C-curve trips between 5× and 10× rated current (5–10 A for this 1 A unit), so it handles moderate inrush from small motor starters, contactor coils, or lighting ballasts without nuisance tripping. Two-pole switching (2P) means both line and neutral are disconnected on fault or manual isolation — required for single-phase final subcircuits in many national wiring rules. Frequency range is 50/60 Hz, so it works on either mains standard without derating. Sealable (can be locked in OFF position with a padlock) for lockout/tagout compliance.","metaTitle":"Siemens 5SL4201-7 SENTRON MCB, 2P C 1A 400V 10kA","metaDescription":"Siemens 5SL4201-7 SENTRON miniature circuit breaker, 2-pole, C-curve, 1 A, 400 V AC, 10 kA breaking capacity per EN 60898 & IEC 60947-2.

The 5SL4363-7 is a 3-pole unit (54 mm wide, 3 modular units), while the 5SL4201-7 is 2-pole (36 mm wide, 2 modular units). The DIN-rail mounting and 76 mm depth are the same, but the pole count and width differ — you would need to re-terminate the third phase and adjust the enclosure fill."},{"question":"Where can I buy 5SL4201-7?","answer":"Sourced and quoted to order against an RFQ through independent distribution.
