CHH3100H4 - 100Amp Circuit Breaker

CHH3100H4 - 100 Amp Circuit Breaker

The CHH3100H4 molded case circuit breaker is designed to provide dependable circuit protection in commercial and industrial electrical distribution systems that require a 3-pole, 100-amp breaker with a 42kA interrupting capacity at 240VAC. Built on the CHH4 frame platform, this breaker features a non-interchangeable trip unit, meaning the trip mechanism is factory-matched to the breaker and not intended for field replacement. This design helps maintain consistent protection characteristics for the circuit it serves. Molded case breakers like the CHH3100H4 are commonly used to safeguard electrical panels, feeders, and equipment from overloads and short circuits. With its defined form and fit, this breaker is often used as a functional replacement in existing systems where a compatible CHH4 frame breaker is required. These breakers are built to last and are widely used in facilities that rely on proven electrical infrastructure.

Key Features and Benefits

Where It Works Best

• The CHH3100H4 breaker is commonly used in commercial buildings, industrial facilities, and institutional power distribution systems that utilize CHH4 frame molded case breakers. It is suitable for installation in panelboards, switchboards, and distribution equipment where a 3-pole, 100-amp breaker rated for 240VAC with 42kA interrupting capacity is required. Electricians and maintenance teams often select this model when maintaining or servicing existing electrical systems that require the same form, fit, and electrical ratings as the original breaker.
