Product Overview
The ABB F204 A‑40/0.3 is a 4‑pole Type‑A electromagnetic residual‑current circuit‑breaker of F200‑series. It monitors earth‑fault residual‑current on three‑phase‑plus‑neutral circuits and instantaneously cuts off power when leakage current reaches 300 mA. Type‑A can respond to both AC leakage and pulsating DC leakage caused by frequency converters, rectifier loads. Important note: this unit provides earth‑fault protection only, it does NOT protect against overload or short‑circuit; upstream over‑current protective device is mandatory. It mitigates fire risk from high‑level earth‑fault in commercial and light‑industrial distribution systems. Electrical panel builders and maintenance technicians benefit from robust electromagnetic design, DIN‑rail compact form, drop‑in spare replacement for existing F200‑series installations.
Application Scenarios
- Industrial MCC & distribution cabinets: Main or branch earth‑fault fire‑protection for three‑phase loads including VFD, rectifier‑driven equipment, where pulsating DC leakage may occur.
- Commercial building power distribution: 3‑phase power inlet leakage‑fire protection for shopping malls, workshops, HVAC equipment.
- Marine and off‑shore auxiliary distribution cabinets: Suitable for mixed rectifier‑type loads, Type‑A covers pulsating DC residual‑fault.
