H2113B-3

What type of component is this?

This is a Freedom/Definite Purpose heater pack designed for use with compatible motor starter overload relays. It helps the overload relay respond when motor current remains above the selected operating range.

What is the full-load current range?

The H2113B-3 provides four full-load current settings: 18.7 A, 21.8 A, 25 A and 28.1 A.

How are the current settings selected?

The four dial positions correspond to specific current values: position A is 18.7 A, B is 21.8 A, C is 25 A and D is 28.1 A.

Which overload relay ratings are compatible?

This heater pack is specified for use with compatible 32 A or 75 A overload relays. The relay and starter series should also be checked before installation.

Which motor starter sizes can use this heater pack?

It is intended for starter sizes 00–0 Series C and sizes 1–2 Series B. It can also be used with IEC sizes A–F Series C and IEC sizes G–K Series B.

Is this heater pack suitable for both NEMA and IEC equipment?

Yes. Its design supports specified NEMA and IEC starter configurations, provided the starter size, series and overload relay rating match the stated compatibility requirements.

What trip classification does it use?

It has a fast-trip, Class 10 characteristic. This classification is commonly used where the overload relay needs to respond relatively quickly to sustained overcurrent.

What applications is this component commonly used in?

It is commonly used in motor-control assemblies containing compatible definite-purpose or Freedom-style starters, including machinery, pumps, fans, conveyors and other industrial motor loads.

How should the correct dial position be chosen?

Select the dial position by matching the motor's nameplate full-load current with the available settings. The starter series, overload relay rating and application requirements must also be considered.

Can it be used if the motor current falls between two dial settings?

The chosen setting should follow the motor and overload-relay selection requirements for the application. If the nameplate current does not correspond appropriately with 18.7 A, 21.8 A, 25 A or 28.1 A, a different heater pack may be required.

Does this component provide short-circuit protection?

No. A heater pack forms part of an overload protection arrangement and is not a substitute for correctly rated branch-circuit short-circuit protection.

What should be checked when replacing an existing heater pack?

Confirm the current setting, overload relay rating, starter size, starter series, NEMA or IEC configuration and Class 10 trip requirement. Matching only the physical appearance is not sufficient.

Does the heater pack switch the motor on and off?

No. The contactor or starter performs the motor switching. The heater pack works with the overload relay to detect sustained current conditions that may require the starter circuit to open.

What certifications are associated with this component?

The available specification information identifies the heater pack as UL Listed and CSA Certified.
