At 0.3 A, this is a low-current MCB sized for control circuits, not main power feeds. The 6 kA breaking capacity is the same under both EN 60898 (household) and IEC 60947-2 (industrial) standards, so the part can be specified in either context without a separate rating check. The maximum operating voltage is 440 V AC for multi-phase operation, and the DC rating is 72 V maximum. Thermal derating is published: 0.3 A at 30 °C, 0.28 A at 40 °C, 0.27 A at 45 °C, and 0.25 A at 55 °C. ## Mechanical and environmental fit The 5SL6214-7 occupies 2 modular width units (36 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm. The IP20 rating applies only with connected conductors — the terminals are touch-protected per the product feature. Sealable per the spec, allowing lockout/tagout compliance.","metaTitle":"Siemens 5SL6214-7 SENTRON MCB, 2-pole C-curve 0.3 A, 6 kA","metaDescription":"Siemens 5SL6214-7 SENTRON miniature circuit breaker, 2-pole, C-curve, 0.3 A rated current, 6 kA breaking capacity per EN 60898 and IEC 60947-2.
