Square D EHB14020AS Circuit Breaker

The AS suffix designates this unit as a Powerlink remote-control circuit breaker. Unlike standard EHB breakers, it includes internal mechanisms that allow it to be remotely switched on and off when integrated into a Square D Powerlink lighting control system.

No. The EHB14020AS is designed exclusively for legacy NEHB panelboards and Powerlink systems. Modern NF panelboards require EDB, EGB, or EJB series circuit breakers.

No, the Square D EHB series, including the EHB14020AS, is a legacy product line that has been discontinued. It was originally designed for NEHB panelboards, which have since been replaced by the NF panelboard series.

Because of its Powerlink remote-control capabilities, this breaker is primarily used in commercial and industrial lighting control systems. It allows facility managers to automate lighting schedules and manage energy loads directly at the panelboard level.

Yes. To utilize the remote-control functionality, the breaker must be connected to the Powerlink control bus strips within the panelboard. This allows the system controller to send the low-voltage signals required to mechanically open or close the breaker contacts.

Yes, despite being a remote-control breaker, the EHB14020AS retains a standard toggle handle. It can be manually switched ON or OFF by an operator just like a conventional thermal-magnetic circuit breaker.

Interrupting capacity depends on the system voltage. At 120VAC, the breaker can safely clear fault currents up to 65,000 amps (65kAIC). At its maximum rated voltage of 277VAC, the higher electrical potential reduces its maximum fault-clearing capacity to 14,000 amps (14kAIC).

Yes, standard handle padlocking attachments can be used to lock the breaker in the OFF position for safe maintenance. However, because it is a remote-control breaker, ensure the Powerlink control circuit is also properly isolated during servicing to prevent unexpected automated switching.
