Designed specifically for 480Y/277V commercial and industrial distribution, this 15-amp E-frame component integrates a 120VAC shunt trip mechanism. It mounts securely into Square D NF panelboards, requiring four total pole spaces due to the added accessory module. The thermal-magnetic trip unit delivers reliable overload and short-circuit protection with an 18kAIC rating at 277V. Visi-Trip technology provides clear visual indication during fault events to minimize facility downtime.
What does the SA suffix indicate on the EDB34015SA catalog number?
The SA suffix denotes a factory-installed 120VAC shunt trip. This allows the breaker to be tripped remotely by an external control signal for safety or automation purposes.
How many panel spaces does the EDB34015SA require?
Although it is a 3-pole breaker, the factory-installed shunt trip requires one additional pole space. You will need four total available spaces in your Square D NF panelboard to mount this unit.
Can I field-install a shunt trip on a standard EDB34015 breaker?
No. Electrical accessories for Square D E-Frame breakers, including the 120VAC shunt trip, are factory-installed only. You must order the breaker with the SA suffix if remote tripping is required.
Can the EDB34015SA be used on a 480V ungrounded delta system?
No. The 480Y/277VAC slash rating means this breaker is only suitable for solidly grounded wye systems where the voltage to ground does not exceed 277V. It cannot be used on ungrounded or corner-grounded 480V delta systems.
Is the EDB34015SA compatible with Square D I-Line or QO panelboards?
No. This E-Frame breaker features a bolt-on connection designed exclusively for Square D NF series panelboards. It will not fit in I-Line, QO, or NQ panelboards.
Are the trip settings adjustable on the EDB34015SA?
No. This thermal-magnetic breaker features fixed long-time and fixed instantaneous trip elements. The trip curve cannot be adjusted in the field.
