Extended Description
1SVR740840R0600 ABB: The CM-SRS.M1P is a multifunctional current monitoring relay from the CM single-phase monitors range. This monitoring relay operates with a rated control supply voltage of 24 - 240 V AC / DC and has a 2 c/o (SPDT) output with contacts rated at 250 V / 4 A. It provides a RMS measuring principle for DC and AC currents with 3 measuring ranges: 3-30 mA, 10-100 mA and 0.1-1 A. The CM-SRS.M1P offers selection of over- or undercurrent monitoring, open- or closed-circuit operating principle, with or without latching function. The hysteresis is adjustable within a range of 3 to 30 % of the threshold value. The tripping delay and the start-up delay are adjustable over a range of instantaneous to 30 s (0, 0.1-30 s). A sealable transparent cover for protection against unauthorized changes is available as accessory. The device offers maintenance free Easy Connect Technology with push-in terminals.

FAQs
The CM-SRS.M1P is designed for TH35-15 or TH35-7.5 DIN rails and uses screwless push-in terminals, enabling rapid, error-free wiring. This simplifies retrofits in existing panels and supports quick field changes without specialized tooling, reducing commissioning time and improving installer confidence.
It measures current RMS in three ranges: 3-30 mA, 10-100 mA, and 0.1-1 A, with 2 c/o SPDT contacts rated up to 250 V and 4 A. The device supports open- or closed-circuit monitoring with selectable operating principle and configurable delay ranges, offering flexible protective signaling for motor and load monitoring.
Ideal for single-phase power monitoring in automation cabinets, machine cells, and packaging lines. It supports adjustable tripping/start-up delays and hysteresis to suit equipment startup surges and load variations, reducing nuisance trips while ensuring timely alerts in safety interlock circuits.
The device carries CE marking and UL/CSA certifications, with CAN/CSA and UKCA readiness in the broader CM-SxS family. It also features IP50 housing for protection against dust and incidental contact, meeting typical industrial control panel safety requirements.
Maintenance-free Easy Connect push-in terminals reduce wiring time and field faults. Electrical durability is rated for AC-12 100,000 cycles, with mechanical durability up to 30,000,000 operations, delivering lower lifecycle costs, fewer panel downtime events, and faster deployment in new builds or upgrades.
