FAQ
FAQ
Q1: What is the ABB CM-MPS.21 1SVR630885R3300?
A: It is an ABB multifunctional three-phase monitoring relay used to supervise electrical supply conditions.
Q2: What voltage does the CM-MPS.21 monitor?
A: It monitors three-phase voltages in the 180–280 V AC range. It can also be used for single-phase mains monitoring.
Q3: What faults can this relay detect?
A: It monitors phase sequence, phase failure, overvoltage, undervoltage, phase unbalance and interrupted neutral conditions.
Q4: Does the CM-MPS.21 have adjustable delay?
A: Yes. The tripping delay can be set to 0 seconds or 0.1–30 seconds, with selectable ON- or OFF-delay operation.
Q5: How many output contacts does it have?
A: It has 2 changeover contacts (2 c/o, SPDT), providing two relay output channels.
Q6: How is the 1SVR630885R3300 installed?
A: It is designed for tool-free snap-on mounting to a standard DIN rail according to IEC/EN 60715.
Q7: What are the dimensions and weight?
A: The unit is approximately 22.5 × 85.6 × 103.7 mm and weighs about 0.146 kg.
Q8: Is 1SVR630885R3300 the same as the newer CM-MPS.21S?
A: Functionally, it belongs to the same CM-MPS.21 screw-terminal version family. ABB’s newer catalog uses 1SVR730885R3300 for CM-MPS.21S, while 1SVR630885R3300 is the older order code. For replacement, verify the terminal arrangement and product revision before ordering.
