That dual-standard rating means it qualifies for both residential-distribution board applications (60898-1) and industrial panel use (60947-2), where the fault-current duty is higher and the breaker must interrupt without upstream coordination failure. The 100 A rated current at 30 °C is the continuous thermal-magnetic trip point — sized for a main feeder or a heavy subfeed in a 230 V single-phase AC network. ## D curve — magnetic trip characteristic The D curve defines a magnetic tripping threshold of 10 to 14 times the rated current (In), with a tighter 12 x In ±20 % under the 60947-2 standard. For a 100 A D-curve MCB, the instantaneous magnetic trip activates between roughly 1000 A and 1400 A, letting through the inrush without opening while still protecting against hard short circuits. Depth of 73 mm, height 81 mm. Tunnel-type terminals accept 1 to 50 mm² rigid cable or 1.5 to 35 mm² flexible, with a tightening torque of 3.5 N·m on the power circuit. The toggle handle provides local ON/OFF indication and a contact-position indicator confirms the state for isolation purposes — the breaker is marked suitable for isolation, meaning it can be used as a disconnection point under lockout/tagout procedure.","metaTitle":"Schneider Electric A9N19852 C120L MCB, 1P 100A D Curve, 15kA","metaDescription":"Schneider Electric A9N19852 Acti9 C120L miniature circuit breaker, 1P, 100A, D curve, 15kA breaking capacity.
