KH36090 - 90 Amp Circuit Breaker

KH36090 - 90 Amp Circuit Breaker

Servicing an I-Line panelboard involves looking at the entire breaker, not just its amperage rating. The KH36090 is a 90-amp, 3-pole Type KH molded-case circuit breaker with a thermal-magnetic design, suitable for 60Hz and 40°C operation. When its specs match your requirements, the KH36090 can be an ideal choice for your application.

Key Features and Benefits

• 90-amp rating: Suited to applications specifically requiring a 90A breaker configuration.
• Three-pole design: Provides the 3-pole arrangement specified for compatible electrical equipment.
• Type KH molded case circuit breaker: Gives maintenance personnel a clear breaker type to verify against existing equipment.
• For I-Line panelboards: Intended for use with compatible I-Line panelboard applications requiring this breaker configuration.
• Thermal-magnetic configuration: Matches equipment specifications requiring a thermal-magnetic molded-case circuit breaker.
• 60Hz and 40°C specifications: Provide additional operating details that can be checked against the intended application.

Material Compliance and Certifications

No specific third-party certification or material-compliance information was included in the supplied specifications for the KH36090. For that reason, certifications or compliance standards such as UL, RoHS, or REACH should not be assumed from the available information.

Where It Works Best

The KH36090 is intended for compatible I-Line panelboards, particularly in existing and legacy electrical systems where this Type KH configuration is required. It can be considered for functional replacement applications when its electrical ratings and physical characteristics correspond with the equipment already in service.

For a proper match, verify more than the 90A rating. Check the KH type, three-pole configuration, 60Hz frequency, 40°C specification, physical dimensions, panelboard requirements, and the appropriate AIC rating for the system voltage. Matching these characteristics helps establish whether the KH36090 has the necessary form, fit, and function for the application.
