Two Pack One Pole 40 Amp Miniature Circuit Breaker MCB C40 For 120V 240V AC With Thermal Magnetic Trip DIN Rail Mount Heavy Duty Built For The Long Haul Protection Against Overloads And Short Circuits
✔️ 40A single-pole MCB with thermal-magnetic trip, DIN-rail, two-pack
The two-pack 40 A miniature circuit breaker (MCB) protects 110-120V and 220-230V AC circuits from overloads and short circuits, and it also serves control and isolation roles. It uses curve C magnetic trip and mounts on a 35 mm DIN rail with screw terminals. This rugged unit is commonly used in solar AC systems, RVs, and household panels on 50/60 Hz networks.
✅ 40 A rated current for single-pole protection
✅ Curve C magnetic trip (5 to 10x) for fast fault isolation
✅ Silver alloy contacts with flame-retardant housing
✅ Color-coded indicators for quick status checks
✅ Screw terminals on 35 mm DIN rail mounting
✅ Pack: two units
