Description:

The EDB14040 is a one-pole, 40-amp E-Frame circuit breaker used for overload and short-circuit protection in Square D NF lighting panelboards. Common applications include commercial lighting, heating and air-conditioning equipment, high-intensity-discharge lighting, and other 120- or 277-volt branch circuits.

Schneider Electric is the original manufacturer under the Square D brand. The EDB14040 remains in production and is listed by Schneider Electric as normally stocked through its distribution network. It uses a bolt-on bus connection and includes a Visi-Trip indicator that makes a tripped breaker easier to identify.
