ABB 2CSB204001R1400 DDA204 AC-40/0.03 4P 40A 30mA Type AC Residual Current Circuit Breaker Module

The ABB DDA204 AC-40/0.03 (SKU: 2CSB204001R1400) is a 4-pole residual current circuit breaker (RCCB) module from the DDA200 series, rated at 40A with a 30mA sensitivity for Type AC earth-fault protection. Designed for integration into control panels and distribution boards, this module detects sinusoidal alternating residual currents and disconnects the circuit to protect personnel and equipment. Compact at 105mm × 93mm × 69mm and weighing just 175g, the DDA204 AC-40/0.03 is engineered to meet IEC 61009 and EN 61009 standards for demanding industrial and commercial installations.
