Complete range of UL 489 listed DIN rail mounted miniature circuit breakers up to 40A current rating. Standard ratings of 10 kAIC up to 277/480 VAC. Select amperages available at 14 kAIC up to 277/480 VAC and 10 kAIC up to 125 Vdc per pole. Current limiting design provides fast short-circuit interruption that reduces the let-through energy, which can damage the circuit. Suitable for branch circuit device protection. Thermal-magnetic overcurrent protection. Three levels of short circuit protection, categorized by B, C and D curves. Trip-free design-breaker can not be defeated by holding the handle in the ON position. Captive screws cannot be lost. SWD (switching duty)- suitable for switching fluorescent lighting loads (In = 20A). Fulfill UL 489, CSA C22.2 No.5 and also IEC 60947-2 Standard. For use in applications for which UL 1077 or CSA C22.2 No.235 are also allowed. Field-installable shunt trip and auxiliary switch subsequent mounting. Separate version for ring tongue connection (Type FAZ-RT), terminal screws can be removed (on both sides). Module width of only 17.7 mm (per pole). Contact Position Indicator (red/green). Easy installation on DIN rail. Possibility for sealing the toggle in ON or OFF position.
