Identifying the proper controls for a lighting system can be a daunting task. Cost, space considerations, energy codes, desired operation, and NEC code compliance must all be considered when specifying a system. Often, controls for emergency lighting systems are also required which further compounds the complexity of the control system.

Powerlink ECB-G3EL circuit breakers relieve much of the burden associated with designing such control systems. These UL listed circuit breakers provide a means to comply with the requirements of the National Electrical Code, 700.12(E). The circuit breaker contains both a remotely operated switched circuit for controlling the luminaires, and a manually operated unswitched circuit, which provides power to the unit emergency equipment’s charging and detection circuit. Both circuits are electrically tied to the same source via a single common bolt-on connection that receives its supply from the panelboard bus.

Both circuits of the ECB-G3EL breaker contain a thermal-magnetic trip mechanism that protects their associated conductors from overcurrent. The circuit breaker also provides a common trip function ensuring both circuits will open whenever a fault occurs on either circuit and a common handle tie to ensure that both circuits are manually switched together.

Features

• With a 20A handle ratings,  these circuit breakers incorporate the same robust features as other Powerlink ECB-G3 breakers including:
• Suitable for use on 208Y/120V or 480Y/277V systems
• Interrupting Ratings: 65kA at 240Vac, 14kA at 480Y/277Vac
• Maximum Series Connected Ratings: 200KA at 240Vac and 100kA at 480Y/277V
• Rated Endurance On/Off/On cycles: 200,000 operations
• Breaker status viewing window for both circuits
• Auto/manual override selector for the remotely operated circuit
• UL listed Switch Duty Rated (SWD) and High Intensity Discharge (HID) ratings
• Lug wire size: (1) #12-8Al, #14-8Cu per circuit, 75°C conductors
• No breaker pigtails or other externally mounted hardware
