame) entries require separate confirmation and are not offered here. AC690V is not available as a universal option. A/B neutral choices apply only to 4P. The source drawing caption RDM1-125M is not used as proof of 1250A-frame dimensions; obtain the exact mounting drawing for that frame. Confirm release, accessory supplies and exact order code before purchase.
Typical applications
- AC industrial and commercial distribution circuits requiring an exact MCCB frame, pole arrangement and fault-level rating.
- Distribution or motor-protection applications using the correctly specified release and coordinated accessories.
