Industrial TB270 70A 2-Pole 240 V Circuit Breaker

Meet the Industrial TB270 70A 2-Pole 240 V Circuit Breaker — a rugged, dependable overcurrent protector engineered for demanding industrial environments. With a 70-amp rating and a two-pole design, it cleanly interrupts both hot lines on 240 V circuits, safeguarding wiring, motors, and equipment from overload and short circuits.

Designed for reliability in control panels, distribution boards, and industrial electrical gear, this TB270 unit provides precise protection where it counts. The 2-pole configuration ensures simultaneous disconnection of both conductors, reducing arc risk and helping maintain safe, predictable electrical behavior in demanding applications.

Key specifications

• Current rating: 70 A
• Poles: 2
• Voltage rating: 240 V
• Part number: TB270
• Application: industrial circuits requiring robust 240 V, two-pole protection

Why the TB270 stands out

• Dual-pole safety: Tripping both lines at once minimizes stray current paths and protects connected equipment more effectively than single-pole breakers in 240 V systems.
• Durable, industrial-grade design: Built to endure vibration, temperature variation, and continuous operation in workshop floors, factories, and maintenance environments.
• Clear replacement pathway: The TB270’s standardized form and part-number traceability simplify maintenance, inventory, and fast replacements in busy facilities.
• Predictable protection: Provides consistent, reliable overcurrent protection for circuits delivering high starting currents to motors, pumps, conveyors, and other 240 V loads.

Ideal for

• Electrical panels and distribution boards in manufacturing facilities
• Motor circuits and 240 V feeders feeding conveyors, pumps, and HVAC equipment
• Maintenance and service crews seeking a dependable replacement part for industrial gear

Practical considerations and tips

When selecting the TB270, match the amperage rating to the circuit load and ensure your panel is configured for 2-pole 240 V protection. Use appropriate enclosure labeling and follow standard electrical practices for mounting and wiring to ensure safe, compliant operation. If you’re replacing an existing breaker, verify that the TB270’s form factor and termination method align with your panel’s specifications to avoid compatibility issues.
