This is the part to specify when you need a 2-module-width (36 mm) MCB for a residential or infrastructure distribution board, and the B-curve means it's sized for cable and general-purpose protection where inrush is low — lighting, socket outlets, control transformers.
The B-curve trips magnetically between 3 and 5 times rated current — so for a 6 A MCB, instantaneous trip starts at about 18 A and is guaranteed by 30 A. The 2-pole design switches both phase and neutral on a single-phase circuit, or two phases on a split-phase or two-phase system. The 36 mm width occupies 2 modular units on a DIN rail — standard for a 2-pole MCB in this series. The 76 mm depth plus 70 mm installation depth means it sits flush in a standard distribution board; no overhang issues with a 90 mm height.
Panel integration
Snap-on DIN rail mounting (: any position). The 2 MW width (36 mm) means it takes up two 18 mm slots in a distribution board. The sealable design lets you lock the toggle position with a lead seal or a small padlock, which is useful for utility metering or circuits that must not be switched off accidentally. Supplementary devices like shunt trips, auxiliary contacts, or alarm switches can be clipped onto the side without increasing the width — that's a SENTRON feature that saves panel space if you need remote tripping or status feedback.
