The Schneider Electric A9N61522 is a 2-pole, 2 A, C-curve Acti9 C60H-DC miniature circuit breaker rated for 500 V DC circuits. It is a DC-dedicated device that protects DC control and auxiliary circuits, instrumentation and low-current solar PV or battery branches against overload and short circuit, with a thermal-magnetic trip conforming to IEC/EN 60947-2. Because it is engineered to break DC fault arcs, it must not be substituted with a standard AC MCB on the DC side of a system.
The A9N61522 provides overload and short-circuit protection on the direct-current side of a system. Typical uses include DC control, auxiliary and signalling circuits, instrumentation, sensor and battery supplies, and low-current solar PV string or battery branches where the operating voltage is up to 500 V DC.
Connection polarity is marked on the front of the breaker, and the two poles must be wired in series to protect a single DC circuit at the full 500 V DC rating. It accepts Acti9 auxiliaries and remote-signalling options; note that DC residual-current protection is handled by a separate device rather than a standard AC Vigi block, so confirm the correct DC-rated accessory with our engineer.
Electrical Junction is a Dubai-based distributor of genuine Schneider Electric, ABB and Lovato switchgear, sourced through our global sourcing hub across Asia and Europe. DC solar protection is a category we handle daily, so specification questions reach an engineer rather than a ticket queue.
What circuits is the A9N61522 used for?
The A9N61522 is a DC-only miniature circuit breaker rated for 500 V DC and 2 A, used to protect small DC circuits such as DC control and auxiliary circuits, instrumentation, and low-current solar PV or battery branches. Because it is designed to break DC fault arcs, which behave very differently from AC arcs, it must never be replaced with a standard AC MCB on the DC side of a system.
What is the breaking capacity of the A9N61522?
The A9N61522 has a rated breaking capacity of 6 kA at 500 V DC, and up to 10 kA at 440 V DC, conforming to IEC/EN 60947-2. This is the maximum DC fault current it can safely interrupt, so confirm the prospective short-circuit current of your DC source stays within this rating.
Why is a 2-pole breaker used for a single DC circuit?
On direct current the two poles are connected in series so the breaker can interrupt and extinguish the DC arc across the full 500 V DC rating. Using both poles in series is what allows the C60H-DC to safely break DC faults that a single pole or an AC MCB could not.
Can I use the A9N61522 on an AC circuit?
No. The A9N61522 is a DC-dedicated breaker and should be used on DC circuits only. It is optimised for breaking DC arcs; for AC circuits use the equivalent AC-rated Acti9 MCB instead. Our engineer can advise the correct AC or DC device for your application.
Can you supply and ship the A9N61522 to Saudi Arabia and the GCC?
Yes. Electrical Junction dispatches genuine Schneider Acti9 breakers from Dubai across the UAE and GCC, including Saudi Arabia. Every shipment includes standard export paperwork such as the commercial invoice, packing list and certificate of origin, and we provide the manufacturer datasheet and product technical documents. SABER conformity registration is completed by the importer of record in Saudi Arabia; we support that with the documentation you need. Contact our team for quotes and lead times.
