ED43B070L - 70Amp Circuit Breaker Description
ED43B070L - 70Amp Circuit Breaker
When you need a compatible replacement circuit breaker to keep your electrical system operating as designed, the Siemens ED43B070L delivers the ratings and configuration your installation depends on. This 70 Amp, 3-pole molded case circuit breaker is built for 480V AC commercial and industrial power distribution systems and uses a thermal-magnetic trip unit to help protect equipment from both overloads and short circuits. Whether you're performing scheduled maintenance, replacing a failed breaker, or servicing existing equipment, the ED43B070L is designed as a form, fit, and functional replacement for compatible Siemens ED frame installations.
The breaker features an 18kA interrupting capacity (18kAIC) at 480V AC, making it suitable for applications requiring this fault current rating. It also comes with factory-installed line and load side lugs (LN1E100) that accept 10 AWG through 1/0 AWG copper or aluminum conductors, helping simplify installation in compatible systems.
