Air Circuit breaker Masterpact ACB NW25H1 - 2500 A - 3 poles - fixed Type.

Schneider Electric Masterpact NW25H1 Air Circuit Breaker – 2500A, 3 Poles, Fixed Type (Ref. 48070)

The Masterpact NW25H1 is Schneider Electric's high-current air circuit breaker frame, built for low-voltage power distribution boards carrying heavy industrial loads. This 2500A, 3-pole fixed-mount unit (reference 48070) ships as a bare frame without a trip unit, so it pairs with whichever Micrologic control unit your application requires. The H1 performance class is specified for sites with elevated short-circuit levels — such as plants running two transformers in parallel — rather than standard low-rise distribution. Full electrical ratings (Icw, durability, voltage, frequency) are listed in the specifications tab below.

Applications & Compatibility

• Main incomer or bus-tie protection in industrial LV switchboards
• Generator and motor protection circuits
• Installations with two parallel-connected transformers or elevated short-circuit levels (the H1 performance class)
• Accepts Micrologic A, E, P, or H series control units depending on the protection and communication functions needed — confirm the exact Micrologic reference with our team before ordering
• Fixed mounting only — cannot be field-converted to drawout; drawout requires a separately built NW25H1 drawout frame and cradle

Why Buy From Electrical Junction

Heavy frame components like the Masterpact NW25H1 carry long lead times and high landed costs through general distributors. We source directly through our own global sourcing hub, with import relationships across Asia and Europe — keeping pricing competitive and restocking faster than UAE-only resellers. Every export and international inquiry is reviewed by Ahamed Firdhous, our in-house engineer, who checks frame, trip-unit, and accessory compatibility before you place an order. UAE-based buyers who want to inspect a heavy industrial breaker like this in person before committing are welcome at our Dubai counter.

Frequently Asked Questions

Does this Masterpact NW25H1 (48070) come with a trip unit?

No — reference 48070 ships as a bare circuit breaker frame without a trip unit. You order a compatible Micrologic control unit (A, E, P, or H series) separately based on the protection and communication functions your application needs.

Can I convert this fixed-mount breaker to a drawout version later?

No — a fixed-mount Masterpact NW25H1 cannot be field-converted to drawout. The drawout version uses interlocks and a cradle assembly that aren't compatible with the fixed frame, so the mounting type must be decided before ordering.

What does the "H1" in NW25H1 mean for my installation?

H1 indicates a higher breaking-capacity performance class within the Masterpact NW range, intended for sites with elevated short-circuit levels — such as plants running two transformers in parallel — rather than a standard distribution board.

Is this a genuine Schneider Electric part, and where do you source it from?

Yes — we supply genuine Schneider Electric stock, sourced through our own global sourcing hub with import relationships across Asia and Europe, not grey-market or duplicated parts.

Can I get this shipped outside the UAE, and who handles technical questions for export orders?

Yes — export and international inquiries are handled directly by our in-house engineer, Ahamed Firdhous, who reviews frame and trip-unit compatibility before confirming your order.
