Providing high-capacity protection for commercial facilities, the Square D EDB24100 is a 100A, 2-pole circuit breaker. This E-Frame device safeguards electrical systems against overloads and short circuits. It installs into Square D NF panelboards via a reliable bolt-on connection. The breaker comes equipped with lugs that accept up to 2/0 AWG wire. With an 18 kAIC rating at 480Y/277V, it utilizes fixed thermal-magnetic trip technology and features an integrated Visi-Trip indicator.
Which panelboards are compatible with the EDB24100 circuit breaker?
The EDB24100 is an E-Frame circuit breaker designed specifically for use in Square D NF panelboards. It features a bolt-on connection to mount directly to the panelboard bus.
Can I upgrade the EDB24100 if the electrical system requires a higher interrupting rating?
Yes. The standard EDB series provides an 18 kA interrupting rating at 480Y/277V. If higher short-circuit protection is required, you can cross-reference to the EGB24100 for 35 kA or the EJB24100 for 65 kA. Both alternatives share the exact same E-Frame footprint and bolt-on compatibility for NF panelboards.
Is the Square D EDB24100 HACR rated?
Yes, this breaker is HACR rated, meaning it is certified for use as overcurrent protection for heating, air conditioning, and refrigeration equipment.
What are the lug tightening torque specifications for the EDB24100?
The required torque depends on the wire gauge being terminated. For 14 to 10 AWG conductors, torque the lugs to 34.5 lb-in. For larger 8 to 2/0 AWG conductors, torque the lugs to 49.6 lb-in.
What are the instantaneous trip current values for this 100A breaker?
The fixed thermal-magnetic trip unit on the EDB24100 has a hold current of 1000A, which is the maximum inrush current the breaker will hold without tripping. The trip current rating is 2300A, the threshold at which the instantaneous mechanism is guaranteed to clear the fault.
Are the factory lugs on this breaker rated for aluminum wiring?
Yes, the breaker is supplied with factory-installed aluminum lugs that are dual-rated for both aluminum and copper. They accept 12 to 2/0 AWG aluminum conductors or 14 to 2/0 AWG copper conductors.
