ABB NTR002-A is a series of residual current circuit breakers (RCCBs) manufactured by ABB. RCCBs are used to protect people from electric shock in the event of a fault. They do this by monitoring the current flowing in a circuit and tripping if there is a difference between the current flowing in and out of the circuit. This indicates that there is a fault and that the circuit needs to be isolated.

ABB NTR002-A RCCBs are available in a range of ratings, from 25A to 125A. They are also available with a variety of features, such as test buttons, auxiliary contacts, and overload protection.

The following are some of the key features of ABB NTR002-A RCCBs:

• High sensitivity: ABB NTR002-A RCCBs are highly sensitive and can detect even the smallest of current leaks. This makes them ideal for protecting people from electric shock.
• Fast tripping time: ABB NTR002-A RCCBs have a fast tripping time, which means that they will trip quickly in the event of a fault. This helps to protect people from serious injury.
• Wide range of ratings: ABB NTR002-A RCCBs are available in a wide range of ratings, from 25A to 125A. This means that there is a suitable RCCB for most applications.
• Variety of features: ABB NTR002-A RCCBs are available with a variety of features, such as test buttons, auxiliary contacts, and overload protection. This makes them a versatile and adaptable solution for a range of applications.
