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.
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.
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.
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.
