I have an old, very old 2 contactor Star/Delta starter an Auto Memota 254SD started to be precise.....
I'm just enquiring if this starter still complies with any relevant British standards
I started my electrical journey in 1967, this starter predates this time by about 30 years!
All my experience of S/D starters since I started out has been on 3 contactor types. It's starting a similar aged 10hp Crompton Parkinson induction motor.
Quite interesting watching the run contactor kicking in when changing over from Star to Delta there are arc shields over the contacts, I understand why now.
Any help from any greybeards much appreciated.
