Product Features

Product Overview

Sizes available 00, 0, 1, 2, 3, 4, 5, 6, 7 in 120v or 220v coils. Open style or NEMA 1 enclosures. Adjustable overloads. Class 30. Available with HOA’s & Start-Stop switches.

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.
