Datasheet
**3120-N...-...T1-... Thermal Circuit Breaker** ## **Description** Lo The 3120-N...-...T1-... thermal circuit breaker/switch combination unites overcurrent protection and the function of an ON/OFF switch within a single component. The trip element is a thermobimetal. Type 3120-N...-...T1-... is ideally suited for overload protection of motors, pumps, transformers and cables. After tripping, it can reliably, easily and quickly be reset. The positively trip-free mechanism ensures reliable disconnection of the circuit even with the actuator blocked. The 3120-N type is also available with thermal-magnetic trip. (technical data p. 21 ff.) Type 3120-N is also available as a switch in accordance EN IEC 61058 (see data sheet switch 3120-N...Q1). **==> picture [79 x 8] intentionally omitted <==** **----- Start of picture text -----**<br> 3120-N...-...T1-...<br>**----- End of picture text -----**<br> ## **Typical applications** eee Medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, offices machines, audio equipment, machine tools ## **Your benefits** - l Maximum equipment availability is ensured by overload protection perfectly matched with the loads (prevention of nuisance tripping) and quick resettability - l Reduced mounting and wiring time - l Space saving design - **Features** l Reduced disposition and storage costs - Lo l Increased overall reliability l Single or double pole thermal circuit breaker/switch combination l Voltage ratings: AC 240 V, DC 50 V (AC 415 V upon request) l Current rating range: 0.1 … 20 A (up to 30 A upon request) Po **Further information** l Optional: push-in terminals for easy and quick wiring with a longterm stability The current data sheet as well as other relevant documents are The current data sheet as well as other relevant documents are available on our website: www.e-t-a.de/e016 - l Expandable functionality through appliance inlet module - l Functional extension options with add-on modules for low voltage release, auxiliary contact function, remote trip or fast magnetic trip - l Suitable for use in medical equipment according to IEC/EN 60601 ## Lo **Approval logos** ## **Conformity** ee **www.e-t-a.de** 2235 1 ## **3120-N...-...T1-...

For best attenuation a filter with the smallest possible current rating should be selected. Depending on the IEC/EN or UL/CSA approval, other maximum values are permissible for the inlet plug. The table above serves as orientation. For protection of the filter in the event of higher overcurrents, we recommend 3120- N circuit breakers with thermal-magnetic trip (3120- N...-M1...).

Thermal Circuit Breaker** ## **Description X3120-U undervoltage release module** The undervoltage release module reliably excludes personal injury through automatic re-start after voltage dip or power failure. **Note:** 3120- N...-H7 or -G7 basic device requires screw terminals. Not possible in combination with PT terminals. Applies in combination with design variant 4 (accordion-style): In the event of voltage dip or power failure, the undervoltage release module switches Circuit breaker off. The rocker actuator will go into centre position. Reset is effected in two steps: Step 1: Switch rocker into OFF position. Step 2: Reset circuit breaker. Not possible with style configurations D and E. ## **Typical applications** All machines that could cause personal injury upon automatic re-start, e.g. drilling machines, electric saws, meat cutting machines etc. The X3120-U02 version allows set up of a cost-effective safety circuit via the physically isolated undervoltage release module, which enables implementation for example of a remote disconnection with emergency stop. ## **Ordering information** **Type no.** **X3120** Module for 3120-N device **Module U** Undervoltage release module **Design 00** Standard (without separate connections) **01** 1 blade terminals 2.8x0.8 **02** 2 blade terminals 2.8x0.8 **Rated voltage 00** AC 230/240 V 50/60 Hz **01** AC 120 V 50/60 Hz **02** AC 100 V 50/60 Hz **03** DC 24 V **04** AC 400 V 50/60 Hz **Supply status M** Module mounted to circuit breaker 3120 **X3120- U 00 00 M** Ordering example All information and data given on our products are accurate and reliable to the best of our knowledge, but E-T-A does not accept any responsibility for the use in applications which are not in accordance with the present specification.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
