General Information
The D-line contactors and overload relays are the largest selling line of contactors and starters in the
world. They offer high reliability with long mechanical and electrical life and the most complete line of
accessories in the industry.
Contactor Ratings
• D-line contactors and overload relays are available in 11 contactor ratings for the USA market for
• 3-pole and 4-pole contactor versions available.
• All contactors include built-in auxiliary contacts.
• All screw connections have IP20 rated touch-safe terminals with both North American and
• D-line contactors can be panel mounted with screws or DIN rail mounted.
Easily Installed Accessories
• Auxiliary contact blocks with serrated wiping action
• Front mount dust tight auxiliary contact blocks
• Pneumatic time delay blocks
• Transient voltage surge suppressors
• Interface modules and electronic timers
• Mechanical latching blocks
Control Circuit Flexibility
The D-line contactors are available with ac or dc operating coils. Several devices utilize a low-
consumption dc coil with built-in transient suppression for operation with a low-level dc signal from a
computer or PLC without need for an interposing relay.
Overload Relays
Class 10 or Class 20 bimetallic overload relays are available up to 140 A. They are bimetallic ambient
compensated and are available with or without single-phase sensitivity for phase unbalance and phase
loss protection. New solid state overload relays are available for 90 to 150 A applications. Both bimetallic
and solid-state overload relays include the following features:
• Isolated N.C. trip contact and N.O. alarm contacts.
• Manual or Automatic reset function (bi-metallic versions only).
• Tamper-resistant window for FLA settings.
• Test trip button.
inductive motor applications up to 150 full-load amps and resistive loads up to 200 A. They offer
motor control and overload protection for motors rated up to 100 hp at 480 Vac or 125 hp at 600 Vac.
