Frequently Asked Questions
Q: What does the model number XT5S 400 Ekip Dip LS/I In=400 3p F F represent?
A: The model number breaks down as follows: XT5S = Tmax XT5 frame size, Standard breaking capacity; 400 = 400 A rated current; Ekip Dip LS/I = Electronic trip unit with Long-time and Instantaneous protection; In=400 = Rated current 400 A; 3p = Three-pole configuration; F F = Fixed version with Front terminals on both line and load sides.
Q: What is the difference between the Ekip Dip LS/I and TMA trip units?
A: The Ekip Dip LS/I is an electronic trip unit providing adjustable Long-time (overload) and Instantaneous (short-circuit) protection with high accuracy. The TMA (Thermal-Magnetic Adjustable) is a traditional thermal-magnetic trip unit. Electronic trip units offer superior precision, repeatability, and typically more flexible setting ranges.
Q: What is the breaking capacity of this circuit breaker?
A: The XT5S 400 has a rated ultimate short-circuit breaking capacity (Icu) of 85 kA at 220-240 V AC, 50 kA at 380-440 V AC, 30 kA at 500-525 V AC, and 25 kA at 690 V AC.
Q: Can this breaker be motorized for remote operation?
A: Yes, motor drive operation is available as an optional accessory. This enables remote opening and closing of the circuit breaker for automated power management and SCADA integration.
Q: What accessories are available for this circuit breaker?
A: The XT5S 400 is compatible with a comprehensive range of accessories including auxiliary contacts (NO/NC), shunt trips, undervoltage releases, rotary handles, motor operators, and communication modules for advanced monitoring.
Q: What is the rated voltage and insulation level?
A: The breaker has a rated operational voltage (Ue) of 690 V AC and a rated insulation voltage (Ui) of 1000 V. The rated impulse withstand voltage (Uimp) is 8 kV.
Q: What is the difference between the XT5S and XT5H versions?
A: The XT5S is the standard breaking capacity version (50 kA at 400 V), while the XT5H is the high breaking capacity version (70 kA at 400 V). The XT5S is suitable for most industrial applications, while the XT5H is used where higher fault currents are expected.
