Superior Impact Strength The high-impact strength polycarbonate material used in the manufacture of the 56 Series has a proven superior impact strength 56 Series is proven and tested to operate in extreme temperatures from-40 to 55+ High Level of Switch Performance It is important to be aware that there are major differences in standard specifications used to specify switch motor ratings. Most of PDL’s 56 Series switches carry AC23A and AC3 motor ratings to EN60947 and are capable of making up to 8 times and breaking up to 10 times their rated current, which makes them suitable for DOL switching of motors. A motor kilowatt rating is also given for each switch size. Switches carrying an ‘M’ rating only have to pass a few operations at the M current stated, which is to prove an equivalent to "locked rotor", not motor switching. Specially-formulated Chemical Resistance For those environments where harsh chemicals are used such as abatoirs, dairy and food processing indus
