The Square D EJB36015 is a bolt-on molded-case circuit breaker (MCCB) rated 3-pole, 15 A, 600 V AC, 25 kA interrupting capacity. As an EJB-frame breaker, it is designed for installation in Square D panelboards and switchboards that accept the EJB bolt-on frame — typically industrial and commercial distribution equipment, not residential loadcentres. It is not interchangeable with Square D QO or Homeline plug-in residential breakers.
Panel compatibility depends on your specific Square D panelboard model and bus configuration. Send us your panelboard model number and we'll confirm fit before you order.
The EJB36015 carries a 25 kA interrupting rating at 600 V AC. This makes it well suited for commercial and industrial distribution panels where available fault current is at or below 25 kA. If your system's available short-circuit current exceeds 25 kA, you'll need a higher-rated frame. Contact our team and we can help you assess the right breaker for your fault-current requirements.
The Square D EJB frame series has seen limited availability through standard distribution channels. Northern Breaker Group specializes in hard-to-find and obsolete breakers — if the EJB36015 is discontinued or long lead-time through regular suppliers, we maintain stock of legacy Square D MCCBs and can source across our North American network. Request a quote and we'll advise on availability and condition.
A breaker rated at 600 V AC can be applied at any system voltage at or below that rating, including 208 V, 240 V, 480 V, and 600 V three-phase systems. The 15 A continuous current rating and 25 kA interrupting capacity apply; note that interrupting ratings can vary by voltage level, so always verify against your system's specific fault-current study. Our technical team is happy to assist.
