Overview of Allen‑Bradley Bulletin 100 IEC contactors, covering features, ratings, accessories, certifications and energy‑saving coil technology.
The Allen‑Bradley Bulletin 100 series offers a full portfolio of IEC contactors ranging from 5 A miniature units to 2650 A large‑frame devices. All models share a universal electronic AC/DC coil that reduces power consumption and allows direct PLC connection without extra relays.
The contactors include built‑in surge suppression, optional PLC interfaces, and a wide range of accessories such as auxiliary contacts, reversing kits, and interlocks. They meet IEC, UL, CSA, CE and cULus certifications and are RoHS compliant, making them suitable for commercial and light‑industrial applications where panel space and energy efficiency are critical.
| Current rating range | 5 A to 2650 A |
|---|---|
| Coil voltage (example model 100‑E) | 24 V DC |
| Hold‑in current (universal coil) | 10 mA at 24 V DC |
| Drop‑out time (100‑E) | 18‑23 ms |
| Width of miniature units | 45 mm |
The universal coil requires a low hold‑in current of 10 mA at 24 V DC.
They are CE marked and cULus listed, with additional certifications such as CCC and SUVA for safety models.
The miniature devices are 45 mm wide, saving panel space compared with standard IEC contactors.
