The thermal magnetic mechanism in the BAB2125V provides both instantaneous magnetic tripping for short circuits and thermal overload protection for gradual faults, delivering fast fault interruption and minimizing heat buildup in panels. Business impact: enhanced equipment protection and reduced risk of fire or insulation damage, translating to higher uptime in manufacturing lines. Application: ideal for 120/240 V circuits in industrial control panels where reliable, code-compliant protection is essential. The two-pole bolt-on mounting simplifies retrofits and new installs, cutting installation time and labor costs while ensuring solid mechanical contact and consistent performance. Business impact: faster commissioning and easier maintenance in retrofit projects and aftermarket upgrades. Application: suitable for panel upgrades in machine rooms and control cabinets with standard bolt-on frames. The 10 kAIC interrupt rating supports high fault currents typical in industrial facilities, delivering a robust safety margin. Business impact: greater fault tolerance and improved selectivity with downstream protection devices, reducing nuisance trips during startup. Application: applies to motor drives and power distribution legs in manufacturing lines. HACR-rated and UL Listed/ CSA Certified credentials provide regulatory confidence, helping meet electrical codes and customer requirements. Business impact: simplifies compliance audits and procurement workflows. Application: preferred for OEM assemblies and service contracts across motor control and automation applications. The compact bolt-on design, weighing about 0.5 lb, and dimensions of 5 in L x 3 in W x 1 in H support tight spaces without compromising protection. Business impact: enables more efficient panel density and reduced enclosure costs. Application: useful in compact MCCs, electrical enclosures, and control panels where space is at a premium.
