The highly sophisticated CM-S/N range in ABB’s new S-line housing offers two different types of connection terminals and is ideally suited for universal use.
Double-chamber cage connection terminals make it possible to connect fires up to 2 x 2.5 mm2 (2 x 14 AWG), rigid or fine-strand, with or without ferrules. Potential distribution does not require additional terminals.
Easy connect technology
Innovative push-in connection terminals for tool-free installation. The connection is gas-proof and has the same direction as the double-chamber cage connection terminals.
Only reliable and continuous monitoring of a three-phase network guarantees the trouble-free and economic operation of machines and installations. Thus the important parameters of three-phase systems are:
- Phase voltages
- Phase sequence
- Phase unbalance
- Phase loss
Depending on the device additional features and functions are available, as:
- Automatic phase sequence correction
- Neutral Monitoring
- Open or closed circuit operation principle
- Latching function
- Start up delay
- Tripping delay
- Restart delay
The most multifunctional devices in the EPR assortment are the CM-MPS/N monitoring relays for rated voltage levels up to 820 V AC and 400 Hz. Additionally a variety of economic and cost-efficient three-phase monitoring relays are offered in this range with specialized functionality.
Phase sequence, phase loss, unbalance and over- and undervoltage monitoring with or without neutral monitoring
Phase loss with or without neutral monitoring
Phase sequence, phase loss and over- and undervoltage monitoring
Phase sequence, phase loss and unbalance monitoring
Phase sequence, phase loss monitoring
Depending on the device: Over- and undervoltage monitoring with or without interrupted neutral monitoring or phase sequence, phase loss and over- and under voltage monitoring
Grid feeding monitor for over- and undervoltage, over- and underfrequency to monitor the phases of the public mains. The CM-UFS ensures the safe connection of decentralized power stations to the grid at all times.
