HJA36070 - 70 Amp Circuit Breaker

HJA36070 - 70 Amp Circuit Breaker

The HJA36070 is a PowerPact H-Frame molded case circuit breaker designed for your electrical distribution equipment that requires a 3-pole, 70-amp thermal-magnetic breaker with I-Line compatibility. This breaker provides a 25kA interrupting capacity at 600VAC and is intended for applications where matching the existing equipment specifications is important.

Key Features and Benefits

• 70-amp, 3-pole configuration – Designed for compatible three-phase electrical distribution systems.
• Thermal-magnetic trip protection – Provides overload and short-circuit protection through a thermal-magnetic trip unit.
• 600VAC rating – Suitable for systems requiring up to 600VAC operation.
• I-Line line-side connection – Designed for equipment using I-Line mounting and connection systems.
• Mechanical load-side lugs – Provide load connections for compatible installations.
• Push-to-trip function – Allows manual tripping from the breaker cover when needed.
• 80% continuous current rating – Designed for continuous current applications within specified limits.
• Dual-break rotating contacts – Designed to help reduce peak current during short-circuit events.
