Siemens Miniature circuit breaker, 1-pole, B-curve, 230/400V, 10A Part number 5SL4110-6

Product Overview

The Siemens 5SL4110-6 is the Siemens SENTRON 5SL4 Miniature Circuit Breaker, 1-pole, 10 A, B-characteristic. It provides reliable overload and short-circuit protection for single-phase circuits in residential, commercial or light-industrial electrical installations and distribution boards.

Key Features

• 1-pole miniature circuit breaker (MCB, 5SL4 series)
• Rated current: 10 A
• Tripping characteristic: B — suitable for general load protection (lighting, sockets, small loads)
• Rated operational voltage: 230/400 V AC (single-phase or multi-phase) — up to 440 V AC max
• Short-circuit breaking capacity: 10 kA (Icu / Icn) — meets standard protection requirements
• Energy-limiting class 3 — helps reduce fault energy during trips
• Screw-type terminals — accept solid or stranded conductors (typical range 0.75 … 25 mm²)
• Compact modular width (1-unit) — suitable for standard DIN-rail distribution boards or control panels
• Touch-protected terminals, halogen-free and silicon-free materials — safe for residential / commercial installations
• Sealable handle — can be locked in OFF position for safety or maintenance

Applications

The 5SL4110-6 is ideal for protection of single-phase circuits such as lighting, socket-outlet lines, small appliances, control circuits, and other low-to-moderate power loads. It is commonly used in residential distribution boards, commercial installations, small-scale industrial distribution, and as branch-circuit protection in panelboards or control cabinets. Its compact size and B-characteristic make it especially suited to general-purpose circuits where fast response to overloads and short circuits is required.
