Motor Control Contactor
1. Combination Contactor
NEMA combination contactors are available in disconnectors or circuit breakers for installation on general purpose equipment. Our products also have a variety of enclosures to suit the needs of various applications.
2. IEC contactor
Our IEC contactors provide AC and DC control. They are environmentally friendly, versatile and flexible. These contactors protect your other equipment while delivering the performance you expect.
Large Contactors: Our Bulletin 100-E are available in a variety of sizes from 116 - 2650 A, helping to reduce width and weight, saving panel space. Its universal electronic AC/DC coils make selection easier, provide significant energy savings, and can be directly connected to a PLC.
Standard Contactors: Our Bulletin 100-C offers 9 - 97 A contactors in a space saving and high performance design. These low-power contactors can be used to control motors and other loads.
Small Contactors: Our Bulletin 100-K IEC Small Contactors are suitable for commercial and light industrial applications where panel space is at a premium. With a width of 45mm, these small devices are thinner and require less panel depth than standard IEC contactors. Bulletin 100-K Miniature Contactors are the replacement product line for the Bulletin 100-M Contactor Series.
Safety Contactors: Our Bulletin 100S/104S IEC Safety Contactors provide mechanically connected or mirrored contact performance up to 750 A to meet the needs of feedback circuits for modern safety applications. Our Bulletin 100S Safety Contactors use mirrored contact performance to safely isolate hazardous moving loads. The mirrored contacts provide a reliable indication of the open or closed state of the mains electrodes.
Capacitive Switching Contactors: Our Bulletin 100Q Capacitor Switching Contactors are designed for switching capacitor banks. Front mounted resistor elements limit excessive inrush current. This reduces stress on the contactors and capacitors. Our contactors are compact and economical without the use of air-core reactors.
3. NEMA Contactor
We offer NEMA 00…9 motor rated contactors in open and closed designs for full voltage starting of AC motors. Our contactors can also be used for non-motor and lighting loads. We also offer a variety of NEMA contactors with marine approvals for many marine and offshore applications. We offer feed isolated lighting contactors for switching large light blocks on and off.
AC Contactors: Our Bulletin 300 NEMA contactors and motor starters provide a space-saving and cost-effective alternative for applications requiring NEMA compliant motor control. These NEMA compliant products are based on our Bulletin 100 IEC contactor design and are compatible with a wide range of accessories as well as solid state overload relays.
Stationary Contactors: Bulletin 400 Stationary Contactors are small in size to save space while still delivering high performance. This line of contactors meets or exceeds electrical and mechanical requirements for stationary components.
Motor Load Feedthrough Wiring Contactors: Bulletin 500F AC Contactors (Open Type) are available in NEMA size 0…5 feedthrough wiring configurations. The busbar terminals are on the top of the element and the load terminals are on the bottom. These contactors can be used to switch AC motor loads that do not require or alone provide overload protection. Our contactors can be operated remotely using indicating devices such as pushbuttons, selector switches, timers, relays or thermostat switches.
Motor Load Top Wire Contactors: Bulletin 500 AC contactors feature top wire construction, NEMA sizes 00 through 9. All power connectors are located on top of the contactor. If overload protection is not required or provided separately, use our contactors to switch AC motor loads. These contactors can be operated remotely using a pointing device such as a button, selector switch, timer, relay or thermostat.
Vacuum Contactors: Our Bulletin 1102C/1104C and Bulletin 1502 NEMA Medium Voltage Vacuum Contactors maintain motor control system reliability in harsh and dirty environments. Our compact contactors are long lasting and vacuum technology enables extremely efficient arc quenching above 600V. These vacuum contactors are mechanically and electrically interlocked to avoid simultaneous closing of the contactors.
4. 156-C Solid State Contactor
Our Bulletin 156-C Solid State Contactors complement the Bulletin 700 Solid State Relay family to provide you with a complete solid state solution offering. Our contactor designs contain no moving parts or contacts that could wear out. This feature reduces or even eliminates costs associated with maintenance, parts replacement and downtime.
