MCB (Miniature circuit breaker) is a re-settable device designed to protect a circuit from short circuits and overcurrents. Trip curves of MCB’s (B, C, D, K and Z curves) tell us about the trip current rating of Miniature Circuit breakers. Trip current rating is the minimum current at which the MCB will trip instantaneously.

J-Type breakers are available in ‘B’, ‘C’ or ‘D’ curves for Single pole MCB’s and in ‘C’ or ‘D’ curves for Double and Triple pole. All J-Type MCB’s are rated at 6kA short circuit capacity. The tripping characteristics are shown to the right. ‘B’ Curve to BSEN 60898 (Magnetic Trip 3 to 5 Times In) Typically used in
Circuit breakers are divided into types based on their instantaneous tripping current. This is the minimum current at which the circuit breaker will discontinue the flow of electricity, or trip. It does this to protect devices plugged into the circuit from sudden rises in levels of current.

The most common curves are B, C, and D. One MCB manufacturer also produces a K and Z curve. B curve breakers: Trip between 3-5 times rated current in a short circuit situation. B curve MCBs should be applied where loads are resistive and do not have in-rush current. The breakers are still thermal-magnetic. They have a thermal trip curve as well as an instantaneous magnetic trip. The thermal part of the trip curve is basically the same for all of them. You are right the specifications (b,c,d,k) are indicative of the instantaneous trip point. Showcasing our curated selection of mount circuit breaker here.

VisiSafe : for safe operation and maintenance work on circuits. Large choice of breaking capacities up to 100 kA and tripping curves: B, C, D, Compliance with standards IEC/EN 60898 or IEC/EN 60947-2. The B,C,D,K,Z indicates the instantaenous tripping current. It means the minimum value of current causes the circuit to trip without intentional time delay. approximately < 100ms. Consider Rated Current be : (In) Instantaenous tripping current for C Curve is 5-10 times the rated current(In). Instantaenous tripping current for D Curve is 10-20 times
The circuit breaker’s trip curves consist of two parts: Tripping of overload protection (thermal tripping device) : The higher the current, the shorter the tripping time Tripping of short-circuit protection (magnetic tripping device) : If the current exceeds the threshold of this protection device, the breaking time is less than 10 milliseconds.
