2-Pole Circuit Breakers

2-Pole Circuit Breakers — New & Used

2-pole circuit breakers are essential electrical protection devices that safeguard 240 V single- or split-phase circuits by interrupting both hot legs simultaneously. They protect equipment, motors, lighting, and branch circuits from overloads, short-circuits, and ground-faults, ensuring safe and reliable operation of residential, commercial, and light-industrial systems.

At Surplus Select, we offer a variety of new and used OEM 2-pole breakers — including molded case and thermal-magnetic breakers — across a range of current and voltage ratings. Surplus pricing gives electricians, facility managers, and maintenance teams access to dependable overcurrent protection devices affordably, ideal for retrofits, panel upgrades, or spare inventory.

Fast U.S. Shipping — Most orders ship same or next business day to keep your projects and installations on schedule.

Find Your 2-Pole Breaker Fast (Search-First)

Search by breaker model number or specs (e.g., 2-pole 60 A breaker, 240 V MCCB 2P, 2P circuit breaker used).
No model number? Try general terms such as “2-pole 100 A breaker”, “240 V breaker surplus”, or “split-phase panel breaker”.
Refine by voltage rating, current rating, breaker type (MCCB, thermal-magnetic, etc.), or manufacturer for precise results.
