Miniature circuit breaker provides 3-pole thermal-magnetic protection for AC distribution circuits. It is rated for 125 A at 30 °C and uses a B trip curve with 3 to 5 times In magnetic tripping. Breaking capacity is 15000 A Icn at 400 V AC to EN/IEC 60898-1 and up to 15 kA Icu at 380 to 415 V AC to EN/IEC 60947-2. The DIN-rail mounted device has IP20 protection, toggle control, ON/OFF indication, and a 81 mm by 81 mm by 73 mm body. Operation is specified from -30 °C to 60 °C, with storage from -40 °C to 70 °C.
