Typically 10kA MCBs range from 6A through to 63A, which caters for most applications, but wouldn’t it be useful to have the ability to use an 80A MCB when it’s necessary? Wouldn’t it be great if that solution was available as an 18mm DIN mounted 80A MCB that can be fitted into standard MCB distribution boards?
Fortunately Siemens have introduced such an item, the 80A 5SY4 MCB which matches the 5SL4 profile and can be used alongside the 5SL4 devices in standard Alpha BSII 250A TP&N distribution boards. So, when the need arises your job will be much easier with Siemens Alpha circuit protection products. Earth Leakage Breaker
Alpha BSII distribution boards are designed, tested & manufactured in the UK and are fully compliant with BSEN 61439-3 and can make compliance with Amendment 2 of the Wiring Regulations easier too with an easy fit AFDD solution and integral SPD facility.
For 176 years, Siemens has turned great inventions into innovative technologies and risen to the challenges of a demanding world. Only three years after the company was founded, a sales office was opened in England, and in 1858, the London office was converted into an independent company headed by William Siemens. Nowadays there are numerous Siemens sites in the UK, one of which manufactures the Alpha low voltage distribution products.
