Schneider Electric A9N61524 DC MCB - Acti9 C60H-DC - 2 Pole 4A C Curve

The Schneider Electric A9N61524 is a DC miniature circuit breaker from the Acti9 C60H-DC range, built to protect direct current circuits rather than standard AC installations. It is a 2-pole, 4A device with a C tripping curve and thermal-magnetic release, rated to 500V DC and offering 20kA Icu breaking capacity at 220 to 250V DC per IEC 60947-2. It is specified by panel builders and solar integrators who need a compact DIN-rail DC breaker with reliable arc interruption.

Applications and Compatibility

The A9N61524 is used wherever a DC circuit needs overload and short-circuit protection within a 500V DC ceiling: solar PV strings and combiner boxes, battery banks and UPS systems, DC control and automation panels, EV charging infrastructure, and transport and renewable energy installations. It mounts on standard 35mm DIN rail and accepts C60 accessories and auxiliaries. Because it is a DC-rated breaker, it is not interchangeable with an AC MCB of the same C60H frame.

Why Buy From Electrical Junction

• Genuine Schneider Electric parts, held in Dubai stock for same-region dispatch across the UAE and GCC.
• Export support to Saudi Arabia and Africa, including help with SASO and SABER conformity documentation for KSA imports.
• Technical queries handled directly by our engineer, so you can confirm voltage rating, pole configuration, and curve before you order rather than after.

Frequently Asked Questions

Is the Schneider A9N61524 a DC or AC circuit breaker?
The Schneider A9N61524 is a DC miniature circuit breaker, the Acti9 C60H-DC, rated for DC circuits up to 500V DC. It must not be used as a standard AC MCB, because a DC arc does not self-extinguish at a zero crossing the way an AC arc does.

What is the breaking capacity of the A9N61524?
The A9N61524 has a 20kA Icu rated ultimate breaking capacity at 220 to 250V DC per IEC 60947-2, reducing to 10kA at 440V DC and 6kA at 500V DC. Its rated service breaking capacity (Ics) is 15kA at 250V DC.

Can I use the A9N61524 on a solar PV system?
Yes. The A9N61524 is designed for DC circuits including solar PV strings and combiner boxes, provided your maximum system voltage stays within its 500V DC rating and you verify the string short-circuit current against its breaking capacity.

Why is the A9N61524 a 2-pole breaker with only 1 protected pole?
The A9N61524 wires both of its poles in series on a single DC circuit to safely break the DC arc, which is why Schneider lists it as 2-pole with 1 protected pole rather than as two independent circuits.

Do you deliver the A9N61524 to Saudi Arabia?
Yes. We stock the A9N61524 in Dubai and deliver across Saudi Arabia and the GCC, and we can help with the SASO and SABER conformity documentation needed for your KSA import.
