Siemens 5SL6116-7RC — 16 A, 1-pole C-curve MCB for residential and light commercial panels
The Siemens 5SL6116-7RC is a SENTRON miniature circuit breaker rated 16 A, single-pole, with a C tripping characteristic and a 7.5 kA breaking capacity per EN 60898. It occupies one modular width unit (18 mm) on a DIN rail, making it a direct drop-in for standard residential and infrastructure distribution boards. The C-curve means it trips between 5× and 10× rated current — suited for circuits with moderate inrush, like lighting groups, general-purpose socket outlets, and small motor loads where you need to ride through the starting surge without nuisance tripping.
Fit and panel integration
At 18 mm wide (1 MW), 76 mm deep, and 90 mm tall, this breaker fits any standard 35 mm DIN-rail enclosure. The 70 mm installation depth leaves room behind the busbar for wiring. IP20 with connected conductors means it's protected against finger contact once installed — standard for enclosed distribution boards. Rated for overvoltage category III and pollution degree 2, it's ready for fixed-installation mains supply points.
Electrical ratings and what they mean for your circuit
Rated 16 A at 230/400 V AC, 50/60 Hz. The 7.5 kA breaking capacity per EN 60898 is the fault current it can safely interrupt — adequate for most residential and light commercial service entrances where the prospective short-circuit current stays under that level. Single-phase operation at 250 V AC; multi-phase at 440 V AC maximum. DC rated up to 72 V, so it can also protect DC control circuits within that voltage limit. Power dissipation is 1.7 W per pole at rated current in hot state — negligible for thermal budgeting in a populated enclosure.
