Eaton / Cutler-Hammer CHH2200H2X Molded Case Circuit Breaker

This breaker is designed for installation as a tenant main disconnect in Eaton modular metering stacks. Supported series include 1MP, 1MM, 35MM, 37MM, 35SS, and 37SS enclosures.

The lugs accept #2 AWG to 300 kcmil copper or aluminum wire. When terminating aluminum conductors, carefully strip the insulation, clean the stripped portion with a wire brush, and apply a corrosion-inhibiting joint compound if directed by the product label before torquing the lug.

Torque specifications vary based on the exact wire gauge installed. Refer to the specification label printed directly on the side of the circuit breaker and use a calibrated torque wrench to apply the correct inch-pound value.

The LI code means this fixed thermal-magnetic breaker provides Long-Time and Instantaneous protection. The long-time function handles thermal overloads, while the instantaneous function trips the breaker during short circuits.

This is a bolt-on circuit breaker. It must be securely bolted to the internal bus of the modular metering stack to serve as a tenant main disconnect, ensuring a high-capacity connection.

Always de-energize the main feed to the entire metering stack before installing or servicing tenant breakers. Verify that the bus connections are clean, properly align the breaker before bolting it down, and ensure all load-side terminations are torqued to the manufacturer specifications.

No. Metering stacks are UL listed for specific breaker frames. You must use the exact frame type (CHH) printed on the interior label of your Eaton modular metering enclosure to maintain the UL listing and ensure proper fitment.

The CHH2200H2X provides a 25,000 Ampere Interrupting Capacity (25kAIC) at 240V. You must verify that the available fault current at your specific installation site does not exceed this rating. If a higher interrupting capacity is required, a different breaker series or upstream current limiting may be necessary.
