EB1030 - 30Amp Circuit Breaker

EB1030 - 30 Amp Circuit Breaker

The EB1030 circuit breaker is a 30-amp, single-pole thermal-magnetic breaker designed for use in electrical panels that require the EB frame style used in systems manufactured prior to 1989. It provides branch circuit protection by responding to both sustained overload conditions and short-circuit faults through its built-in thermal and magnetic trip functions. The breaker features a non-interchangeable trip unit, meaning the trip characteristics are fixed and calibrated as part of the breaker itself. Rated for 10,000 A.I.C. at 120VAC, the EB1030 is intended for use in compatible legacy panelboards where the correct form, fit, and electrical rating are required. Load terminals are included to allow proper connection of conductors during installation. Like many breakers from this generation of electrical equipment, it was built with durable internal components intended for long service life when installed in the correct panel and used within its rated conditions.

Key Features and Benefits

• 30 Amp Rating – Designed to protect 120-volt branch circuits from overloads and short circuits.
• Single-Pole Breaker – Suitable for standard 120VAC circuit applications.
• Thermal-Magnetic Protection – Thermal response for prolonged overloads combined with magnetic tripping for instantaneous fault interruption.
• 10kA Interrupting Capacity – Rated to safely interrupt fault currents up to 10,000 amps at 120VAC.
• Non-Interchangeable Trip Unit – Trip calibration is built into the breaker for consistent operation.
• EB Frame Design – Matches the physical configuration required for EB-series panelboards.
• Load Terminals Included – Supports proper conductor termination during installation.
• 40°C Rated – Designed for operation in typical electrical equipment environments.

Material Compliance and Certifications

• Circuit breakers of this type are generally manufactured to align with UL safety standards for molded case circuit breakers used in North American electrical distribution systems. Proper installation in compatible equipment and adherence to electrical code requirements help maintain safe operation within the system.
  

Where It Works Best

• The EB1030 30A circuit breaker is typically used when maintaining or servicing electrical distribution equipment that was originally designed to accept EB-frame breakers. It helps keep older systems operating with the correct electrical ratings and physical configuration.
• Electrical panels installed before 1989 that require EB-series breakers
• Residential load centers still in service with EB frame compatibility
• Commercial panelboards using legacy EB breaker formats
• Branch circuits supplying lighting, outlets, or small electrical equipment
• Matching the original EB frame size and electrical rating helps ensure the breaker fits correctly within compatible panels while maintaining the intended level of circuit protection.
