Product details

The Schneider Electric A9GSB750 is a 3P+N fuse-disconnector from the Acti9 SBI range, rated for 690 V AC operational voltage and accepting fuse links sized 14 x 51 mm. It carries the AM GG fuse curve — general-purpose gG class for cable and motor protection — and is built to IEC EN 60947-3, the standard for disconnectors and switch-disconnectors. Rated current is selectable across 10 A, 12 A, 16 A, 20 A, 25 A, 32 A, 40 A, and 50 A — the same hardware accommodates the full range by fitting the appropriate fuse link. That makes it a single SKU for a panel builder stocking one fuse-disconnector body across multiple branch circuits.

Tightening torque is 2.2 N·m; strip length 10 mm. The 106 mm width and 107 mm height fit standard distribution boards; depth is 70 mm, so it clears shallow enclosures.

Frequently asked questions

What is A9GSB750's listed depth?

The A9GSB750 has a depth of 70 mm, which fits standard shallow enclosures.

What is the closest pin-compatible alternative to A9GSB750?

Within the Acti9 SBI range, the A9GSB750 is the 3P+N 50A variant. Other pole configurations (1P, 2P, 3P, 4P) and current ratings share the same 14x51 mm fuse format and DIN footprint, but the 3P+N layout is specific to this order code.

What compliance documentation does Schneider provide for A9GSB750?

The A9GSB750 is certified to IEC EN 60947-3. Schneider Electric typically provides RoHS and REACH declarations for Acti9 products; specific documentation is available on request with an RFQ.

Where can I buy A9GSB750 and how is it quoted?

The A9GSB750 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
