Square D EDB14030EPD 30A 277V 1-pole Molded Case Circuit Breaker

Product Description

The SQUARE D EDB14030EPD is a single-pole, thermal-magnetic molded case circuit breaker rated at 30 amps and 277 VAC. It is designed for panel mount installation in commercial and industrial electrical distribution systems. The thermal-magnetic trip mechanism provides dual protection: a bimetallic element responds to sustained overloads, while a magnetic element provides near-instantaneous response to short-circuit faults. The toggle-style reset actuator allows manual trip and reset operations at the panel face. Conductor entry is via lug terminals, accepting 12 to 4 AWG aluminum or 14 to 6 AWG copper wire. Licensed electricians are the primary trade for installation and service of this device.

The EDB14030EPD is suited for single-phase branch circuit protection in commercial lighting panels, HVAC disconnect applications, and industrial control panels operating at 277 volts AC. It is a panel-mount device intended for use where a 1-inch-wide, single-pole breaker position is required. The 277-volt rating makes it a common choice for single-phase loads derived from 480Y/277-volt three-phase distribution systems found in commercial buildings.

• Single-pole configuration for branch circuit protection
• Lug terminal connection accepts 12-4 AWG aluminum or 14-6 AWG copper conductors
• Toggle switch reset actuator for manual trip and reset at panel face
• Panel mount design for installation in compatible distribution panels

Compatibility

Designed as an OEM-style replacement molded case circuit breaker for compatible SQUARE D panel enclosures and distribution boards rated for EDB-series single-pole breaker positions.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NFPA 70 (National Electrical Code) and all applicable local codes. De-energize and lock out the panel before installing or replacing any circuit breaker. Verify that conductor size and insulation rating match the terminal specifications before torquing lug connections. Do not exceed the breaker ampere rating with connected load.
