Engineered for commercial applications, the Square D EDB24090 is a 90A, 2-pole molded case circuit breaker providing dependable thermal-magnetic protection. This E-Frame breaker installs into Square D NF panelboards via a secure bolt-on connection. It accepts 14-2/0 AWG copper or 12-2/0 AWG aluminum wire. Rated for 18kAIC at 480Y/277V, it includes the Visi-Trip indicator for rapid fault identification and is HACR rated for HVAC equipment.
What panelboards are compatible with the Square D EDB24090?
This E-frame circuit breaker is designed exclusively for use in Square D NF series panelboards. It features a bolt-on mounting style and will not fit NQ or I-Line panelboards.
What is the difference between Square D EDB, EGB, and EJB circuit breakers?
The difference lies in their interrupting ratings at 480Y/277VAC. EDB breakers are rated at 18 kAIC, EGB breakers are rated at 35 kAIC, and EJB breakers provide the highest rating at 65 kAIC. They share the same physical footprint and fit the same NF panelboards.
Is the EDB24090 circuit breaker HACR rated?
Yes, this breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment.
What is the recommended lug torque for the EDB24090?
The tightening torque depends on the wire size used. For 14-10 AWG conductors, torque the lugs to 34.5 lb-in. For larger 8-2/0 AWG conductors, torque to 49.6 lb-in.
Can I use an EGB24090 or EJB24090 to replace this EDB24090 breaker?
Yes. EGB and EJB breakers have the same physical dimensions and mounting style as the EDB series but offer higher interrupting ratings. They can be used as direct upgrades if a higher fault current rating is required.
