Circuit-breakers LZM1, 2, 3, 4 and switch-disconnectors LN1, 2, 3, 4up to 1600 A

Reliably and safely controlling, switching and managing power, in industry, in buildings and in machine construction. Enabled by innovative protection concepts.

Circuit-breaker series LZM1 to LZM4,switch-disconnectors LN1 to LN4- just 4 compact frame sizes - available as 3 and 4-pole device- now also up to 1600 A- fl exible mounting using modular function groups- full rated current at 50 °C ambient temperature- switch suitable for world-wide use

Page 6, page 18

Standard/trip-indicating auxiliary contact from the Titan range- reduced number of variants and stockholding requirement- simple front installation at the same position- simple clip-on feature saves mounting costs- attractively priced identical parts from the control circuit

device range

Page 42

Door coupling rotary handles- identical drilling template for all

variants- innovative automatic centring- axis support for long-term reliable

operation - side-wall operation ensuring space-

saving main switch installation

Page 54

Remote operators- common functional concept of all

variants- low closing delays 60 ms to 100 ms- locking and sealing features provide

security

EngineeringMCB, back-up protection

Protection of PVC insulated cables against thermal overload with short-circuitsAccording to VDE 0100 part 430 cables and conductors must be protected against short-circuit and overload. The overload protection is obtained by using LZM circuit-breakers with settable, current-dependent, delayed overload release.

Short-circuit protection is provided by adjustable instantaneous releases, which open the main contacts in less than 25 ms. The short-circuit total opening time restricts the temperature rise of the cable to a minimum.

The tables indicate the minimum conductor cross-section reliably protected by circuit-breakers during a short-circuit. (Operating voltage UN = 415 V)

Where the prospective fault current at the point of installation of circuit-breakers is very high, it is conventional to use LZMN current-limiting circuit-breakers. An attractively priced alternative is to fit a LZMN current-limiting circuit-breaker upstream of LZMB(C) standard circuit-breakers, if the fault level is too high for LZMB(C) switches.

The table shows which current-limiting circuit-breaker LZMN in combination with LZMB(C) are to be used to provide protection at the network locations with high short-circuit capacities.

The selectivity limit is determined by the response current of the non-delayed short-circuit release in the upstream incoming circuit-breaker. In many applications this is sufficient.

Notes With temperatures which deviate from the reference temperature, a slight change of the overload protection properties occurs. In order to determine the release time using the tripping characteristics the temperature compensation coefficient in accordance with the table must be considered.Example: An LZM1-A100 is calibrated for a reference temperature of 40 °C.

What happens when it is operated at an ambient temperature of 60 °C? At 60 °C, the temperature compensation coefficient of 0.86 results in a reduced operating current of Ir = 100 A x 0.86 = 86 A. In other words at an ambient temperature of 60 °C the LZM1-A100 trips as if it were set to 86 A.

Notes The derating coefficient must be considered in accordance with the following table in order to determine the maximum permissible current loading at different ambient temperatures.Example: An LZM2-A250 should be operated at an ambient temperature of 65 °C.

How high is the permissible rated operational current Ie? At 65 °C the derating coefficient is 0.85, this means Ie = 250 A x 0.85 = 212.5 A. The LZM2-A250 may be operated at an ambient temperature of 65 °C with a maximum Ie = 212.5 A.
