Description
Mini Circuit Breaker, 40A, 3 Pole, 120/240VAC, 10kA Breaking Capacity
Features
- Specifically designed for Square D QO load centers, NQ panelboards, and speed-D switchboard distribution panels, this 3-pole breaker features the industry-preferred plug-on design. This ensures a fast, secure connection to the bus bar without the need for complex mounting hardware, making it the go-to choice for commercial contractors and industrial maintenance teams.
- Featuring Schneider s exclusive Visi-Trip indicator, a high-visibility red window appears the moment the breaker trips. This "set it and forget it" diagnostic tool saves critical time during facility troubleshooting by instantly distinguishing a tripped breaker from one that has simply been turned off, allowing for rapid power restoration.
- Carrying a dedicated HACR (Heating, Air Conditioning, and Refrigeration) rating, this unit is factory-tested to handle the high inrush currents typical of compressor-based machinery. This rating ensures long-term durability and prevents nuisance tripping during equipment startup, maintaining consistent climate control in professional environments.
- Equipped with robust box lugs, this breaker accommodates #8 to #2 AWG copper or aluminum wire with a consistent, high-torque clamping force. These professional-grade terminals minimize electrical resistance and heat buildup at the connection point, ensuring your industrial installation remains code-compliant and fire-safe for years to-come.
