Siemens 5SL3613-6 SENTRON MCB — 4-pole B-curve 13 A
The Siemens 5SL3613-6 is a SENTRON miniature circuit breaker (MCB) in the 5SL3 design, 4-pole (3P+N), with a B tripping characteristic and a 13 A rated current at 400 V AC. The B-curve trips at 3–5× rated current, which catches short circuits fast enough for most lighting and general-purpose branch circuits without nuisance trips from inrush. The 4-pole module takes 4 width units (72 mm total) and needs 70 mm of installation depth behind the panel. Wire range accepts solid or stranded conductors from 0.75 mm² up to 25 mm², with a tightening torque of 2.5 to 3 N·m on the screw terminals. It's sealable, halogen-free, and silicon-free — relevant if the panel sits in a cleanroom or food-processing environment where outgassing matters. The neutral pole switches with the phase poles, which simplifies panel wiring for single-phase loads fed from a 3-phase distribution board.
