RCCB leads Protector Type at 34.0%; 30 mA leads Sensitivity at 47.0%.

Which Protector Type dominates?

RCCB holds 34.0% share in 2026.

RCCB is expected to hold 34.0% share in 2026 due to its established role in detecting earth-leakage faults across household and similar circuits. RCBO gains where installers want residual-current and overcurrent protection in one device. Electronic RCDs are used where diagnostics or faster sensing add value. IEC 61008-1:2024 covers RCCBs with rated currents up to 125 A and rated operational voltages up to 440 V AC for household and similar applications, principally for protection against shock hazards.

What leads the Sensitivity segment?

30 mA holds 47.0% share in 2026.

30 mA is projected to account for 47.0% share in 2026 because it is widely used for personal protection in socket, bathroom, outdoor and charger-adjacent circuits. 100 mA and 300 mA devices are selected more often for upstream or fire-risk protection. 6 mA DC detection is tied to EV charger and power-electronics circuits. Schneider Electric lists Acti9 RCCB products with 30 mA sensitivity and 125 A ratings, showing the standard catalog depth behind this sensitivity band.

How does Application shape demand?

Residential holds 32.0% share in 2026.

Residential is anticipated to capture 32.0% share in 2026 as homes add EV chargers, rooftop solar and heat pumps to existing boards. Commercial buildings follow because offices, retail premises and parking areas need selective protection. Industrial use places more weight on 300 mA and Type B coordination near drives. The UK Department for Transport reported that 121,171 public EV chargers were available across the United Kingdom as of 1 July 2026.

What supports demand for 2-pole within Pole?

2-pole holds 41.0% share in 2026.

2-pole is estimated to represent 41.0% share in 2026 led by single-phase boards in residential and small commercial use. 1P+N devices gain attention where electricians need compact layouts. 4-pole devices serve three-phase applications and upstream protection in larger sites. Eaton lists xEffect FRBdM RCBO products with a rated switching capacity of 10 kA under IEC/EN 61009, alongside specified pole configurations and residual-current ratings.

EV charging drives it; device-selection complexity restrains it.
