89114220SP

Overview

The Hoffman Enclosures Inc. model 89114220SP is an encapsulated compressor overload protection device. It functions as a thermal safety component designed to interrupt electrical circuits in response to excessive temperatures within compressor systems. The unit is engineered for industrial applications requiring reliable thermal management and equipment protection against overheating conditions.

Feature Summary

• Encapsulated construction for environmental protection
• Designed specifically for compressor overload scenarios
• Provides thermal circuit interruption

Applications

• Industrial compressor thermal protection
• Refrigeration system safety circuits
• HVAC compressor motor protection

Procurement Notes

Verify the specific current rating and voltage class required for your compressor application against the official datasheet specifications. Confirm physical mounting dimensions and terminal configuration compatibility with existing control panels. Ensure the replacement part matches the original equipment manufacturer's thermal curve requirements to maintain system safety compliance.

Selection Notes

Select this component based on its specific role as an encapsulated overload protector rather than a general-purpose switch. Evaluate the thermal characteristics necessary for the target compressor type. Ensure the enclosure environment does not exceed the device's operational temperature limits. Compatibility with the specific compressor model's electrical parameters is critical for proper function.

Part Context

This component belongs to the Hoffman Enclosures product line, which specializes in industrial enclosure systems and related protective hardware. While primarily known for metal enclosures, the portfolio includes essential electrical protection components like thermal overloads used within or alongside their enclosure solutions for complete system integration.

Replacement Considerations

Ensure any substitute part matches the exact encapsulation style and thermal trip characteristics. Verify terminal orientation and mounting hardware compatibility. Generic compressors may require different thermal profiles; consult the original equipment manual for approved replacement part numbers.
