The C60HC20R100 is a C60H-series RCBO (residual current circuit breaker with overcurrent protection) from Schneider Electric — 1 pole + N, rated 20 A at 30 °C, C-curve magnetic trip (5 to 10 × In), with 100 mA earth-leakage sensitivity (Class AC, instantaneous). It breaks up to 10 kA Icu at 50–250 V AC, 50/60 Hz, per IEC 1009-2-2.
The C curve (5–10 × In) means the magnetic trip fires between 100 A and 200 A — designed for mixed resistive-inductive loads like small motor circuits, lighting banks, and control transformers where inrush is moderate but not as high as a D-curve would handle. The 100 mA earth-leakage threshold is for equipment protection, not personnel shock protection (that needs 30 mA or lower); it catches insulation faults before they escalate to a phase-to-ground short. Thermal-magnetic trip technology combines a bimetal strip for overload protection (time-delayed, inverse-time) and a solenoid for short-circuit protection (instantaneous above the magnetic threshold). The 20 A rating at 30 °C ambient means the thermal element tracks load current; derate for higher ambient temperatures per the manufacturer's curve.
Deployment context
The 1P+N format (switched phase, solid neutral) is typical for single-phase outgoing circuits in TN or TT earthing systems.
Schneider Electric lists the C60HC20R100 as obsolete.
