3120-N...-...T1-... Thermal Circuit Breaker
2118

Description
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 IEC/EN
61058 (see data sheet switch 3120-N...Q1). 3120-N...-...T1-...

The current rating of the circuit breaker must not be higher than the
filter current rating. For best attenuation a filter with the smallest pos-
sible 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...).

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.

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.

3120-N...-...T1-... Thermal Circuit Breaker
Description
The 3120- N...-...M1-... thermal-magnetic circuit breaker/switch
combination
unites overcurrent protection and the function of an ON/
OFF switch within a single component.
The integral thermobimetal
ensures ideally matched overload protection. The magnetic trip
module trips the circuit breaker/switch combination at overload
currents from four times rated current within milliseconds.
The 3120- N...-...M1-... meets the fire resistance requirements to
EN 60335-1: 2007-02 Safety of household and similar electrical
appliances.
Typical applications
Electric motors, household appliances and office machines, electrical
tools, power supplies, charging rectifiers

The time/current characteristics depend on the ambient temperature. In order
to eliminate nuisance or late tripping, please multiply the current rating of
