The Square D EDB24030 is a 2-pole, 30A, 480/277V bolt-on MCCB from the EDB (ED-frame) series, rated at 18kA interrupting capacity. As a molded-case circuit breaker, it is designed for installation in commercial and industrial panelboards and switchboards that accept ED-frame bolt-on breakers — not residential loadcentres.

  • Suitable for Square D NF, I-Line, and compatible bolt-on panelboards accepting ED-frame devices
  • Rated for 480/277V AC systems — common in commercial lighting, HVAC, and branch circuit protection
  • Verify your panelboard's frame acceptance and bus rating before installation — send us your panel model and we'll confirm compatibility

The EDB24030 is an ED-frame bolt-on MCCB rated for commercial and industrial panelboards and switchboards that accept Square D ED-frame devices at 480/277V. It is not designed for residential loadcentres. Send us your panelboard model number and we'll confirm the fit.

The Square D EDB frame series has been superseded in some applications by newer MCCB lines, making certain variants increasingly hard to source through standard channels. Northern Breaker Group specializes in obsolete and hard-to-find breakers — contact us for current stock availability on the EDB24030.

The EDB24030 is rated for 480/277V AC systems, so it is suitable for use on lower-voltage systems (such as 208V or 240V) as the voltage rating represents the maximum. However, always verify that the interrupting rating (18kA) meets or exceeds the available fault current at your installation point, as required by the Canadian Electrical Code (CEC).
