Schneider Electric Acti9 C60H-DC A9N61511 16A 1-Pole C-Curve DC MCB – 6kA, 250V DC
The Schneider Electric A9N61511 Acti9 C60H-DC is a 16A 1P C-curve DC MCB with 6kA breaking capacity at 250V DC, providing reliable overload and short-circuit protection for DC distribution, control and industrial applications.
Description
The Schneider Electric A9N61511 Acti9 C60H-DC MCB is a compact 16A 1-pole DC miniature circuit breaker engineered to protect direct-current electrical circuits against overload and short-circuit conditions. As part of the Acti9 C60H-DC range, it combines circuit protection, control and isolation in a compact solution for DC distribution and electrical control applications.
With a 16A rated current, C-curve thermal-magnetic protection, and 250V DC rated operational voltage, the A9N61511 DC MCB is suitable for low- and medium-current DC distribution and control circuits. Schneider Electric’s technical catalogue specifies a 6kA ultimate breaking capacity at 250V DC, 10kA at 220V DC, and 20kA at 110V DC for the 1P C60H-DC range.
The C-curve characteristic combines thermal protection for overload conditions with magnetic protection for short-circuit faults. This makes the Schneider A9N61511 16A DC MCB a practical choice for DC feeders, control panels, industrial automation and other suitable DC electrical systems where dependable circuit protection is required.
The A9N61511 is suitable for industrial isolation according to IEC/EN 60947-2. Schneider Electric also highlights its ability to combine short-circuit and overload protection, fast closing independent of toggle actuation speed, and compatibility with optional auxiliary devices, remote monitoring and other accessories.
The C60H-DC range supports comb-busbar installation, providing a flexible approach to electrical-panel assembly. Schneider’s documentation also specifies that C60H-DC breakers are polarised DC devices, so the manufacturer’s polarity requirements must be followed during installation.
For solar or photovoltaic DC applications, the complete system design should be checked carefully, including DC voltage, polarity, available fault current and applicable installation standards. Schneider’s technical catalogue classifies the C60H-DC as a DC circuit breaker and specifically notes polarity considerations for PV installations in certain markets.
