20A Single Pole B Curve MCB For Residential And Light Commercial Panels And Circuits

The 20A Single Pole B Curve MCB is a compact, reliable overcurrent protection device designed for residential and light commercial electrical panels. It provides dependable circuit protection for a 20-amp branch circuit, helping keep wiring safe and protect connected devices.

• Rated Current: 20 A, matching common branch-circuit loads to protect wiring and devices.
• Pole Configuration: Single Pole, protecting a single live conductor in a circuit.
• Tripping Curve: B Curve, delivering a fast instantaneous trip on moderate overcurrents (typically around 3–5 In) to quickly isolate faults.
• Function: Overcurrent protection for dedicated circuits, reducing the risk of overheating and electrical damage.
• Application: Designed for standard low-voltage distribution panels in homes and small offices, enabling straightforward integration into existing setups.

With this MCB in place, fault currents are reliably interrupted to safeguard wiring and equipment. The single-pole design keeps installation simple and maintenance minimal, while the B-curve characteristic provides balanced protection for typical residential loads and common inrush scenarios without excessive nuisance trips. Ideal for protecting lighting circuits, outlet runs, and small-appliance circuits in homes and light commercial spaces. For best results, ensure compatibility with your panel and replace only with a breaker of the same type and rating.
