At Techna we specialise in providing premium quality and functioning electrical products for circuit protection, to protect you and your equipment.

Miniature Circuit Breakers (MCBs)

6kA and 10kA Miniature Circuit Breakers (MCBs) for automatically switching off the power supply if the electrical circuit is overloaded and will also provide short circuit protection. Available in 1 to 4 pole and in current ratings from 0.5A to 63A.

Residual Current Circuit Breakers (RCCBs) / Residual Current Devices (RCDs)

6kA and 10kA Residual Current Circuit Breakers (RCCBs), also known as Residual Current Devices (RCDs), for residual current (earth leak / ground fault) protection, come with inbuilt test buttons. Available in 2 or 4 pole and in current ratings from 25A to 125A.

Residual Current Circuit Breakers with Overcurrent Protection (RCBOs)

6kA and 10kA Residual Current Circuit Breakers with Overcurrent Protection (RCBOs) combine the functionality of a RCCB and MCB in one device, protecting against residual current (earth leakage) faults as well as overcurrent and short circuit protection. Available in 2 or 4 pole and in current ratings from 6A to 40A.

Main Switch Isolators

Main Switch Isolators for disconnecting the mains power to an electrical circuit to allow for safe maintenance work to be carried out. Available in 100A or 125A and in 1 to 4 pole.

Thermal Circuit Breakers

‘Push to Reset’ single pole Thermal Circuit Breakers provide thermal overload and short circuit protection. Small and compact in size and available in current ratings from 0.5A to 45A.

Busbars and Pan Assemblies

Busbars in both pin and comb/fork styles for connecting a row of MCBs from a single incoming cable and three phase Pan Assemblies to assist with time saving installation, available in 4 to 24 triple pole ways and rated at 250A.

Air Circuit Breakers (ACBs)

Air Circuit Breakers provide protection and switching for electrical equipment from 630A to 6300A. Available in three different sizes, in 3 or 4 pole and as a fixed or withdrawable design.
