Physical footprint: 54 mm wide (3 modular width units), 90 mm tall, 76 mm deep, with a 70 mm installation depth. That's a standard 3-module DIN-rail mount — it clips onto the rail and occupies three adjacent 18 mm slots. The terminal accepts solid conductors up to 35 mm², sized for the feed-through of larger branch circuits. Operating temperature range covers -40 °C to 75 °C, which is wide enough for unheated electrical rooms or outdoor enclosures in most climates. Mechanical service life is typical 10,000 operating cycles — adequate for distribution duty where the breaker is cycled infrequently. The 70 mm installation depth means it fits flush in most distribution boards without protruding beyond the door clearance.","metaTitle":"Siemens 5SN6306-7CP MCB, 3-pole C-curve, 6kA/30kA","metaDescription":"Siemens 5SN6306-7CP SENTRON MCB, 3-pole, C-curve, 6kA per EN 60898, 30kA per IEC 60947-2.
