Schneider Electric Acti9 C60H-DC A9N61504 4A 1-Pole C-Curve DC MCB – 6kA, 250V DC

Description

The Schneider Electric A9N61504 Acti9 C60H-DC MCB is a compact 4A 1-pole DC circuit breaker designed for dependable protection of 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 functions in a compact DIN-rail-mounted device.

With a 4A rated current, C-curve characteristic, and 250V DC rated operational voltage, the A9N61504 DC MCB is well suited to low-current DC distribution, industrial control, automation and other applications requiring reliable DC circuit protection. Schneider Electric specifies a 6kA ultimate breaking capacity at 250V DC, with the C60H-DC 1P range also providing higher breaking capacities at lower DC voltages.

The C-curve thermal-magnetic protection provides protection against both overload and short-circuit currents. The C60H-DC range is specifically intended for DC circuits, and Schneider’s technical catalogue lists applications including industrial control and automation, transport and renewable-energy systems.

The Schneider A9N61504 also provides suitability for industrial isolation according to IEC/EN 60947-2. The device supports optional auxiliary functions, remote monitoring and compatible accessories, while comb-busbar compatibility helps simplify installation in suitable Acti9 systems.

For DC installations, correct polarity must be observed. Schneider’s technical documentation identifies the C60H-DC as a polarised DC circuit breaker, with supply possible from above or below while observing the specified polarity.

SEO note: Although the product URL may describe the A9N61504 as a solar DC MCB, Schneider Electric’s official classification is Acti9 C60H-DC MCB for DC circuits. For photovoltaic applications, suitability should be confirmed against the complete PV system design, polarity requirements and applicable installation standards.
