ABB DDA 200 A Series RCD Switch, 40A, 3-Pole, 30 mA Trip Sensitivity, Type A, 400V AC 2CSB203101R1400 - DDA203A-40/0,03

ABB 2CSB203101R1400-DDA203A-40/0,03 RCD Switch from the DDA 200 A Series combines advanced earth leakage detection with robust electrical protection. Designed for industrial, commercial, and residential installations, this device supports a 40A rated current and 3-pole switching suitable for three-phase AC systems.

The Type A earth leakage protection distinguishes this switch by its ability to detect both sinusoidal alternating and direct pulsating currents, making it ideal for modern electrical installations with mixed load types. It operates at a rated voltage of 400V AC and includes a 30mA trip sensitivity to rapidly interrupt circuits under hazardous leakage conditions, significantly enhancing personnel and equipment safety.

This RCD switch offers an instantaneous break time for fast response to faults, backed by a breaking capacity of 0.3A. The toggle switch actuator allows simple manual resetting of the device post-trip, while the integrated DIN rail mount facilitates easy installation and modular system construction with compatible S200 series MCBs.

Screw terminal connections provide reliable and secure wiring, even in mechanically vibrating environments, while the unit complies with CE safety approvals, underscoring its high-quality manufacturing standards. Its compact dimensions (87mm width, 80mm height, 76mm depth) make it suitable for various electrical distribution panels.

Applications include escalators, lifts, barriers, gates, and conveyor belts, where safety against earth leakage is critical. The product's robust performance across a wide temperature range (-25°C to +55°C) supports demanding industrial conditions.

Protects against alternating and pulsating direct earth fault currents effectively. Instant response enhances safety for connected industrial and commercial electrical equipment. Easy installation and maintenance supported by DIN rail mount and toggle actuator.

Secure wiring connections with screw terminals ensure operational reliability. Conforms to CE standards, ensuring compliance with international safety norms.
