Product Features
- Pack of 3 Heater Elements: The H2010B-3 is sold as a set of 3 bimetallic heater elements — sufficient for a complete 3-phase motor starter installation. One element per phase.
- Four Adjustable Dial Positions: A single pack covers four FLA settings (6.75A, 8.17A, 9.58A, 11.0A) via the dial on the overload relay body. Match the dial position to the motor’s nameplate FLA for accurate thermal protection.
- Class 20 Standard Trip: Provides thermal overload protection with a Class 20 trip time characteristic — appropriate for standard motor starting applications including pumps, fans, conveyors, and HVAC compressors.
- Bimetallic Sensing: Uses bimetallic strip technology to detect motor overload conditions through heat generated by excess current, providing reliable and repeatable thermal protection.
- Adjacent Range — H2011B-3: The H2010B-3 covers FLA up to 11.0A. For motors with FLA above 11.0A, the H2011B-3 (9.14–14.0A) is the next heater pack in the range.
- Also Known as Cutler-Hammer H2010B-3: Sold under both the Eaton and Cutler-Hammer brand names. Both refer to the same part.
- UL Listed & CSA Approved: Approved for use in compliant motor starter installations.

Frequently Asked Questions
How do I select the correct heater element for my motor?
Find the motor’s full-load amperage (FLA) on the motor nameplate. Match the FLA to the closest dial position on the H2010B-3: Position A = 6.75A, B = 8.17A, C = 9.58A, D = 11.0A. If your motor’s FLA is above 11.0A, the H2011B-3 (9.14–14.0A) is the next heater in the range. Call us at 1-800-222-5129 if you need help selecting the correct heater for your application.
What is the difference between H2010B-3 and H2011B-3?
The H2010B-3 and H2011B-3 are adjacent heater packs in the same Freedom Series range. The H2010B-3 covers 6.75A to 11.0A (dial positions A–D) and the H2011B-3 covers 9.14A to 14.0A (dial positions A–D). There is a small overlap between 9.14A and 11.0A where either pack could be used — in that overlap range, select the pack whose dial position most closely matches your motor’s exact nameplate FLA. For motors clearly above 11.0A, use H2011B-3.
How many heater elements are in the H2010B-3 package?
The H2010B-3 contains 3 heater elements per pack — one for each phase of a standard 3-phase motor starter. The “-3” suffix in the part number denotes a pack of 3. This is sufficient for a single complete motor starter installation.
Which Eaton overload relays is the H2010B-3 compatible with?
The H2010B-3 is compatible with Eaton Freedom Series 32A and 75A NEMA overload relays used in NEMA Size 00 through Size 2 motor starters (Series B and C). It is also compatible with Eaton Definite Purpose series overload relays of equivalent ratings. If you are unsure whether the H2010B-3 fits your specific relay, check the relay’s heater selection table or call us at 1-800-222-5129.
Is Cutler-Hammer H2010B-3 the same as Eaton H2010B-3?
Yes — Cutler-Hammer is a legacy brand that was acquired by Eaton. The H2010B-3 is sold under both brand names and refers to exactly the same heater pack. If your existing equipment documentation references “Cutler-Hammer H2010B-3”, the Eaton H2010B-3 available here is the correct replacement.
Is the H2010B-3 in stock for same-day shipping?
Yes — the H2010B-3 is a stocked item at Kent Electrical Supply’s warehouse in Emmaus, PA. Orders placed before 4:00 PM EST ship the same business day. Current stock quantity is shown on this page. For bulk pricing on multiple packs, call us at 1-800-222-5129 or text your RFQ to 484-425-0652.
