2P 4P Electromagnetic RCBO

For uncompromising safety in environments where power reliability is uncertain, Shanghai DADA Electric CO., LTD. presents the CDADA DABF-63 2P 4P Electromagnetic RCBO a true 2P/4P electromagnetic residual current circuit breaker with overcurrent protection that operates without any electronic components or external power supply. Designed to IEC standards, this RCBO provides three essential protections in one device:

★ Electric shock prevention (via 30mA residual current detection),

★ Overload protection (thermal mechanism),

★ Short-circuit interruption (magnetic release, 6kA).

Recommended for outdoor sockets, garages, basements, and rural installations, the DABF-63 continues to function even if neutral is lost, voltage collapses, or during blackouts—a critical advantage over electronic alternatives. With an independent contact position indicator, –25°C to +40°C operating range, and robust terminal design, it delivers fail-safe performance where it matters most.

Why Choose CDADA Electromagnetic RCBO?

★ Works Without Power – Ever

Unlike electronic RCBOs, our 2P 4P Electromagnetic RCBO requires no line voltage to detect leakage—ensuring protection during neutral failure, brownouts, or complete outages.

★ Ideal for Harsh or Remote Locations

Perfect for rural areas, construction sites, farms, tunnels, and regions with unstable grids where electronic devices may malfunction.

★ Inherently Fail-Safe

No semiconductors = no aging, no software errors, no EMI sensitivity. Just proven electromagnetic physics.

★ Clear Operational Status

The independent contact indicator shows actual contact state—critical for maintenance and safety audits.

★ Compact & Reliable

2-module size saves panel space, while silver-alloy contacts and robust terminals ensure long service life.

★ Global Compliance

Certified to IEC, CE, and CB standards—trusted for export and international projects.

★ Since it is our policy to 100% inspect all products that leave our facility, we can guarantee with absolute certainty that the product is functionally 100% accurate before it leaves our facility.

★ We will continue to build our technological expertise by investing in equipment, processes, people, and certifications that will be reflected in our product and ultimately in our customer satisfaction.

Typical Applications

Rural Electrification Projects

Outdoor Sockets & EV Charging Points (basic layer)

Garages, Basements & Workshops (damp, cold environments)

TT Earthing Systems (where neutral integrity is poor)

Backup Circuits & Emergency Panels

Frequently Asked Questions

Q1: What’s the difference between electronic and electromagnetic RCBOs?

A1:

Q2: Does this RCBO provide surge protection?

A2: No. True electromagnetic RCBOs do not include varistors or surge suppression—those require electronic components. If surge protection is needed, pair it with a separate SPD (surge protective device).

Q3: Is 30mA sufficient for personal shock protection?

A3: Yes. 30mA is the IEC standard threshold for life-saving protection against direct contact in residential and commercial circuits.

Q4: Can it be used as main incomer protection?

A4: Yes—with 6kA breaking capacity, the DABF-63 can serve as incoming protection in small distribution boards, especially in TT systems.

Q5: Why choose CDADA for electromagnetic RCBO?

A5: CDADA offers:

● Genuine electromagnetic design (no hidden electronics)

● True 0V operation capability

● 2-module compact size—rare for electromagnetic types

● Independent contact indicator for safety verification

● Global certifications (CE/CB) and OEM-ready support
