300-line overload relays

Broad selection for positive motor protection

The 300-line three-leg block overload relay includes features that provide positive motor

protection and added operator safety.

Dual bimetallic overload: The dual bimetallic overload relay anticipates motor overload,

responding to rising current and temperature with faster tripping on severe overloads for

better motor protection.

Isolated NO contact: Where it’s essential to monitor performance or diagnose faults, a 300-line starter

may be ordered with an additional isolated,  high fidelity, normally open contact in the overload relay.

This contact may be used for direct input to a programmable controller or interface with a computer.

Manual weld check: The overload relay can be manually tripped as a convenient way to check

against contact welding. Depressing the manual weld check arm trips the relay. A welded contact

can then be detected with a simple continuity check across the relay contact terminals.

Visual trip indicator: Unsafe overriding the reset arm is eliminated because overload reset occurs only

when the reset is released. A bright yellow visual trip indicator tells you at a glance if the relay has

tripped. An optional automatic reset overload relay is available for special applications upon request.

Interchangeable heaters: Overload relay heaters are completely interchangeable with 200-line starter

heaters, eliminating the need to stock an additional line of heaters.

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!

300-line magnetic motor starter

All these features plus an edge on productivity

The 300-line starter is a full voltage, magnetic motor starter with encapsulated coil and three-leg

block overload relay with visual trip indicator, manual reset and manual weld check.

It incorporates all the features and benefits users demand and has

received standard specification approval by many major manufacturers.

The 300-line is available in the following forms:

NEMA sizes 00–6

• Standard non-reversing

• Reversing

• Two-speed

• Combination

and in a wide selection of enclosures:

• Type 1 general purpose

• Type 3R rainproof, sleet-resistant

• Type 4 watertight, dust-tight

• Type 4X watertight, dust-tight, corrosion-resistant

• Type 12 driptight, dust-tight

Simplicity in design

The right control for your application every time

A wide range of choices

• Non-reversing, reversing, two-speed and combination motor starters in sizes 00–6

• NEMA Type 1. 3R, 12. 4 and 4X enclosures available

• Save time and money with a single source for all your applications

Versatile, durable and the industry’s easiest to maintain

• Change the coil voltage on a contactor or starter to suit your application

• Inspect and change out contacts without removing any wires, or removing the

starter from the enclosure

Two options for motor protection

• Three-leg block overload relays feature dual bimetal overload protection and

adjustable ±10% trip current for added flexibility

• Solid-state overload relays provide added motor protection for critical processes,

feature selectable 10/20/30 trip class for application flexibility and surface-mount

technology for increased reliability

Largest selection of modification and accessory kits

• Cost-effective solutions

• Allows for application and configuration flexibility

• Kits include auxiliary contacts, coils, surge-suppression, fifth-pole, mechanical  interlocks,

control circuit fusing, NEMA type enclosures, selector switches, indicating lights, control

transformers, space heaters and more

300-line Industry-leading full voltage motor control

The 300-line of NEMA-rated controls offers dependability and long-term  performance for the

most demanding industrial installations. And with all the options available, 

you can match the 300-line to your toughest applications.

Simplicity and durability are key to the 300-line.

The unique design allows for contact inspection or coil change-outs in just seconds, and contact

replacement in a matter of minutes. There’s no need to use tools to remove the starter or

contactor from the enclosure, or to remove control or power wires.
