Product FAQs
6 answersWhat equipment is the Eaton CVH3225X3 designed to be installed in?
This 3-pole main breaker is specifically designed for use in Eaton 35MM and 37MM modular meter stacks.
What are the wire size requirements for the CVH3225X3?
The factory-installed lugs accommodate a wide range of conductors, accepting 1 AWG to 300 kcmil copper or aluminum (Cu/Al) wire to support its 225A rating.
How is the CVH3225X3 secured within the meter stack?
It utilizes a bolt-on connection type, which provides a secure, vibration-resistant mechanical and electrical connection to the busbars in compatible Eaton metering equipment.
Can the CVH3225X3 be used in systems with high fault currents?
Yes, this breaker features a high interrupting rating of 100kAIC at 240VAC, allowing it to safely clear severe short circuits in commercial or multi-tenant metering applications.
How does the trip mechanism on the CVH3225X3 operate?
It uses a fixed thermal-magnetic trip unit. The thermal component responds to sustained overloads for long-time protection, while the magnetic component reacts immediately to short circuits for instantaneous protection.
Is the CVH3225X3 suitable for use with aluminum wiring?
Yes, the standard lugs on this breaker are dual-rated for both copper (Cu) and aluminum (Al) conductors.
