ETIPOWER EPL/EPH Air Circuit Breakers: Advanced Protection for Demanding Applications

ETIPOWER EPL and EPH series of Air Circuit Breakers (ACBs) — a versatile, high-performance solution designed to meet the needs of modern industrial facilities, data centers, and electrical equipment manufacturers.

Powerful and Flexible Performance

The EPL/EPH series offers breaking capacities up to 150 kA (at 500 V, EPH D Frame) and is built with 100% neutral phase current capacity, ensuring safe handling of system imbalances and harmonics. With dual models, compact design, and versatile terminal orientation (horizontal or vertical), these ACBs offer unmatched flexibility for panel design and system integration.

• A-Frame: 630 A to 1600 A

• B-Frame: 2000 A to 3200 A

• EPH Series: up to 6300 A

• Rated impulse withstand voltage (Uimp): 12 kV

Advanced Protection with OCR Technology

The series features a powerful Overcurrent Relay (OCR), with multiple types to match your application needs:

• N Type: NFC-enabled, self-powered, fault and waveform recording via mobile app

• A Type: MODBUS communication, 256 event memory, earth fault detection via external CT/ZCT

• P Type: Full protection including over/under voltage, energy monitoring, power factor display

• H Type: Real-time 3-phase waveform view, harmonics analysis up to the 63rd order

All versions include long-time, short-time, instantaneous, and ground fault protection.

Built for Safety, Maintenance, and Retrofit

• Integrated draw-in/out handle for easy maintenance

• Standard counter and temperature sensor built-in

• SHT and UVT coils available for all common voltages

• Mechanical interlock option for up to 3 devices
