The Q1-250 50A is a two-pole breaker built to handle the demands of everyday electrical maintenance, whether you're working in a home panel or light commercial setup. It's rated for 50 amps and designed with both thermal and magnetic trip technology — which basically means it can quickly shut things down if there's an overload or short circuit. It fits neatly into four panel spaces and installs easily with a plug-on setup, making it a smart choice when you're upgrading or replacing breakers without wanting to rework your whole system.
