Frequently Asked Questions - JN212B HAGER

What type of device is the Hager JN212B?

The Hager JN212B is a miniature circuit breaker (MCB) used for overcurrent protection in electrical installations.

What are the dimensions of the JN212B?

The dimensions are approximately 80 x 36 x 70 mm (height x width x depth), suitable for standard DIN rail mounting.

What is the rated current of the JN212B?

The rated current is 12 A, making it suitable for circuits with a maximum load of 12 amps.

What voltage can the JN212B handle?

It is rated for 230/400 V AC, typically used in single-phase or three-phase systems.

What is the breaking capacity of the JN212B?

The breaking capacity is 6 kA (6,000 amps) under standard conditions.

How do I install the JN212B?

It clips onto a DIN rail. Ensure the circuit is de-energized before installation. Connect the line and load wires to the appropriate terminals.

Is the JN212B repairable?

No, it is a sealed unit and should be replaced if faulty. There are no user-serviceable parts.

What certification does the JN212B have?

It carries CE and UKCA markings, complying with relevant European and UK safety standards.

Can the JN212B be used in outdoor installations?

It has an IP20 rating, meaning it is not protected against water. Use it indoors or in a weatherproof enclosure.

What is the difference between the JN212B and other MCBs?

The JN212B is a B-curve MCB with a rated current of 12 A. B-curve trips at 3-5 times the rated current, ideal for resistive or lighting loads.
