ABB 300-line contactor High performance with simplified maintenance

300-line contactor

High performance with simplified maintenance

Several features combine to make the 300-line contactor a high-performance unit

that is easy to inspect and maintain.

• All line and load terminals on NEMA size 00. 0 and 1 starters can accommodate ring, spade

and stripped-wire terminations

• Tool-less disassembly for sizes 00–4

• Terminal numbering is permanently stamped

• NEMA size 00–1 terminals are staggered for easy termination

• In-line, stripped-wire connections are standard for NEMA size 2–6 starters

• Ring terminal options available for sizes 2–5

• Optional terminals available on NEMA size 1–4 starters to permit easy connection of power

factor correction capacitors for energy conservation

• NEMA size 1 starters and larger feature weld-resistant silver alloy contact tips

• Contacts have a wedge-shaped configuration for positive make with minimum bounce

• Size 00. 0 and 1 contacts can be easily changed from normally open to normally closed without

additional parts

• The magnet provides long life and is specially treated to resist rust

• Molded coil is impervious to moisture, dirt and oil and is highly resistant to mechanical damage and

high-humidity failure

• Retaining clips engage detents encapsulated in the coil to hold it securely in place

The 300-line contactor provides easy disassembly in sizes 00–6:

• Lift off the armature to allow quick inspection and ready access to contacts

• Pull the spring clip from the armature to access the coil

• No need to remove any wiring!
