The C60HC6RA30 is a C60H-series RCBO (residual current circuit breaker with overcurrent protection) from Schneider Electric, combining a 1P+N thermal-magnetic miniature circuit breaker with 30 mA earth-leakage protection in a single 35 mm DIN-rail module.
Schneider Electric lists the C60HC6RA30 as obsolete.
The C curve (5–10 × In magnetic trip) suits loads with moderate inrush, such as small motor starters, lighting banks, or control transformers — the breaker holds through brief startup peaks but trips fast on hard shorts. Class A earth-leakage protection (30 mA instantaneous) catches line-to-ground faults on personnel-protection circuits. Terminal capacity: up to 25 mm² rigid upstream, 16 mm² flexible downstream — enough for 6 A feeder wiring. The positive-break indication gives a visible air gap on the toggle when tripped, which helps lockout/tagout verification.
