For over a decade specifiers around the world have been using Furse ESP 240/415 M1 protectors from ABB, to safeguard mains power supplies. Further innovations enhance the protection levels.

ABB continues to develop the Furse surge protection device range to ensure the best possible protection of people and equipment. The ESP M1 Series units, which are renowned in the market for quality and innovation, have now been upgraded to provide the latest transient overvoltage protection technology, delivering industry leading voltage protection levels.

As the mains supply current doesn’t pass through the ESP M1 devices, each one is suitable for supplies of 20, 200 or 2000 A. The ESP 415 M1 can be used to protect electronic equipment on three phase mains power supplies (346 – 484 Volts RMS), whilst the ESP 240 M1 is designed to protect electronic equipment on single mains power supplies (200 – 280 Volts RMS).

Electronic equipment protected by the ESP M1 Series range from computers, transmitter/receiver systems and uninterruptible power supplies (UPSs) through to drives and inverters, programmable logic controllers (PLCs) and critical medical equipment.

“The ABB Furse technical design team has taken another step forward in innovation to enhance the ESP 240/415 M1. The ESP240/415 M1 are one of the most advanced surge protectors in the market

today.” said Samad Khan, ABB Furse Global Product Manager – Surge Protection. Samad continues,

“The M1 Series now provides customers, users and specifiers with all of the existing benefits of the original ESP M1 Series, with the addition of the latest, most innovative technology in transient overvoltage protection applied.”

Now the new advanced ESP 240/415 M1 Series offers transient discriminative technology to ensure the industry’s best voltage protection level, safer disconnection from faulty supplies when tested to the latest IEC/EN 61643 standards, plus increased direct surge current (10/350 waveform) ratings (phase and neutral modes to earth).
