HKB3175T - 175Amp Trip Unit Description
HKB3175T - 175Amp Trip Unit
The HKB3175T thermal-magnetic trip unit is a 175-amp component designed for use with compatible KB and HKB frame circuit breakers. It is commonly used in maintenance and replacement projects where keeping your existing electrical equipment in service is important. Instead of replacing an entire breaker assembly, this trip unit helps maintain the original system configuration by matching the required frame type and trip function.
With a thermal magnetic design and an adjustable magnetic hi-low trip setting range of 875-1750 A, this trip unit supports established circuit breaker assemblies that require a compatible replacement component. When installed correctly within the proper frame, the HKB3175T is built for long-term use in properly maintained electrical distribution equipment.

Material Compliance and Certifications
The HKB3175T thermal magnetic trip unit should be installed in accordance with the requirements of the compatible circuit breaker assembly and all applicable electrical codes and standards. Frame compatibility and trip settings should be verified before installation to ensure proper fit and function. Compliance details should be confirmed through product markings and available manufacturer documentation.
Where It Works Best
The HKB3175T is well suited for commercial buildings, industrial facilities, and electrical maintenance environments where compatible KB or HKB frame circuit breakers are already installed. It works best in applications where maintaining an existing breaker assembly is important and a properly matched trip unit is required.
