Abb Differential Block DDA202 2P 40A 30mA Type A 2M

The differential lock is designed to protect people from electric shocks caused by earth leakage. In the event of a fault, it immediately breaks the circuit, preventing electrocution and danger of macro electric shock.

Type A differential lockout: maximum reliability

Being a type A device, it is capable of detecting and intervening in case of sinusoidal alternating differential currents and unidirectional pulsating currents. This feature makes it ideal for applications in modern installations where advanced electronic equipment is present.

Simple and safe installation

The differential block is quickly installed on thermal-magnetic circuit breakers, thanks to a handy plastic clamp on the side. The mounting system is designed to prevent mating errors, ensuring that the power rating of the block is always equal to or greater than that of the associated circuit breaker.

Reliability and durability

This device is built for long operating life, with an electrical endurance of up to 10,000 cycles. It is capable of operating in environments with temperatures ranging from -25 to +55 degrees, maintaining high and consistent performance over time.
