Product Description:

Non-Reversing

Three-phase, full voltage magnetic starters are most commonly used to switch AC motor loads. Starters consist of a magnetically actuated switch (contactor) and an overload relay assembled together.

Reversing

Three-phase, full voltage magnetic starters are used primarily for reversing of three-phase squirrel cage motors. They consist of two contactors and a single overload relay assembled together. The contactors are mechanically and electrically interlocked to prevent line shorts and energization of both contactors simultaneously.

Features, Benefits and Functions;

• Bimetallic ambient compensated overload relays—available in three basic sizes covering applications up to 900 hp— reducing number of different contactor/overload relay combinations that have to be stocked

These overload relays feature:

• Selectable manual or automatic reset operation
• Interchangeable heater packs adjustable ±24% to match motor FLA and calibrated for 1.0 and 1.15 service factors. Heater packs for smaller overload relay will mount in larger overload relay— useful in derating applications such as jogging
• Load lugs built into relay base
• Single-phase protection, Class 20 or Class 10 trip time
• Overload trip indication
• Electrically isolated NO-NC contacts (pull RESET button to test)
• The C440 is a selfpowered, robust electronic overload designed for integrated use with Freedom NEMA contactors
• Tiered feature set to provide coverage specific to your application
• Broad 5: 1 FLA range for maximum flexibility
• Coverage from 0.05–1500A to meet all your needs
• Long life twin break, silver cadmium oxide contacts—provide excellent conductivity and superior resistance to welding and arc erosion. Generously sized for low resistance and cool operation
• Designed to 3,000,000 electrical operations at maximum hp ratings up through 25 hp at 600V
• Steel mounting plate standard on all open type starters
• Wired for separate or common control Non-Reversing
• Holding circuit contact(s) supplied as standard
• Sizes 00–3 have a NO auxiliary contact block mounted on right-hand side (on Size 00, contact occupies 4th power pole position—no increase in width)
• Sizes 4–5 have a NO contact block mounted on left side
• Sizes 6–7 have a 2NO/2NC contact block on top left
• Size 8 has a NO/NC contact block on top left back and a NO on top right back

Reversing

• Each contactor (Size 00–8) supplied with one NO-NC side mounted contact block as standard. NC contacts are wired as electrical interlocks

Magnet Coils—AC or DC

Contactor coils listed in this section also have a 50 Hz rating as shown in the Coil Voltage Code section. Select required contactor by Part number and replace the magnet coil alpha designation in the part number (A) with the proper Coil Voltage Code.

For Sizes 00–2, the magnet coil alpha designation will be the next to the last digit of the listed Part number. EXAMPLE: For a 380V, 50 Hz coil, change CN15AN3_B to CN15AN3LB. For all other sizes, the magnet coil alpha designation will be the last digit of the listed Part number.

(1) Starter Part numbers do not include heater packs. Select one carton of three heater packs. Heater pack selection

(2) Maximum horsepower rating of starters for 380V 50 Hz applications:

(3) GOLD TEXT (A) indicates coil suffix required, Insert correct coil suffix for your needs, see AC Suffix table.

(4 )The service-limit current ratings represent the maximum rms current, in amperes, which the controller shall be permitted to carry for protracted periods in normal service. At service-limit current ratings, temperature rises shall be permitted to exceed those obtained by testing the controller at its continuous current rating. The current rating of overload relays or trip current of other motor protective devices used shall not exceed the service-limit current rating of the controller.

(5) Common control. For separate 120V control, insert letter D in 7th position of listed Part number. Example: AN56VND0CB.

(6) NEMA Sizes 00 and 0 only.

(7) NEMA Sizes 00 and 0 only. Sizes 1–8 are 24/60 only.

Prices of starters do not include heater packs.
Select two packs (two overload relays, one for each speed). Heater Pack Selection.

(1) If branch circuit protective device is 45A or greater, C320FBR1 fuse kit(s) may be required for circuit protection per NEC 530-072.
(2) NEMA Sizes 00 and 0 only. Sizes 1–5 are 24/60 only.

Heater Pack Selection

Heater packs H2001B to H2017B and H2101B to H2117B are to be used only with Series B overload relays Part Numbers C306DN3B (Part No. 10-7016) and C306GN3B (Part No. 10-7020). The load lugs are built into the overload relay base to allow load wiring prior to heater pack installation. The previous heater design had integral load lugs. The Series B heater packs are electrically equivalent to the previous heater design. Heaters H2018-3 to H2024-3 have not changed.

(1) The series of a starter is the last digit of the listed Part number. Example: AN16DN0AB.

Product Description:

Single-phase, full voltage magnetic starters connect the motor directly across the line, allowing it to draw full inrush current during start-up. These starters are most commonly used for control of self-starting single-phase motors up to 15 hp at 230V. They consist of a two-pole electromagnetic contactor to make and break the motor power circuit and an overload relay to provide running overload protection. Starters listed in the table include:

• Two-pole Freedom Series contactor with long life twin break, silver cadmium oxide contacts. Generously sized for low resistance and cool operation. Designed to 3 million electrical operations at maximum hp and 30 million mechanical operations to Size 0, 10 million operations to Size 2 and 6 million operations to Size 3
• Three-pole Freedom Series overload with poles two and three wired in series for motor overload protection. This overload is ambient compensated, selectable manual or automatic reset, interchangeable Class 10 or 20 heater packs, 1.0 or 1.15 service factor selectability, overload trip indication and electrically isolated NO-NC contacts (pull RESET button to test)
• Holding circuit NO auxiliary contact supplied as standard. On Size 00, the contact occupies the 4th power pole position. Sizes 0–3 have the NO auxiliary mounted on the right side of the contactor
• Steel mounting plate as standard on all open type starters. Wired for separate or common control
