Differential block ABB DDA204 4P 63A 300mA type A/S 2 modules B428002

Differential locks are mechanically designed to prevent incorrect coupling between the lock and the switch: the power of the lock must always be equal to or greater than that of the circuit breaker. The lateral plastic clamp allows for faster assembly of the block on the circuit breaker and a button prevents possible interventions. It is used to protect human health in the event of an earth fault (electrical leakage) or phase-to-earth electrocution, thus also providing protection against macro electric shocks, both direct and indirect, on exposed persons. The differential block type AS: selective or delayed differentials: they operate with intentional delay (like type A).
