Product Description

ABB 1SVR740700R0200 CM-MSS.22P Monitoring Relay is a dual-pole double throw (DPDT) relay designed for precise motor temperature monitoring using PTC temperature sensors integrated into motor windings. The device operates with a supply voltage of 24 V DC or AC and mounts securely on DIN rails, making it suitable for industrial and commercial electrical control panels.

This relay supports dynamic interrupted wire detection and short circuit monitoring of the sensor circuit, ensuring reliable and safe motor protection in demanding environments. With its wide supply voltage range of 24 to 240 V AC/DC, it caters to diverse installation requirements.

The non-volatile fault storage maintains fault history to aid diagnostics, while remote reset functionality simplifies system recovery after motor faults. Terminal options include screw connection or Easy Connect technology, allowing flexible installation choices.

Measuring 103.7 mm in length and 85.6 mm in height, the compact form factor supports standard DIN rail mounting and installation in confined spaces. The relay features a contact current rating of 3.7 mA and an IP rating of IP20, IP50, providing adequate protection against dust and accidental contact.

Designed as part of ABB's CM-MSS series, this monitoring relay is made in Germany and fulfills the needs for heavy-duty motor starting, high ambient temperature conditions, insufficient cooling detection, and motor winding unbalance monitoring.

Temperature sensing via PTC thermistor. Dynamic interrupted wire detection ensures sensor circuit integrity. Wide voltage range compatibility with 24-240 V AC/DC supply. Short circuit monitoring capability in the sensor line.

Non-volatile fault logging for reliable diagnostics. Remote reset function enhances system usability. Screw and Easy Connect terminal options for flexible wiring. Compact DIN rail mount form factor with IP20/IP50 protection.

This industrial-grade monitoring relay is ideal for use in electrical automation, motor protection, HVAC systems, manufacturing processes, and other commercial applications requiring reliable temperature monitoring and fault detection.
