MCB reset advice please. Memera 2000 Consumer unit. MCB only, not RCD version. Popped bulb in table lamp has caused power loss to plug sockets in house. Only 1 double plug socket is working as that must be operating on the same circuit as powered by cooker single plug socket (Cooker MCB). MCB marked sockets is showing green light indicating power off yet same MCB switch is in the UP and on position. Wondering why the MCB switch is not in the Off position if it has tripped.

the green is not a light, but a green/red flag showing the position of the internal contacts. Its purpose is to show if contacts are open or closed even if the operating mechanism "switch" is broken
so I suppose yours must be.
time for a new one. Memshield 2 breakers, widely available, will also fit in the Memera 2000 and 2000AD units, they have a greater breaking capacity and are "better." At extra cost you can fit an RCBO which is better still, and valuable in a socket circuit, especially if it supplies sockets that feed outdoor equipment such as lawn mowers or car tools. If you are not competent in this work, look for a qualified electrician who is a member of a self-certification scheme (preferably not on an advertising website like Check a Rated Trader).
Some MEM RCDs have to have the dolly pushed all the way to the "off" position before they can be reset to "on" but I don't believe that applies to the MCBs.
you can post some photos if you want
insert them into your reply with "copy and paste" or the more options "upload a file" button.
MCBs are designed to "trip free", that is the internal mechanism is designed to trip even if the external handle is obstructed.
I would try turning it off and back on again. It's possible that the handle was just a bit sticky and this will free it up.
If you are unable to restore power, but the handle feels consistent all the way through the turn-on movement, then it's probablly a faulty breaker.
If you are unable to restore power and the handle suddenly goes limp during the turn-on procedure, acompanied by a bang that probablly means that you energised against a fault, and the breaker has tripped again. At that point you need someone with appropriate test equipment to find the fault.
