45A B Curve MCB 6kA One Pole Miniature Circuit Breaker for Residential and Light Commercial Panels

The 45A B-Curve MCB is a single-pole miniature circuit breaker designed for dependable overcurrent protection in electrical panels. Ideal for residential and light commercial circuits, it combines a precise B-curve trip profile with a robust 6kA breaking capacity to safeguard wiring and appliances.

• Current rating: 45 A nominal, protecting branch circuits
• Trip curve: B-Curve thermal-magnetic characteristics for fast response to short circuits
• Breaking capacity: 6 kA to safely interrupt fault currents
• Poles: 1P (single-pole) configuration
• Application: Suitable for standard distribution boards and panel installations

By selecting this MCB, you gain reliable, predictable protection that minimizes nuisance trips on normal inrush while ensuring quick isolation during faults. It helps preserve wiring insulation, reduces the risk of electrical fires, and simplifies panel maintenance with a straightforward reset after tripping. It's a practical choice for upgrading older panels or wiring new circuits where a 45A, single-pole protection is appropriate.
