2P 4P Electronic Type RCBO

Maximize safety in modern electrical installations with the CDADA DABL-63 2P 4P Electronic Type RCBO—a compact, intelligent residual current circuit breaker with overcurrent protection engineered by Shanghai DADA Electric CO., LTD. Designed for 2P (1+N) and 4P (3+N) applications, this electronic RCBO delivers four-in-one protection:

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

Overload protection,

Short-circuit interruption (6kA breaking capacity),

Surge suppression (integrated D-class varistor).

Ideal for outdoor sockets, garage lighting, basement circuits, and appliance feeders, the DABL-63 meets CE, CB, and RoHS standards and features an electronic differential module for ultra-sensitive fault detection. With a 2-module DIN width, independent contact position indicator, and –25°C to +40°C operating range, it’s built for reliability across diverse climates and residential/commercial settings.

Technical Data Sheet

Key Features:

★ Electronic differential module → high sensitivity & fast response

★ Independent contact indicator (shows true ON/OFF/trip status)

★ “TEST” button for monthly functionality check

★ Notched terminal clamps → lower heat, stronger grip

★ Cross-functional screws (+/–) → easier installation, no dropped parts

★ Silver-bearing contact alloy → longer life, lower resistance

Why Choose CDADA Electronic RCBO?

★ All-in-One Protection in 2 Modules

Replaces separate MCB + RCCB + surge protector—saving space, cost, and wiring complexity.

★ Enhanced Safety with Surge Suppression

Combined circuit with an electronic module of differential protection, D-class varistor and integrated circuit breaker of DAB7-63 series ensures 4 types of protection: from residual current (leakage current), short circuit; overload and surge overvoltage.

★ True Status Visibility

Unlike standard breakers, the independent contact indicator shows actual contact state—even if the handle is manually held ON.

★ Installer-Friendly Design

● Wide temperature range → suitable for unheated garages or hot attics

● Notched terminals → secure, low-resistance connections

● Dual-drive screws → works with flat or Phillips tools

★ Globally Certified

CE, CB, and RoHS approvals ensure compliance in Europe, Asia, Africa, and beyond—ideal for export panels.

★ Perfect for High-Risk Zones

Recommended for outdoor outlets, wet areas, garages, and basements where shock and fire risks are elevated.

★ With many years experience shipping to the Russia and European country in addition to all of South America, Europe, Asia, and Australia, CDADA has you covered!

Frequently Asked Questions (FAQ)

Q1: What’s the difference between an RCCB and an RCBO?

A1: An RCCB only detects residual (leakage) current—it does not protect against overload or short circuits. An RCBO (like DABL-63) combines RCCB + MCB in one device—offering leakage + overload + short-circuit protection.

Q2: Does this RCBO really protect against surges?

A2: Yes! It includes a built-in D-class varistor that suppresses transient overvoltages (e.g., from lightning or switching surges)—a rare feature in standard RCBOs.

Q3: Why choose an electronic RCBO over an electromagnetic one? A3:

● Electronic RCBOs offer higher sensitivity, smaller size, and can integrate extra functions (like surge protection).

● They require line voltage to operate—so not ideal if neutral is unreliable.

● Electromagnetic types work at 0V but are larger and lack smart features.
→ For stable residential grids, electronic RCBOs like DABL-63 are optimal.

Q4: Is 30mA sufficient for personal protection?

A4: Yes. 30mA is the international standard (IEC) threshold for life-saving shock protection in residential circuits.

Q5: Why choose CDADA for electronic RCBO?

A5: CDADA stands out because:

● True 4-in-1 protection (leakage + overload + short circuit)

● Compact 2-module design saves panel space

● Independent contact indicator ensures accurate status

● Global certifications (CE/CB/RoHS)

● OEM-ready: consistent quality, English support, bulk pricing
