It also carries a 15 kA DC rating at 60 V (72 V max) per IEC 60947-2, and 5 kA per UL 1077. The 76 mm depth (70 mm installation depth) leaves clearance for standard 80 mm deep enclosures. IP20 with connected conductors; suitable for panel environments, not washdown zones. ## Environmental range Rated for -40 °C to 75 °C ambient, with humidity derating: 95% RH up to 55 °C, 55% RH up to 70 °C, 35% RH up to 75 °C. Mount in any position. Sealable to prevent tamper — useful for metering or critical circuits.","metaTitle":"Siemens 5SY4260-7 SENTRON MCB, 2P C-Curve, 10kA IEC/EN 60898","metaDescription":"Siemens 5SY4260-7 SENTRON 2-pole miniature circuit breaker, C-curve, 10 kA per EN 60898-1, 15 kA per IEC 60947-2.
