Wire CONTROL relay coil in CONTROL circuit on secondary side of CONTROL transformer. b. Wire two poles of CONTROL relay in series with contactor coil at line positionDevices must be mounted to a sturdy vertical surface with the line side terminals up. No other orientations are temperatureEquipment is designed for ambient temperature outside of equipment enclosures to be -25 to 40 C. When contactor is energized, temperatures will be above outside ambient in equipment enclosures.

5 Temperature rises inside the enclosures should be limited so that internal air temperature does not exceed 65 C for sizes 00 to 6 and 60 C for sizes 7 to 9. If condensing moisture is present, space heater kits should be used to prevent condensation when contactor is not temperature should be -30 to 65 C. If equipment is stored over 1 week, it may be necessary to cover the equipment and provide a source of heat to prevent full voltage power devices , CONTROL SECTION 11-5 Short-circuit ratingsFusible forms of combination magnetic starters equipped with UL labeled, nonrenewable, NEC-type fuses listed in the table below, are adequate for installation on motor branch circuits where the available short-circuit current at the incoming line terminals of the starter does not exceed the value breaker-type combination magnetic starters equipped with the circuit breakers listed in the table at right are adequate for installation on motor branch circuits where the available short-circuit current at the incoming line terminals of the starter does not exceed the value either type.

8 It is on standard specifications of major manufacturers. The line offers features and benefits most asked for by available include reversing and nonreversing, two-speed, and combination, sizes 00 9. Toolless contactor disassembly (sizes 00 4) allows quick access for inspection and maintenance. Just release two retainers and pull a clip to get at magnet, coil, and contacts. Saddle clamp terminals (sizes 00 1) accommodate ring, spade, and stripped wire leads and carry permanent stamped-in identification. Staggered arrangement makes wiring easier and helps prevent shorting between phases. Current-carrying components contact tips are weld-resistant silver cadmium oxide (fine silver on sizes 00 and 0 only). Contacts are installed in a wedge configuration for positive make with minimum bounce. Optional PF capacitor terminals permit easy connection of power factor correction capacitors between contactor and overload relay for energy conservation.

9 Class 20 overload protection. Visual trip indicator with manual reset to avoid surprise restarts. Reset occurs on arm upstroke so a tripped condition can t be overridden by holding the arm down. Manual weld check provides a convenient test against welding of overload relay contacts. Just depress the weld check operator to trip the relay, run a simple continuity test across the relay contacts, then depress the manual reset to return the starter to service. Optional isolated NO contact on the overload relay provides means of direct interface with programmable controller or computer to monitor performance and diagnose faults. Dual bimetals anticipate overloads, responding to rising current and temperature with faster tripping on severe overloads for better motor protection. Trip points are factory-calibrated for accuracy. 10% trip adjustment by turning a dial in the overload relay face allows tuning the protection to the motor on the spot.
