40A Single Pole B Curve MCB For Residential And Light Commercial Panels Compact Miniature Circuit Breaker

40A Single Pole B Curve MCB is a compact miniature circuit breaker designed to protect a single electrical circuit in residential or light commercial panels. It combines a 40-amp rating with a B-type trip curve for predictable protection against overloads and short circuits.

• Current Rating: 40A
• Pole: Single-pole (1P) design for one circuit
• Trip Curve: B-type curve for fast response to typical fault currents
• Trip Mechanism: Thermal-magnetic trip to interrupt fault currents quickly
• Application: Suitable for residential and light commercial panels needing reliable overcurrent protection

With this MCB, you get reliable, targeted protection that helps prevent overheating, damage, and fire risk from overcurrent events. The B-curve characteristic provides a balanced response—fast enough to clear faults without causing unnecessary trips on normal load fluctuations. The 40A rating makes it appropriate for circuits that require higher protection than a typical lighting circuit but still fit within a standard electrical panel. Its single-pole design simplifies installation, resets quickly after a trip, and integrates with other standard breakers to maintain a clean, safe electrical system.
