Description
Mini Circuit Breaker 70A 3 Pole 120/240VAC 10kA Plug-in Mount
Features
- Designed specifically for the premium Square D QO platform, this unit features a seamless plug-in mounting style that snaps directly onto standard QO load centers. This native compatibility eliminates field modifications and speeds up your field installation process while preserving the structural integrity of your enclosure.
- Engineered for demanding applications, this 70A, 3-pole miniature circuit breaker safely handles 240V AC to deliver robust, continuous power distribution. It is the ideal choice for safeguarding high-draw machinery, large commercial HVAC units, and heavy industrial three-phase loads.
- Equipped with the industry-exclusive Visi-Trip red indicator flag, a prominent visual marker instantly signals exactly which breaker has tripped in a crowded panelboard. This feature saves valuable troubleshooting downtime during facility maintenance, allowing electrical contractors to quickly isolate faults, reset the thermal-magnetic toggle, and restore operations.
- Featuring a high-performance 10 kAIC (10,000 Amperes Interrupting Capacity) short-circuit current rating, this thermal-magnetic breaker successfully interrupts dangerous electrical faults without failing catastrophically. This safeguards your expensive downstream machinery and heavy equipment from devastating overcurrent damage.
- Built with versatile pressure plate box lugs, this electrical component accommodates a broad wire size range from AWG 8 down to AWG 2 in either copper or aluminum conductors. The heavy-duty terminal design ensures high torque retention and a low-resistance electrical connection, minimizing localized heating and long-term joint degradation under maximum load.
- Fully CSA Certified and UL Listed as a standard miniature circuit breaker, this product complies with rigorous national safety mandates for Canadian commercial installations. Additionally, its official HACR rating ensures it is code-approved for the high inrush currents typical of heating, air conditioning, and refrigeration systems.
