IS : 13947 (PT-4/SEC-1) CM/L 7391076   DOL Motor Starters Difference between Type PK1 and Type PC DOL Starter Type PK1 Starter is ISI marked as a whole starter and also the contactors and thermal overload relay used in the starter are individually ISI marked In case of Type PC starters, only the contactors and thermal overload relay are individually ISI mark and not the whole starter unlike Type PK1. These starters cover motor rating up to 7.5Hp These starters cover wide range of motor rating from 10Hp to 75Hp.   Salient Features common to Type PK1 and Type PC DOL Starters TYPE PK1 TYPE PC Fully conforms to IS: 13947(Part 4/Section1) and other standard equivalent is IEC 60947-4-1/60947-1/60947-4-2. These starters consist of a Type PK1 contactor and a Type PC/PNR Thermal Overload Relay each bearing an ISI mark. These Starters are suitable for category AC-3 duty Most reliable motor protection widely accepted in Industrial as well as Agricultural sector. Elegant in appearance and design. Guaranteed performance is assured due to world-class design and quality manufacturing of the starters. Contactors and relays are manufactured to withstand high ambient temperature, humidity and under voltage conditions. Exceptionally long contact life of Air Break Contactor used in Motor Starter due to silver alloy contact tips and bounce free contacts. Suitable for copper as well as aluminum conductors as per Indian Standards. The sheet steel enclosure is robust and powder coated to withstand adverse climatic condition. Degree of Protection: IP 42 It also acts under voltage release and protects motor from the effects of low voltage operations. OFF Push button can be latched in OFF position to prevent accidental switch ON. Wide range of Thermal Overload Relays, which can operate within temperature range of –5º C to 50º C ambient. Exceptionally low temperature rise.
