Garo 40A Curve B 6kA MCB – 40A Single-Pole Circuit Protection
A practical option for circuits designed for a 40A protective rating. The Garo 40A Curve B 6kA MCB is a DIN-rail mounted, single-pole miniature circuit breaker rated at 40A, with a 6kA short-circuit breaking capacity. It provides overcurrent protection against overloads and short circuits in appropriately designed electrical installations.

Curve B Tripping Characteristic
Confirm circuit impedance and fault current before selecting this rating. The typical instantaneous magnetic tripping band for a Curve B MCB is 3–5 times its rated current; confirm suitability using the manufacturer’s published characteristics and the installation design.
Selection and Installation
Check the design current, conductor protection, prospective fault current, disconnection requirements and compatibility with the specific distribution board. An MCB does not itself provide residual current protection. Installation and device selection should follow BS 7671 and the manufacturer’s instructions.
Explore Garo circuit protection devices or compare Garo RCBOs where combined residual current and overcurrent protection is needed.
