EB3030L - 30Amp Circuit Breaker

EB3030L - 30 Amp Circuit Breaker

The EB3030L circuit breaker is a 30-amp, 3-pole thermal-magnetic breaker designed for use in electrical distribution systems that utilize EB-frame breakers. Built for compatibility with panelboards manufactured prior to 1989, this breaker provides dependable overcurrent protection by responding to both prolonged overloads and short-circuit conditions. The integrated thermal-magnetic mechanism features a non-interchangeable trip unit, ensuring that the breaker maintains its specified protection characteristics. With a 10kA interrupting rating at 240VAC and a 40°C operating rating, the EB3030L is suited for environments where consistent protection and proper panel compatibility are essential. Line and load terminals are included, supporting straightforward installation and reliable electrical connections. Like many breakers from this generation, it was engineered with durable components intended for long service life when properly installed and maintained.

Key Features and Benefits

• 30 Amp Current Rating: Provides overcurrent protection for circuits requiring a 30A capacity.
• 3-Pole Configuration: Designed for three-phase electrical systems where simultaneous disconnection across all phases is required.
• Thermal-Magnetic Protection: Combines thermal response for overload protection and magnetic response for short-circuit events.
• Non-Interchangeable Trip Unit: Factory-calibrated trip unit ensures consistent and fixed protection settings.
• 10kA Interrupting Capacity at 240VAC: Suitable for systems requiring this level of fault current interruption.
