Eaton B3NO-2 – Frequently Asked Questions

1) What does the Eaton B3NO overload relay alarm kit actually do on a motor starter?
It is an add-on accessory that gives an A200 series NEMA contactor or starter overload alarm signaling. The relay still trips the motor circuit on overload; the kit provides the contact that lets you annunciate that trip back to a panel light, PLC input, or BMS point instead of finding out when someone reports the motor is down. It mounts alongside the existing contactor or starter hardware.
2) Will the B3NO alarm kit fit Eaton A200 series starters, or does it work on other contactor lines too?
This alarm kit is built specifically for Eaton A200 series NEMA contactors and starters. It is not a universal accessory, so if your panel uses a different Eaton line or another manufacturer's starter, this is the wrong part. Check the catalog number on the starter itself, not the enclosure label, before you order.
3) What is the difference between the B3NO-2 and B3NO-4 alarm kits?
Both are the same Eaton alarm kit for A200 series starters; the part number suffix is the configuration option, 2 or 4. Order B3NO-2 or B3NO-4 to match the configuration your starter assembly calls for. They are separate catalog numbers, so specify the suffix on the order, not just B3NO.
4) Can I add overload alarm signaling to an existing A200 starter already in service, or do I need a new starter?
You can retrofit. The B3NO is sold as a field accessory for A200 series contactors and starters, so an installed starter can be upgraded with alarm signaling rather than replaced. De-energize and lock out the bucket first, then fit the kit to the existing overload assembly.
5) Is the Eaton B3NO alarm kit certified for Canadian installations?
Yes, the kit is CSA Certified, which is the listing most Canadian AHJs and industrial spec writers look for on motor control accessories. That certification is the only one carried on this kit.
