• Double break contact design

• Captive terminal screws

• Touch-safe design: all connection
terminals are protected against accidental
touch

• Terminals supplied open for ease of
wiring

• Operates over an extended voltage range
of 85% to 100% of rated control voltage

• N.C. dynamic braking pole is easily
added to two pole contactors

• Screwdriver guide holes

• Snap-on front mounted accessories

• UL and CSA approved

Type EHDB

• 75 amps to 960 amps in ten sizes

• 2 pole (2 N.O.) and
3 pole (2 N.O. & 1 N.C.)
power poles available

• 600 VDC making capacity:
300 VDC breaking capacity

• Auxiliary contacts suitable for low
energy applications are standard
(17V, 5mA)

• 1 N.O. & 1 N.C. auxiliary contacts are
standard and up to six additional
auxiliary contacts may be added to
provide a total of 8 (4 N.O. & 4 N.C.)

• Early make & late break auxiliary
contacts available

• Auxiliary contacts available to meet
EN 81 standards

• EHDB 220, 280 & 360 contactors have
withdrawable coils

• Mechanically interlocked contactors
available for reversing applications

Description

EHDB drive contactors are specifically designed for use with solid
state D.C. adjustable speed drive systems. In drive applications, the
contactor is not required to make or break the load during normal
operation. The N.C. contact is used for dynamic braking applications.

Coil voltage selection

All catalog numbers include a 120V coil. To select other coil voltages,
substitute the code from the coil voltage selection chart for the first
digit after the dash in the catalog number.

DC operated contactors

EHDB130 – EHDB960
DC and AC operated contactors have the same magnet structure

except the DC coil includes a resistor and a normally closed late break
auxiliary interlock. To order, substitute the code from the coil voltage
selection chart and refer to the DC magnet coils chart for the price
adder.

DC operated contactors are supplied with 2 N.O. & 1 N.C. auxiliary
contacts. One additional 1 N.O. & 1 N.C. auxiliary contact block can be
mounted on the left side of the contactor.
