What type of electrical component is this?
This is a 2-pole miniature circuit breaker designed to protect electrical circuits against overloads and short circuits in low-voltage installations.
What current rating does this miniature circuit breaker have?
It has a rated current of 10 A, making it suitable for circuits where a 10 amp protective device is required.
What does the D tripping characteristic mean?
The D characteristic means the breaker is designed for circuits with higher inrush currents, such as those found with certain motors, transformers or equipment that may draw a brief surge when energised.
How many poles does this circuit breaker have?
It is a 2-pole device, meaning it can disconnect two conductors at the same time when tripped or manually switched off.
What voltage is this breaker rated for?
The breaker is rated for 400 V AC supply applications and can operate with multi-phase AC systems up to 440 V.
What is the rated breaking capacity?
The rated breaking capacity is 10 kA according to EN 60898 and IEC 60947-2, allowing it to interrupt fault currents up to that level within its specified operating conditions.
Can it be used in DC applications?
Yes, the datasheet specifies DC operation up to a maximum rated value of 72 V DC, provided the installation conditions are suitable.
What is the frequency range for AC operation?
The breaker is suitable for AC supply frequencies of 50/60 Hz.
What enclosure protection rating does it have?
With connected conductors, the device has an IP20 protection rating, which is typical for modular protective devices installed inside suitable distribution boards or enclosures.
What conductor sizes can be connected?
The terminals accept solid, stranded and finely stranded conductors with core end processing from 0.75 mm² to 25 mm².
What tightening torque should be used on the screw terminals?
The specified tightening torque range for the screw terminals is 2.5 N·m to 3 N·m.
