The primary function for a Miniature Circuit Breaker (MCB) is to first detect a fault condition, this is usually done within the device itself. Once a fault is detected, the copper (or other highly conductive material) contacts within the MCB open in order to interrupt the circuit, this is generally done by using mechanically stored energy contained within the breaker.
Mains Switches (MSWs) are usually used between the incoming power that comes through the electric smart meter to the Distribution Board in the commercial or industrial site. Rated at 100A to 125A and most commonly supplied with either 2 poles for single phase live and neutral or 4 poles for 3 phase and neutral.
An RCCB (residual current circuit breaker) provides protection against residual current faults, most commonly referred to as earth leaks or (in the USA) ground faults. However, RCCBs can also be used to protect three phase systems where the fault may be to earth but could also be between live phases.
An RCBO offers the capabilities of both an MCB and RCCB in a single package. The RCBO thus becomes a circuit protection device combining earth leakage (ground fault) protection with overload and short circuit protection, to disconnect the incoming power from the connected device(s) in the event of a fault.
Isolator Switches are supplied with a hand lever or pushbuttons in a sealed box. They can be mounted outside the building open or in a key locked box or inside at an exit door. Load break switches are used as the main disconnect for industrial control panels and usually feature a door interlock feature.

Quite possibly the rudest people i have had the displeasure of speaking too. When asking for advice they simply do not know what they are talking about. i then had the "lovely" accounts lady (channel or something) chasing me for an invoice that was a few days overdue. She spoke to one of my staff and was so rude it was unreal! i certainly would not have my accounts talking to my customers in this way. needless to say i wont be placing any further orders with this company!!! AVOID

A company that actually seemed to go out of their way to be rude to you.
Including turning their backs to you to look out the window mid conversation, asking very unnecessary questions about your personal life that have nothing to do with the subject discussed and answering every query with "Look on our website". All whilst looking at you as if you are something they have scrapped off their shoe.
Just a misery to deal with, I actually saw one of the managers urinating into a bush as I approached the offices which was absolutely disgusting.
