Eaton B100S0C – Frequently Asked Questions

1) Does the Eaton B100S0C motor starter come with overload heaters?
No. The B100S0C ships without heaters, so the overload heater elements have to be ordered separately and sized to the motor's full load current before the starter is complete. Budget that as a second line item on the order, not an accessory you can skip.
2) What coil voltage is the Eaton Type B100 NEMA Size 0 starter?
The coil is rated 208V, so your control circuit has to supply 208 volts to pull the contactor in. If the panel's control transformer puts out 120V or 240V, this starter is the wrong coil and you need a different coil voltage version.
3) What size motor will a NEMA Size 0 B100 starter with a 1-5A overload handle?
The overload range on this one is 1 to 5 amps, so it suits small polyphase motors whose full load current falls inside that window. If your motor nameplate FLA is above 5 amps, this overload range won't protect it and you need a higher range or a larger NEMA size.
4) Can the Eaton B100 starter run a motor in both directions?
No. It is a Type B100 non-reversing starter, single direction only. Reversing a three phase motor requires two interlocked contactors, so for forward and reverse duty you need a reversing starter instead of this one.
5) Will this Eaton starter fit inside my existing control panel?
Its footprint is 1.77 in wide, 5.5 in deep and 6.3 in high, which is narrow enough to sit alongside other devices on a panel back plate. Lay out 6.3 inches of vertical clearance plus wiring gutter space when you plan the enclosure.
6) Is the Eaton B100 Size 0 starter single phase or three phase?
Three-pole, intended for polyphase motors, so it switches all three legs of a three phase feed. A single phase motor only needs two poles switched, so while the device is oversized for that job the three-pole B100 is built around three phase motor control.
7) Is the Eaton B100S0C starter approved for use in Canada?
It carries CSA Certification, which is the listing Canadian inspectors look for on motor control equipment. That makes it acceptable for Canadian commercial and industrial panel work.
8) What exactly do I order to get this Eaton starter, and what part number is it?
The starter itself is Eaton part number B100S0C: a NEMA Size 0, three-pole, non-reversing starter with a 208V coil and 1-5A overload range. Add the correct heater elements as a separate line, chosen from the motor's nameplate full load amps.
