4-10 HP Tecumseh 3-Phase Motor Thermal Overload Protector Klixon 35HM 235-4 [60]:
$36.50

Device Type: Hermetically sealed, 3-phase, line-break, automatic-reset thermal motor protector.

Primary Application: Designed for direct on-winding installation on WYE (Star) wound 3-phase motors (typically 4 to 10 HP), widely used in commercial refrigeration compressors, air conditioning units, and submersible pumps.

Function: Monitors winding temperature to protect against over-temperature conditions caused by loss of refrigeration charge, locked rotor (low voltage), or single phasing (loss of phase).

Construction: Small, rugged, welded housing designed for close coupling directly to motor windings.

Pressure Rating: Rated up to 1600 PSIG (110 Bar), making it suitable for both high-side and low-side hermetic refrigeration environments.

Action: Utilizes a snap-action bimetallic disc for positive make/break performance with controlled temperature differentials.

The base designation 35HM identifies the product line and housing style, while the specific suffix numbers (235-4) represent the OEM-specific factory calibration, precise opening/closing temperature set-points, and lead configuration tailored for a particular compressor or motor brand.

Compressor Types: Used on Tecumseh 3-phase (WYE/Star-wound) commercial compressors, typically in the 4 to 10 HP range found in large reach-in coolers, commercial freezers, packaged A/C units, and condensing systems.
Engineering Reference: Tecumseh lists the 35HM series (including specific calibrations like the 235-4 suffix) within their engineering and selection software (such as Tecumseh TSelect) for 3-phase commercial models.

On-Winding Installation: Mounted directly onto the internal motor windings to provide close-coupled temperature monitoring rather than relying solely on external pilot controls.
Line-Break Protection: Wired into the neutral centerpoint of the 3-phase motor to directly interrupt line current when trip temperatures are reached.
Failure Mode Defenses: Specifically guards Tecumseh compressors against extreme thermal conditions caused by:

Single-phasing (loss of a phase line).
Loss of refrigeration charge (running hot/starving).
Low-voltage locked-rotor events.
