Fuses - Lauda Integral XT 150 Operating Instructions Manual

9.3.3 Fuses

Single-phase alternating current units
XT 150 (LWP 112/512/812) up to XT 350 HW (LWP 119/519/819).
In the event of an overload a circuit breaker interrupts the power supply. In an overload condition the circuit
breaker may be manually reset by returning the switch to the "I" position.
Three-phase alternating current units
XT 490 W (LWP 339/439/539) up to XT 950 WS (LWP 554).
The main switch also acts as a circuit breaker and trips when the current becomes too high. In an overload
condition the main switch may be manually reset by returning the switch to the "I" position. The compressor
circuit breaker F11 is located behind the cover panel (the main switch is fitted to the panel). In an overload
condition the compressor circuit breaker may be manually reset by returning the switch to the "I" position.
XT 1590 W (LWP 642/742) up to XT 1850 WS (LWP 533).
The illustration shows the motor circuit breaker F100 and the compressor circuit breaker F11 behind the
cover panel. The main switch (rotary switch) is fitted to the cover panel. In an overload condition the circuit
breaker may be manually reset by returning the switch to the "I" position.
View from the front into the device.
Also, high ambient temperatures (approx. 45 to 50 °C) can trip a circuit breaker (fuse).
If the circuit breaker trips again, then the cause must be found by the LAUDA Service Constant Tempera-
ture Equipment.
