16A Single Pole B Curve MCB Circuit Breaker for Residential and Light Commercial Panels

The 16A Single Pole B Curve MCB is a compact, dependable circuit breaker designed to protect a single live conductor in residential and light-commercial electrical panels. It delivers fast, predictable protection against overloads and short circuits without complicating installation.

• Current rating: 16A nominal current for standard lighting and outlet circuits
• Pole configuration: Single-pole (1P) design protecting one live conductor
• Trip curve: Type B curve for fast response to overcurrents, with instantaneous trip typically around 3–5× the rated current
• Protection mechanism: Thermal-magnetic trip providing both overload and short-circuit protection
• Application: Suitable for standard low-voltage distribution boards in homes and small offices
• Installation considerations: Designed for straightforward replacement in compatible panels and enclosures

With this 16A MCB in your panel, circuits automatically disconnect when current exceeds safe levels, protecting wiring from overheating and reducing the risk of fire. The Type B curve delivers a swift response to typical overcurrents, such as short circuits or power surges, while avoiding nuisance trips during normal startup. Its single-pole design protects one live conductor, making it ideal for lighting circuits, outlets, and small-appliance circuits in residential and light-commercial settings. Easy to replace or upgrade in compatible distribution boards, it supports safer, more reliable electrical protection with straightforward testing and reset when safe to do so.
