Description
Mini Circuit Breaker 50A 2 Pole 120/240VAC 10kA Plug-in Mount
Features
- The Schneider Square D QO250 is a two-pole circuit breaker rated for 50 Amps and 120/240V AC. It is the standard heavy-duty solution for high-demand residential and commercial appliances, typically used to protect electric ranges, hot tubs, large central air conditioning units, and Level 2 EV charging stations.
- As part of the flagship QO (Square D) line, this breaker features a more compact 3/4-inch per pole width (1.5 inches total) and a higher build quality designed for both residential and demanding industrial environments. It is engineered for long-term reliability and is widely considered the industry benchmark for circuit protection.
- One of the most critical safety features of the QO250 is the integrated Visi-TripTM indicator. When the breaker trips due to a fault, a high-visibility red mechanical flag appears in a dedicated window on the breaker face. This allows homeowners and electricians to instantly identify the faulted circuit without guessing whether a handle is in the "off" or "tripped" position.
- This model features the standard QO plug-on connection, designed to snap securely onto the bus bar of any Square D QO load center or NQ panelboard. The high-pressure "jaw" design ensures a gas-tight, vibration-resistant electrical contact that maintains its integrity over decades of service.
- The QO250 utilizes a thermal-magnetic trip mechanism. It provides a time-delay for standard temporary surges (like an A/C compressor starting up) but offers instantaneous protection against high-energy short circuits with a 10kA interrupting rating (AIR). This prevents wire overheating and significantly reduces the risk of electrical fires.
