The Schneider Electric C60H3P25AC is a 3-pole C60H miniature circuit breaker from the Multi9 range, rated 25 A at 30 °C with a C trip curve (magnetic tripping between 5 and 10 times In). The C curve means it handles moderate inrush without nuisance tripping — typical for mixed resistive and light inductive loads in commercial or light industrial distribution. The thermal-magnetic trip unit gives you both overload protection (thermal bimetal) and short-circuit protection (magnetic solenoid) in one package.
This breaker carries a 10 kA Icu at 440 V AC per IEC 60947-2, and 15 kA Icu at 400–415 V AC. At the common 230–240 V level it jumps to 30 kA Icu. That matters for selectivity studies: you need the upstream device to hold while this one clears, and the 10 kA at 440 V gives you headroom in most 400 V distribution boards.
Physical integration and environment
Dimensions: 81 mm high, 54 mm wide (6 x 9 mm pitches), 73 mm deep. Fixed mounting on 35 mm DIN rail. The toggle gives clear ON/OFF indication and a contact position indicator confirms the state of the moving contacts. Earth-leakage protection is handled by a separate block — this is the plain MCB, not an RCBO.
