The Siemens 3RV1042-4JA10 is a robust and reliable circuit breaker of size S3. With an A-release range of 45 to 63 A and an N-release of 819A, it offers motor protection up to 100 KA. This circuit breaker is part of the SIRIUS product line, known for its high-quality and performance.
The 3RV1042-4JA10 is designed with a screw connection for increased breaking capacity. It features three poles for the main current circuit and offers overload protection and phase disturbance recognition. However, it does not include a removable terminal for auxiliary and control circuit, short-circuit to earth recognition, auxiliary switch, undervoltage release mechanism, or trip indicator.
This circuit breaker is also equipped with an auxiliary switch and an optional motor drive. It has an impulse voltage resistance rated value of 6,000 V and offers a protection class IP on the front of IP20, ensuring it is finger-safe.
The 3RV1042-4JA10 is designed for screw and snap-on mounting onto a 35mm standard mounting rail according to DIN EN 50022. It can be installed in any position and has dimensions of 174mm depth, 165mm height, and 70mm width. The arrangement of electrical connectors for the main current circuit is on the front side, and the design of the electrical connection for both the main current circuit and auxiliary and control current circuit is screw-type terminals.
With a trip class of CLASS 10 and an adjustable response current of the current-dependent overload release of 45 to 63 A, the 3RV1042-4JA10 is a reliable choice for your circuit protection needs.
