🔌 Recommended Hager RCCB 4-Pole Devices

Hager 4P RCD 40A 30 mA

• Compact 4-pole RCD for three-phase + neutral systems.

• 40 A, 30 mA sensitivity — ideal for personal shock protection in smaller three-phase boards. 

HAGER CD440B 40 A 4P 30 mA RCCB

• Standard 40 A, 30 mA earth-leakage breaker.

• Detects imbalance and quickly trips to protect against leakage to earth.

Hager CE440J RCCB 4P Type A 40 A 100 mA

• Type A residual current detection (better for circuits with electronics).

• 100 mA sensitivity and 40 A rating — suitable for mixed loads.

HAGER CD463B 63 A 4P 30 mA RCCB

• 63 A, 30 mA high-sensitivity 4P unit — good choice for larger three-phase loads needing good human-safety protection.

HAGER CE463B 63 A 4P 100 mA RCCB

• Same 63 A carry current but 100 mA sensitivity — less sensitive than 30 mA, useful for fire-hazard/leak monitoring in bigger panels. 

Hager 4P 63 A/100 A RCCB ELCB

• Higher-end multi-rating RCCB that can handle up to 100 A — good for main three-phase incomer protection.

Hager 40 A 4P 300 mA RCCB

• 40 A, 300 mA version — suitable where fire hazard protection is a priority over human-touch sensitivity.

Hager CFC684B RCCB 100 A 4P 300 mA

• 100 A, 300 mA earth leakage breaker — good for main three-phase distribution board earth-fault protection.

🧠 Quick Specs & Function (Typical for Hager 4P RCCBs)

• Poles: 4 (three phases + neutral). 

• Use: Detects earth leakage current (difference between currents in phases + neutral) and trips to prevent shock/fire risk. 

• Rated voltage: ~230/400 V AC for three-phase systems.

• Sensitivity options: 10 mA, 30 mA, 100 mA, 300 mA, 500 mA depending on model/use. 

• Rated current: Common available values 40 A, 63 A, 100 A — choose based on total load fed through the device.

• Standards: Conforms to IEC 61008 for residual current breakers. 

📌 Choosing the Right One

• 30 mA — Best for human shock protection (general residential/office).

• 100 mA — Good compromise for mixed circuits and panel feeds.

• 300 mA or 500 mA — Typical for fire hazard protection and larger distribution mains.

• Higher current ratings (63 A, 100 A) — For main incomer or heavy three-phase loads.
