We now offer PRIMARY INJECTION TESTING (capable of producing up to 6000A RMS), suitable for testing MCCB’s/Overloads up to 2500A.

PRIMARY TESTING – performs real life current flow through the device, as opposed to SECONDARY TESTING which is only a simulation.

PRIMARY TESTING – will highlight other problems, such as High Contact Resistance.
Older MCCB’s/ACB’s CAN ONLY BE TESTED BY THIS METHOD – As they have THERMAL/MAGNETIC elements, not ELECTRONS.

Pre-empt Problems – Primary Injection Testing Saves Time and Money
