FAQs
The CM-MSS.41P family, including 1SVR740712R1200, is designed for TH35-7.5 or TH35-15 DIN rails and uses push-in terminals for quick wiring. It supports flexible mounting position from 1 to 6 and accepts standard 2x0.5 to 1.5 mm² conductors, making it straightforward to drop into existing panels and minimize rework during retrofits.
The device operates from 24 to 240 V AC/DC control supply and provides 2 c/o (SPDT) outputs. This supports common interlock and fault signaling architectures in motor protection schemes, enabling simple integration with PLCs, starter circuits, and safety interlocks across varied motor drives.
Yes. The CM-MSS.41P carries ATEX certification and CE conformity, with UL/CSA recognition in many markets. These certifications, combined with IP50 housing, ensure safe operation in hazardous zones and general factory environments, simplifying approvals for global installations.
Key features include programmable short-circuit detection, PTC sensor monitoring, and non-volatile fault storage (configurable). These capabilities support fast fault diagnosis, remote or manual resets, and reliable fault logging, reducing unplanned downtime in high-demand applications such as conveyors, pumps, and presses.
With a compact 22.5 mm width, 85.6 mm height, 103.7 mm depth, and a weight of 0.13 kg, the relay fits compact panels easily. DIN rail mounting, screwless terminals, and a sealable cover accessory simplify installation, improve panel density, and cut commissioning time for multi-machine lines in manufacturing environments.
