The Square D FH26090AC is a bolt-on, 2-pole, 90A, 600/347V, 18kA moulded-case circuit breaker in Square D's FH frame. This is an industrial/commercial-grade MCCB rated for 600V AC, designed to mount in compatible Square D panelboards and switchboards — it is not a residential loadcentre breaker. It is suited for commercial, industrial, and light-industrial distribution panels that accept FH-frame bolt-on devices.
Panel fit depends on your specific switchboard or panelboard model and busbar configuration. Send us your panel model and we'll confirm compatibility.
The FH26090AC is an FH-frame, bolt-on MCCB rated 600/347V — it is designed for Square D commercial and industrial panelboards and switchboards that accept FH-frame devices, not residential QO or Homeline loadcentres. Because fit depends on your specific enclosure and busbar, we recommend sending us your panel model number so we can confirm compatibility before you order.
The FH26090AC is rated 600/347V and configured as a 2-pole breaker, making it suitable for single-phase 600V or 347V AC applications (Phase I line). It is not a 3-pole device. If your application requires three-phase protection, a 3-pole FH-frame variant would be required — contact us and we can help identify the right breaker.
