Particle ingress i.e. dust/industry by-products?

Overcurrent trip - type fitted ie:oil-filled dashpot ?

Ambient temperature and humidity?

Number of major faults-events and severity ?

Loading profile ? i.e. constant,cyclic, close to Max ?

Other benefits

With modern compact modular ACBs the protection zones can be extended to include.REF, UREF or remote monitoring & control.
