What this MCB does on the panel
The Schneider Electric C60H1P25AB is a 1-pole miniature circuit breaker from the Multi9 C60H range, rated 25 A at 30 °C with a B-curve magnetic trip threshold of 3 to 5 times In.
Breaking capacity and fault clearing
The C60H1P25AB carries a 15 kA Icu at 230…240 V AC (IEC 60947-2), which is the headline fault-clearing number for a 230 V distribution panel. At 400…415 V AC the Icu drops to 4 kA — still adequate for most sub-distribution boards but worth noting if the breaker sits on a 400 V bus. Rated impulse withstand voltage is 6 kV, covering typical transient overvoltages in industrial environments.
Integration into a distribution board
The toggle provides local ON/OFF indication and a contact position indicator confirms the state of the main contacts — useful during panel commissioning or fault finding when the breaker is locked out. The operating temperature range is -25 to 60 °C, storage -40 to 70 °C, with 95% relative humidity at 55 °C (tropicalisation class 2 per IEC 60068-1).
