Rated Voltage (Ue): 230/400 V AC

Rated Residual Operating Current (IΔn): 30 mA (Type A — detects AC and pulsating DC residual currents)

Rated Residual Non-Operating Current (IΔn/2): 15 mA (guaranteed no-trip)

Breaking Capacity (Icm): 3 kA (conditional)

Number of Poles: 2P (230 V single-phase) / 4P (400 V three-phase) — selectable

Trip Time at IΔn: ≤ 300 ms (standard); ≤ 150 ms (S-type variant)

Rated Frequency: 50/60 Hz

Mechanical Life: 10,000 operations

Electrical Life: 4,000 operations

Connection: Screw terminal, 1–25 mm² wire capacity (top and bottom)

Mounting: 35 mm DIN rail (EN 60715)

Protection Class: IP20 (front); IP40 with cover

Operating Temperature: -25°C to +40°C (standard); -5°C to +40°C (electronic variant)

Standards: IEC 61008-1, EN 61008-1, VDE 0664

Housing Material: Polyamide 6.6, flame-retardant (UL94 V-0)

Dimensions (W × H × D): 36 mm × 85 mm × 68 mm (2-pole); 72 mm × 85 mm × 68 mm (4-pole)

Weight: 180 g (2-pole); 320 g (4-pole)

Key Features:

• Type A detects residual currents from inverter-fed loads (VFDs, UPS, EV chargers)
• Test button (T) verifies trip function monthly — presses test resistor into circuit
• Must be installed upstream of MCBs for personnel protection
• Immune to nuisance tripping from normal leakage up to IΔn/2

Applicable Industries: Residential buildings, commercial facilities, hospitals, data centers, EV charging stations

Installation Requirements:

• Install at origin of installation (main switchboard) or sub-distribution board
• Connect line (L) to top terminals, load to bottom terminals — do not reverse
• Neutral (N) must pass through RCD — do not bypass
• Tighten terminals to 2.5 Nm

Usage Notes:

• Press TEST button monthly — if breaker does not trip, replace immediately
• RCD protects persons only — does NOT protect against overcurrent or short circuit
• Must be used in combination with MCB (e.g., AEG 6728 series)
• After trip, identify and eliminate fault before resetting
