The 3VA11 4P 63A 55KA Circuit Breaker is a low voltage IEC molded case circuit breaker equipped with a thermal-magnetic trip unit. This device is constructed with a frame that allows for medium breaking capacity, specifically rated at 63A and capable of handling 55kA at 415V. The unit features a TM220 trip mechanism, which provides adjustable overload protection settings from 44A to 63A, along with short-circuit protection at 10 times the nominal current (Ii).
Designed for effective line protection, this circuit breaker includes a neutral protection feature at 100% with a nut keeper kit for secure connections. The breaker is suitable for installation on DIN rails and has a degree of protection rated at IP40. Additionally, it supports a front-side connection for the main current circuit and utilizes a screw connection for electrical integration.
With dimensions of 4 x 5.1 x 3.5 inches, this built-in device is versatile for various applications. It is important to note that while the circuit breaker can accommodate an optional motor drive, it does not come with integrated earth fault protection or under voltage release.
