Product Features
- Pack of 3 Heater Elements: The H2011B-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 (9.14A, 10.8A, 12.4A, 14.0A) 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 — H2012B-3: The H2011B-3 covers FLA up to 14.0A. If your motor’s FLA is at or above 14.0A, the H2012B-3 (14.0–22.8A) is the next heater pack in the range.
- Also Known as Cutler-Hammer H2011B-3: This heater pack is sold under both the Eaton and Cutler-Hammer brand names. Both refer to the same part — Cutler-Hammer is a legacy brand now part of Eaton.
- UL Listed: 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 H2011B-3: Position A = 9.14A, B = 10.8A, C = 12.4A, D = 14.0A. If your motor’s FLA falls between two dial positions, select the closest position to the actual nameplate FLA. If the motor FLA is above 14.0A, the H2012B-3 (14.0–22.8A) is the next heater in the range. Call us at 1-800-222-5129 if you need help selecting the correct heater.
What is the difference between H2011B-3 and H2012B-3?
The H2011B-3 and H2012B-3 are adjacent heater packs in the same Freedom Series range — they differ only in FLA coverage. The H2011B-3 covers 9.14A to 14.0A (dial positions A–D) and the H2012B-3 covers 14.0A to 22.8A (dial positions A–D). Both use the same overload relays, same NEMA starter sizes, and same Class 20 trip rating. Select based on your motor’s nameplate FLA — if the FLA is at or below 14.0A use H2011B-3, if above 14.0A use H2012B-3.
How many heater elements are in the H2011B-3 package?
The H2011B-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 H2011B-3 compatible with?
The H2011B-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 H2011B-3 fits your specific relay, check the relay’s heater selection table or call us at 1-800-222-5129.
Is Cutler-Hammer H2011B-3 the same as Eaton H2011B-3?
Yes — Cutler-Hammer is a legacy brand that was acquired by Eaton. The H2011B-3 is sold under both the Eaton and Cutler-Hammer brand names and refers to exactly the same heater pack. If your existing equipment documentation references “Cutler-Hammer H2011B-3”, the Eaton H2011B-3 available here is the correct replacement.
Is the H2011B-3 in stock for same-day shipping?
Yes — the H2011B-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.
