Magnetic Starters

Class 8502 and Class 8702 Type S magnetic contactors are used to switch heating loads, capacitors, transformers, and electric motors where overload protection is separately provided. Type S contactors are available in NEMA Sizes 00-7 and are designed for operation at 600 Volts maximum.

Features and benefits

• A normally open holding circuit contact for three wire control is provided as standard.
• Sizes 00-2 contactors use a Class 9999 SX11 auxiliary contact as the holding circuit contact.
• Sizes 3-7 contactors use a Class 9999 SX6 auxiliary contact as the holding circuit contact.
• Class 8536 Type S Sizes 00-6 starters are provided with a melting alloy thermal overload relay as standard.
• Interchangeable thermal units are available in standard trip (Class 20) Sizes 00-6, quick trip (Class 10) Sizes 00-4, and slow trip (Class 30) Sizes 00-3.
• Single-phase starters use one thermal unit; 3-phase starters use three thermal units.
• Class 8536 Size 7 starters are provided with solid state MOTOR LOGICTM which features:
  • Selectable trip Class10/20
  • Ground fault detection and Communication capabilities for future enhancement
  • Ambient insensitive and features phase loss, phase unbalance and over-current protection.
• Solid state overload relays are available for Sizes 00 – 7 starters. These ambient insensitive overload relays provide phase loss protection, phase unbalance protection and a LED power indicator for quick detection.
• Bimetallic overload relays are also available for Sizes 0-6. Ambient Compensated and Noncompensated versions are supplied with manual and automatic reset, trip current adjustment, and an alarm contact on Sizes 0-2.
• Class 8536 magnetic starters are available in a wide variety of the following enclosures.
  • NEMA Type 1 General Purpose Enclosure
  • NEMA Type 3R Rainproof, Sleet Resistant for Outdoor Use
  • NEMA Type 4 & 4X Watertight and Dust tight
  • NEMA Type 4X Watertight, Dust tight, and Corrosion Resistant Glass – Polyester
  • NEMA Type 7 & 9 Bolted and Spin-Top for Hazardous Locations
  • NEMA Type 9 Bolted for Hazardous Locations
  • NEMA Type 12 Dust tight and Drip tight for Industrial Use
• AC coils are available for application on 50-60 Hertz.
• 600Vac and 810A continuous current rated maximum
• NEMA Sizes 00-4 are supplied with coils that are designed to operate satisfactorily on line voltages of 85% – 110% of rated voltage
• NEMA Sizes 5, 6 and 7 contactors are supplied with a DC coil operated by a solid state rectifier circuit that is powered by an AC source.
  For flexibility field-installable or factory modified accessories include auxiliary contacts, power poles, pneumatic timer attachments, and cover mounted control stations
