ABB Monitoring Relay, Screw Terminals, 4A Rated Switching Current - CM-MSE Series - 1SVR550801R9300

Protect your industrial motor from overheating with this monitoring relay from ABB. It uses PTC sensors to track your electrical network and trips a circuit breaker to cut power at high thermal conditions, preventing damage to downstream devices. The relay's silver cadmium oxide contacts are durable and resistant to corrosion, making them suitable for use in harsh environments. As the device resets automatically after tripping, you don't need to worry about rebooting it manually. The DIN rail mounting style is simple and doesn't need any tools, saving you time and effort.

Features & Benefits

• Wide operating temperature range of -20°C to +60°C means it's suitable for use in demanding conditions

• Green and red LED status indicators for easy monitoring and diagnostics

• Mechanical life of 30 million operating cycles for long-term operation

• Can be mounted in any position for flexibility

Applications

• Industrial conveyors

• Gas turbines

• Manufacturing plants

Are the terminals of this monitoring relay finger-safe?

Yes, the relay's terminals are rated IP20, which means they're protected from objects larger than 12mm in size, including your fingers.
