Product FAQs
6 answersWhy is my existing E2070 breaker labeled Westinghouse while replacements may say Eaton or Cutler-Hammer?
Eaton acquired the Westinghouse electrical distribution business in 1994. Breakers bearing the E2070 catalog number under the Westinghouse, Cutler-Hammer, or Eaton brands are physically and electrically identical and can be used interchangeably in the same panelboards.
Which panelboards are designed to accept the E2070 circuit breaker?
This bolt-on breaker is compatible with legacy Westinghouse panelboards, Eaton Pow-R-Line panelboards, and AB De-Ion panels. It requires a bolt-on connection and cannot be used in load centers designed for plug-on breakers.
Can the E2070 be used in direct current (DC) applications?
Yes, this thermal-magnetic breaker carries a DC interrupting rating of 5kA at 125/250VDC. Always verify that your specific DC application and panelboard are rated for this interrupting capacity before installation.
What is the maximum interrupting capacity for the E2070 on AC systems?
The E2070 has a maximum interrupting rating of 7kAIC at 240VAC. It is not suitable for systems with higher available fault currents, so you must verify your system requirements before installation.
What wire sizes are accepted by the lugs on the E2070 breaker?
The factory lugs accept wire gauges from 14 AWG up to 1/0 AWG. The terminals are rated for both copper (Cu) and aluminum (Al) conductors. Ensure you apply the correct torque as specified on the breaker label during installation to prevent loose connections.
What type of protection does the E2070 provide?
It features a fixed thermal-magnetic trip unit. The thermal component provides long-time protection against sustained overloads, while the magnetic component offers instantaneous protection against short circuits. Both trip settings are fixed from the factory and cannot be adjusted.
