Please note that due to the current Load Shedding we are experiencing a higher demand than usual and stock or response time may be slightly delayed. We are doing our best to get back to everyone as soon as possible. Please bear with us at this time.

Please note the availability of batteries is very limited and items may need to be placed on back-order. We cannot guarantee stock being available immediately.



20Amp 6kA MCB

MCB's detect over currents due to both overload and fault currents. The MCB will operate and interrupt the supply to prevent damage to the installation. Domestic MCBs have a short circuit breaking capacity of 6000A (M6). The current carrying capacity of the cable should always exceed the current rating of the MCB to prevent damage.
The operating dolly may be locked in either the ON or OFF position without affecting the ability of the trip mechanism to operate. When in the off position, a contact gap of 4 mm is achieved. The multi pole MCB’s are equipped with a strong terminal design which gives a better grip on the cable. The unique design of the terminal compensates and corrects for any distortion or possible loss in terminal torque.

Product Description

Details

A more significant limitation capability of short circuit current:

The limitation capability of a MCB is an internal characteristic which makes it possible to open the circuit before the short circuit current reaches its prospective maximum value.

A MCB with a better current limitation capability provides several advantages:

*to reduce the thermal effects in the cable i.e increase life span of cables
*to reduce the mechanical effects and electrodynamics forces on the different contacts
*to reduce the electromagnetic effects which can be harmful to sensitive equipment / loads.
