Ingersoll Rand – T30

A leader in its class since 1929

The Ingersoll Rand T30 has been the leader in its class since it was introduced

in 1929. Whether this is measured by reliability, efficiency, rugged flexibility

or maintainability, it has no equal. Designed for heavy industrial applications,

the two stage reciprocating air compressors provide the quality and

performance that exceed customer requirements.

Others may claim to handle heavy duty applications, but the T30 defines

the concept. Run it in the most demanding intermediate duty application

imaginable. The T30 unique and ideal to meet your demands of a compressor

package in the 3-30 HP range.

A two-stage model (1) compresses air to an intermediate pressure in the first stage,

(2) removes heat of compression through an intercooler, and (3) compresses air

to a final pressure in a second compression stage. Two-stage compressors are more

efficient and are generally used for pressures above 100 PSI (maximum pressure to 175 PSI).

For low voltage applications

• High fidelity auxiliary contacts for applications where it is necessary to detect starter or

contactor operation with circuits that use low voltage levels, such as programmable

controls or computer systems

• Control amplifier is available for applications with low level 24 V DC outputs to operate 300-line

contactor and starter control coils at line voltag Coil kits adapt for different voltages

• Encapsulated coils in kit form enable you to change contactor coils for different voltages

• Coils are rated up to 600 volts, 50 and 60 hertz

• Coil changes are quick and easy

Surge suppression kits provide protection and are designed to meet the demands of

solid-state circuitry

• Prevent undesirable reactions in logic circuits by using an RC network to absorb energy surges

from opening the coil circuit

• Eliminate the need to install a separate resistor and capacitor network

• Easy to install and requires only one wire connection — the mounting plate makes the other

electrical connection

• Unit installs neatly on the contactor coilretaining clip

Accessories

Meet your special operating needs

ABB offers a large selection of accessories that allow you to extend the application

of your 300-line starters to match your operating needs.

Auxiliary contact kits deliver added versatility to magnetic starters

• Provide additional control circuits to energize accessory equipment, such as indicating lights

or to control sequencing of other motor starters

• Can be added to all across-the-line magnetic starters, reversing controllers and two-speed

controllers

• Each auxiliary contact rated at 10 amperes AC,continuous current (NEMA A600), and is suitable

for right or left side mounting

• Kits include either a basic contact block or an adder block supplied with a single or double circuit

Mechanical interlock kits

• Used when reversing or multi-speed controllers are customer assembled — usually for panel

mounting

• Mechanically interlocks two contactors or starters so that one does not pick up until the other has

dropped out

Contact kits for simple and fast replacement

• Complete set of kits for contact replacement due to normal wear

• Designed for quick and easy replacement in just minutes, without removing wires or removing the

starter from the enclosure

• Kits include all necessary replacement components

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

protection and added operator safety.

±10% adjustment: Relay trip points are factory calibrated for high accuracy. For added flexibility,

the trip current of the relay is adjustable ±10% to allow tuning the protection to any given motor

current and to eliminate nuisance tripping. A single calibration adjusts all three legs. The overload

relay is available in standard or ambient- compensated forms.

The CR324X solid-state overload relay provides added motor protection in critical

production processes where uptime is vital. It mounts directly to 300-line starters, and a

panel-mount version is also available for added application flexibility. Its advanced features can

save you time and money:

• Heaters are eliminated

• Phase loss protection prolongs motor life under adverse conditions

• Solid-state surface-mount technology increases reliability, offers excellent vibration resistance

and reduces heat generation

• Selectable 10/20/30 trip class offers flexibility for a range of applications

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.
