Product details

The Schneider Electric A9L16578 is an Acti9 iPRD8r modular surge arrester — a Type 2 + 3 MOV-based unit for 400 V AC distribution networks in IT earthing systems. It covers three poles (3P) with a maximum continuous operating voltage of 460 V L/PE and a nominal discharge current of 2.5 kA common mode, peaking at 8 kA common mode for the maximum discharge. This is an obsolete part per the manufacturer's lifecycle status.

Marked obsolete by Schneider Electric. No official successor order code is listed in the lifecycle record.

Frequently asked questions

Where can I buy A9L16578?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing confirmed at quote time.

What standards does A9L16578 comply with?

It complies with EN 61643-11 and IEC 61643-11 for surge protective devices.

What is the closest alternative to A9L16578 in the Acti9 family?

No official successor is listed. A functionally similar current-production Acti9 iPRD unit would need to match the 3P, 460 V MCOV, Type 2+3, and remote signalling — verify the order code against your panel's voltage and earthing system (IT).
