SCOPE OF APPLICATION
TXL7-63 Miniature Circuit Breaker (10KA Miniature Circuit Breaker), mainly used for protection distribution lines of AC 50Hz / 60Hz, rated voltage of 110V, 230V(220V), 400V (380V), rated current of 1A, 3A, 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, 60A and 63A, rated short-circuit breaking capacity is 10KA or below, and used for the lines of not frequent making, breaking and conversion, with overload, short circuit protection. At the same time, the 10KA MCB has a strong auxiliary function modules, such as auxiliary contacts, indication contacts with alarm, shunt release, undervoltage release remote trip control and other modules.
TXL7-63 Miniature Circuit Breaker (10KA MCB) complies with standards of GB10963.1, IEC60898-1 standard.
NORMAL OPERATING AND INSTALLATION CONDITIONS
The upper limit of ambient air temperature shall not exceed +40°C, the lower limit shall not be lower than -5°C, and the 24-hour average temperature shall not exceed +35°C.
The altitude of the installation site should not exceed 2000m.
The relative humidity of the atmosphere does not exceed 50% when the ambient air temperature is +40°C. Higher relative humidity is allowed at lower temperatures. Special measures should be taken for condensation that occasionally occurs on the surface of the product due to temperature changes. .
Pollution level: Class II.
Installation conditions: Install in a place without significant shock and vibration, and in a medium without explosion hazard.
Installation method: use TH35-7.5 mounting rail to install.
Installation category: II, III.
