EHB3070 - 70Amp Circuit Breaker

EHB3070 - 70 Amp Circuit Breaker

If you’re working on an older panel and need a breaker that fits right the first time, the EHB3070 circuit breaker is exactly the kind of component you’re looking for. Built for electrical systems manufactured prior to 1989, this unit is all about compatibility—matching the original design so you can restore protection without modifying the panel. This 70 amp, 3-pole breaker uses a thermal-magnetic trip mechanism to handle both overloads and short circuits in a straightforward, dependable way. It’s rated for 480VAC with a 14kA interrupting capacity, making it suitable for a wide range of commercial and industrial setups still operating on legacy equipment. The fixed, non-interchangeable trip unit keeps things simple and consistent, while the included load terminals help streamline installation when time matters. It’s not about reinventing your system—it’s about keeping it running the way it was designed to.
