This 2-pole, 70A molded case circuit breaker is purpose-built for branch circuit overcurrent and short-circuit protection. It’s ideal for electricians and facilities technicians who need a precise, compatible replacement or upgrade for Square D panelboards and load centers in a variety of environments—from home electrical panels to small business and light industrial electrical rooms.

Why this Square D breaker matters

The combination of a high-current rating, plug-in convenience, and a thermal-magnetic trip mechanism means you get fast service with consistent protection. When a 240V circuit experiences a surge or overload, the magnetic trip acts quickly to suppress faults, while the thermal element handles slower temperature-driven conditions. The result is dependable protection that helps prevent damage to wiring, outlets, and connected equipment.

Who it's for

Ideal for professionals upgrading panelboards, replacing worn breakers, or building out new electrical rooms where Square D load centers are standard. Suitable for residential circuits with higher-demand equipment, commercial lighting, and typical light industrial panel setups that require robust, reliable overcurrent protection.
