Description
Mini Circuit Breaker 125A 2 Pole 120/240VAC 10kA Plug-In Mount
Features
- Rated for a substantial 125 Amps at 120/240V AC, this 2-pole miniature circuit breaker is engineered to safely feed large residential sub-panels, workshop feeds, or dedicated commercial machinery. For residential contractors and property owners, this provides the robust current capacity needed to run modern multi-load applications without risking nuisance tripping or heat-related fatigue on main panel links.
- Equipped with the signature Square D Visi-Trip visual indicator flag, this breaker displays a highly visible, bright red window the moment an overcurrent or short circuit occurs. Homeowners and maintenance personnel can immediately spot the specific faulted line out of a dense cluster of switches, completely removing the guesswork and saving time during diagnostic troubleshooting.
- Featuring a dedicated 2-space plug-on mounting design, this premium breaker snaps directly onto the busbar of Square D QO load centers, and Speed-D switchboard distribution interiors. The precision-molded casing guarantees a tight, vibration-resistant electrical contact that eliminates loose-joint arching risks, though it will not physically fit into Homeline or competitor brand panels.
- Engineered with a fixed thermal-magnetic trip technology over-center mechanism, this unit features a quick-make, quick-break action that snaps open faster than the blink of an eye during a dead short. This rapid intervention significantly minimizes arc flash energy and prevents intense electrical spikes from traveling downstream, protecting expensive household electronics, server stacks, or HVAC compressors.
- Carrying comprehensive CSA and UL listings along with an official HACR rating, this device is certified to handle the high inductive inrush currents produced by heating, air conditioning, and refrigeration equipment. The breaker is built to function flawlessly up to an ambient temperature rating of 40 C (104 F) while meeting strict Canadian Electrical Code guidelines for long-term safety validation.
- Built with heavy-duty box lug terminals, this assembly safely anchors copper or aluminum wires ranging from 4 AWG up to 2/0 AWG. Tightening the terminal pressure screws to the manufacturer-specified torque of 49.56 lbf-in (5.6 N-m) ensures optimal, code-compliant physical clamping that keeps connection resistance low and eliminates hot spots caused by cyclical thermal expansion.
